Universality of weakly bound dimers and Efimov trimers close to Li-Cs Feshbach resonances  

E-Print Network (OSTI)

We study the interspecies scattering properties of ultracold Li-Cs mixtures in their two energetically lowest spin channels in the magnetic field range between 800 G and 1000 G. Close to two broad Feshbach resonances we create weakly bound LiCs dimers by radio-frequency association and measure the dependence of the binding energy on the external magnetic field strength. Based on the binding energies and complementary atom loss spectroscopy of three other Li-Cs s-wave Feshbach resonances we construct precise molecular singlet and triplet electronic ground state potentials using a coupled-channels calculation. We extract the Li-Cs interspecies scattering length as a function of the external field and obtain almost a ten-fold improvement in the precision of the values for the pole positions and widths of the s-wave Li-Cs Feshbach resonances as compared to our previous work [Pires \\textit{et al.}, Phys. Rev. Lett. \\textbf{112}, 250404 (2014)]. We discuss implications on the Efimov scenario and the universal geome...

Structural Characterization of Li  

SciTech Connect

Pristine Li{sub 1-z-x}Ni{sub 1+z}O{sub 2} (z=0.02, 0.07, and 0.25) and deintercalated Li{sub x}Ni{sub 1.02}O{sub 2} (x=0.82 and 0.63) phases were characterized by neutron diffraction. In all cases, the amount of nickel in the lithium sites was found to be identical to that deduced from X-ray diffraction experiments. The sensitivity of the neutron studies allowed us to show that no lithium ions are in the NiO{sub 2} slabs for z=0.02 and 0.07. A Li/Ni mixing appears only for the most lithium-deficient phase leading to the [Li{sub 0.73}Ni{sub 0.27}]{sub 3b}[Ni{sub 0.98}Li{sub 0.02}]{sub 3a}O{sub 2} cationic distribution for the Li{sub 0.75}Ni{sub 1.25}O{sub 2} phase. Determination of the anisotropic atomic displacement parameters confirms the results previously obtained from EXAFS data. The structural characterization of partially deintercalated phases was in good agreement with the XRD analysis. However, in the case of Li{sub 0.63}Ni{sub 1.02}O{sub 2}, it gave evidence for the presence of a small amount of rhombohedral phase due to fluctuations in the composition of the starting material.

Electronic Properties of LiFePO4 and Li doped LiFePO4  

SciTech Connect

The potential use of different iron phosphates as cathodematerials in lithium-ion batteries has recently been investigated.1 Oneof the promising candidates is LiFePO4. This compound has severaladvantages in comparison to the state-of-the-art cathode material incommercial rechargeable lithium batteries. Firstly, it has a hightheoretical capacity (170 mAh/g). Secondly, it occurs as mineraltriphylite in nature and is inexpensive, thermally stable, non-toxic andnon-hygroscopic. However, its low electronic conductivity (~;10-9 S/cm)results in low power capability. There has been intense worldwideresearch activity to find methods to increase the electronic conductivityof LiFePO4, including supervalent ion doping,2 introducingnon-carbonaceous network conduction3 and carbon coating, and theoptimization of the carbon coating on LiFePO4 particle surfaces.4Recently, the Li doped LiFePO4 (Li1+xFe1-xPO4) synthesized at ARL hasyield electronic conductivity increase up to 106.5 We studied electronicstructure of LiFePO4 and Li doped LiFePO4 by synchrotron based soft X-rayemission (XES) and X-ray absorption (XAS) spectroscopies. XAS probes theunoccupied partial density of states, while XES the occupied partialdensity of states. By combining XAS and XES measurements, we obtainedinformation on band gap and orbital character of both LiFePO4 and Lidoped LiFePO4. The occupied and unoccupied oxygen partial density ofstates (DOS) of LiFePO4 and 5 percent Li doped LiFePO4 are presented inFig. 1. Our experimental results clearly indicate that LiFePO4 has wideband gap (~; 4 eV). This value is much larger than what is predicted byDFT calculation. For 5 percent Li doped LiFePO4, a new doping state wascreated closer to the Fermi level, imparting p-type conductivity,consistent with thermopower measurement. Such observation substantiatesthe suggestion that high electronic conductivity in Li1.05Fe0.95 PO4 isdue to available number of charge carriers in the material. Furthermore,Hall effect measurement on Li doped sample confirmed presence of freecharge carriers, which are responsible for the observed electronicconductivity increase in Li doped LiFePO4. There is no evidence that Fe3+valence is created by doping with excessive Li+ in Li1.05Fe0.95PO4, asshown by Fe-edge XAS. (Fig.2) Instead, charge-carrier holes resideprimarily in unoccupied O 2p states, which compensate for the chargedeficiency from Li+ substitution for Fe2+. The increased conductivity inLi1.05Fe0.95PO4 is attributed to the new charge carriers (doped holes)and the strong electron correlation between O 2p and Fe 3dstates.

Graphene/Li-ion battery  

Science Journals Connector (OSTI)

Density function theory calculations were carried out to clarify storage states of Lithium (Li) ions in graphene clusters. The adsorption energy spin polarization charge distribution electronic gap surface curvature and dipole momentum were calculated for each cluster. Li-ion adsorbed graphene doped by one Li atom is spin polarized so there would be different gaps for different spin polarization in electrons. Calculation results demonstrated that a smaller cluster between each two larger clusters is preferable because it could improve grapheneLi-ion batteries; consequently the most proper graphene anode structure has been proposed.

LiFePO{sub 4} has several potential advantages in comparison to the transition metal oxide cathode materials used in commercial lithium-ion batteries. However, its low intrinsic electronic conductivity ({approx} 10{sup -9} S/cm) is problematic. We report here a study by soft x-ray absorption/emission spectroscopy of the electronic properties of undoped LiFePO{sub 4} and Li-doped LiFePO{sub 4} in which Li{sup +} ions are substituted for Fe{sup 2+} ions in an attempt to increase the intrinsic electronic conductivity. The conductivities of the Li{sub 1+x}Fe{sub 1-x}PO{sub 4} samples were, however, essentially unchanged from that of the undoped LiFePO{sub 4}. Nonetheless, evidence for changing the electronic properties of LiFePO{sub 4} by doping with excess Li+ was observed by the XAS/XES spectroscopy. New pre-edge features the O-1s XAS spectrum of Li{sub 1.05}Fe{sub 0.95}PO4 is a direct indication that the charge compensation for substitution of Fe{sup 2+} by Li{sup +} resides in the unoccupied O-2p orbitals. A charge transfer (CT) excitation was also observed in the doped material implying that the unoccupied O-2p orbitals created by doping are strongly hybridized with unoccupied Fe-3d orbitals of neighboring sites. However, the strong covalent bonding within the (PO{sub 4}){sup 3-} anions and the large separation of the Fe cations means that the charge created by doping is not delocalized in the manner of electrons or holes in a semiconductor.

Fabrication of Li-intercalated bilayer graphene  

Science Journals Connector (OSTI)

We have succeeded in fabricating Li-intercalated bilayer graphene on silicon carbide. The low-energy electron diffraction from Li-deposited bilayer graphene shows a sharp 3 3 R 30 pattern in contrast to Li-deposited monolayer graphene. This indicates that Li atoms are intercalated between two adjacent graphene layers and take the same well-ordered superstructure as in bulk C6Li. The angle-resolved photoemission spectroscopy has revealed that Li atoms are fully ionized and the ? bands of graphene are systematically folded by the superstructure of intercalated Li atoms producing a snowflake-like Fermi surface centered at the ? point. The present result suggests a high potential of Li-intercalated bilayer graphene for application to a nano-scale Li-ion battery.

Tailoring Li adsorption on graphene  

Science Journals Connector (OSTI)

The technological potential of functionalized graphene has recently stimulated considerable interest in the study of the adsorption of metal atoms on graphene. However, a complete understanding of the optimal adsorption pattern of metal atoms on a graphene substrate has not been easy because of atomic relaxations at the interface and the interaction between metal atoms. We present a partial particle swarm optimization technique that allows us to efficiently search for the equilibrium geometries of metal atoms adsorbed on a substrate as a function of adatom concentration. Using Li deposition on graphene as an example we show that, contrary to previous works, Li atoms prefer to cluster, forming four-atom islands, irrespective of their concentration. We further show that an external electric field applied vertically to the graphene surface or doping with boron can prevent this clustering, leading to the homogeneous growth of Li.

Nanoscale LiFePO4 and Li4Ti5O12 for High Rate Li-ion Batteries  

SciTech Connect

The electrochemical performances of nanoscale LiFePO4 and Li4Ti5O12 materials are described in this communication. The nanomaterials were synthesized by pyrolysis of an aerosol precursor. Both compositions required moderate heat-treatment to become electrochemically active. LiFePO4 nanoparticles were coated with a uniform, 2-4 nm thick carbon-coating using an organic precursor in the heat treatment step and showed high tap density of 1.24 g/cm3, in spite of 50-100 nm particle size and 2.9 wtpercent carbon content. Li4Ti5O12 nanoparticles were between 50-200 nm in size and showed tap density of 0.8 g/cm3. The nanomaterials were tested both in half cell configurations against Li-metal and also in LiFePO4/Li4Ti5O12 full cells. Nano-LiFePO4 showed high discharge rate capability with values of 150 and 138 mAh/g at C/25 and 5C, respectively, after constant C/25 charges. Nano-Li4Ti5O12 also showed high charge capability with values of 148 and 138 mAh/g at C/25 and 5C, respectively, after constant C/25 discharges; the discharge (lithiation) capability was comparatively slower. LiFePO4/Li4Ti5O12 full cells deliver charge/discharge capacity values of 150 and 122 mAh/g at C/5 and 5C, respectively.

Mixed Salts of LiTFSI and LiBOB for Stable LiFePO4-Based Batteries at Elevated Temperatures  

SciTech Connect

To achieve stable long-term cycling stability at elevated temperatures, mixed salts of LiTFSI and LiBOB are used to replace LiPF6 salt in non-aqueous electrolytes for LiFePO4-based batteries. It is found that adding LiBOB in LiTFSI-based electrolytes effectively prevents the severe corrosion to Al current collectors that often is observed in LiTFSI-based electrolytes, which have high thermal stability. The cells using LiTFSI-LiBOB-based electrolytes demonstrate superior high temperature (60 ?C) stability and very similar room temperature performance (i.e., cycling stability and rate capability) when compared to cells using the LiPF6-based electrolyte.

Two-phase transition of Li-intercalation compounds in Li-ion batteries  

Science Journals Connector (OSTI)

Among all electrode materials, olivine LiFePO4 and spinel Li4Ti5O12 are well-known for their two-phase structure, characterized by a flat voltage plateau. The phase transition in olivine LiFePO4 may be modeled in single particle and many-particle systems at room temperature, based on the thermodynamic phase diagram which is easily affected by coherency strain and the size effect. Some metastable and transient phases in the phase diagram can also be detected during non-equilibrium electrochemical processes. In comparison to olivine LiFePO4, spinel Li4Ti5O12 possesses a zero strain property and performs Li-site switching during the phase transition, which lead to a different phase structure. Here, the phase transitions of olivine LiFePO4 and spinel Li4Ti5O12 are systematically reviewed, and the concepts discussed may be extended to other two-phase Li-intercalation compounds in Li-ion batteries.

LiDAR LiDAR Jump to: navigation, search Dictionary.png LiDAR Light Detection and Ranging (LiDAR) is an active remote sensing technology that uses optical measurements of scattered light to find range (Young, 2006). Measurements can be made from aircraft- or land-based sensors. Distance to an object is determined by the time delay between transmission and detection of a laser pulse. It is accurate to within 0.1 m (at 1-m resolution, 0.3 m at 3-m resolution) and has the ability to measure the land surface elevation beneath the vegetation canopy.

Comment on Li pellet Conditioning in TFTR  

SciTech Connect

Li pellet conditioning in TFTR results in a reduction of the edge electron density which allows increased neutral beam penetration, central heating, and fueling. Consequently the temperature profiles became more peaked with higher central Ti, Te, and neutron emission rates.

Ambient Operation of Li/Air Batteries  

SciTech Connect

In this work, Li/air batteries based on nonaqueous electrolytes were investigated in ambient conditions (with an oxygen partial pressure of 0.21 atm and relative humidity of ~20%). A heat-sealable polymer membrane was used as both an oxygen-diffusion membrane and as a moisture barrier for Li/air batteries. The membrane also can minimize the evaporation of the electrolyte from the batteries. Li/air batteries with this membrane can operate in ambient conditions for more than one month with a specific energy of 362 Wh kg-1, based on the total weight of the battery including its packaging. Among various carbon sources used in this work, Li/air batteries using Ketjenblack (KB) carbon-based air electrodes exhibited the highest specific energy. However, KB-based air electrodes expanded significantly and absorbed much more electrolyte than electrodes made from other carbon sources. The weight distribution of a typical Li/air battery using the KB-based air electrode was dominated by the electrolyte (~70%). Lithium-metal anodes and KB-carbon anodes account for only 5.12% and 5.78% of the battery weight, respectively. We also found that only ~ 20% of the mesopore volume of the air electrode was occupied by reaction products after discharge. To further improve the specific energy of the Li/air batteries, the microstructure of the carbon electrode needs to be further improved to absorb much less electrolyte while still holding significant amounts of reaction products

Li-Ion Battery with LiFePO4 Cathode and Li4Ti5O12 Anode for Stationary Energy Storage  

SciTech Connect

i-ion batteries based on commercially available LiFePO4 cathode and Li4Ti5O12 anode were investigated for potential stationary energy storage applications. The full cell that operated at flat 1.85V demonstrated stable cycling for 200 cycles followed by a rapid fade. A significant improvement in cycling stability was achieved via Ketjen black coating of the cathode. A Li-ion full cell with Ketjen black modified LiFePO4 cathode and an unmodified Li4Ti5O12 anode exhibited negligible fade after more than 1200 cycles with a capacity of ~130mAh/g. The improved stability, along with its cost-effectiveness, environmentally benignity and safety, make the LiFePO4/ Li4Ti5O12 Li-ion battery a promising option of storing renewable energy.

Rate-dependent morphology of Li2O2 growth in Li-O2 batteries  

E-Print Network (OSTI)

Compact solid discharge products enable energy storage devices with high gravimetric and volumetric energy densities, but solid deposits on active surfaces can disturb charge transport and induce mechanical stress. In this Letter we develop a nanoscale continuum model for the growth of Li2O2 crystals in lithium-oxygen batteries with organic electrolytes, based on a theory of electrochemical non-equilibrium thermodynamics originally applied to Li-ion batteries. As in the case of lithium insertion in phase-separating LiFePO4 nanoparticles, the theory predicts a transition from complex to uniform morphologies of Li2O2 with increasing current. Discrete particle growth at low discharge rates becomes suppressed at high rates, resulting in a film of electronically insulating Li2O2 that limits cell performance. We predict that the transition between these surface growth modes occurs at current densities close to the exchange current density of the cathode reaction, consistent with experimental observations.

The X^- Solution to the ^6Li and ^7Li Big Bang Nucleosynthesis Problems  

E-Print Network (OSTI)

The $^6$Li abundance observed in metal poor halo stars appears to exhibit a plateau as a function of metallicity similar to that for $^7$Li, suggesting a big bang origin. However, the inferred primordial abundance of $^6$Li is $\\sim$1000 times larger than that predicted by standard big bang nucleosynthesis for the baryon-to-photon ratio inferred from the WMAP data. Also, the inferred $^7$Li primordial abundance is 3 times smaller than the big bang prediction. We here describe in detail a possible simultaneous solution to both the problems of underproduction of $^6$Li and overproduction of $^7$Li in big bang nucleosynthesis. This solution involves a hypothetical massive, negatively-charged leptonic particle that would bind to the light nuclei produced in big bang nucleosynthesis, but would decay long before it could be detected. We consider only the $X$-nuclear reactions and assume that the effect of decay products is negligible, as would be the case if lifetime were large or the mass difference between the charged particle and its daughter were small. An interesting feature of this paradigm is that, because the particle remains bound to the existing nuclei after the cessation of the usual big bang nuclear reactions, a second longer epoch of nucleosynthesis can occur among $X$-nuclei. We confirm that reactions in which the hypothetical particle is transferred can occur that greatly enhance the production of $^6$Li while depleting $^7$Li. We also identify a new reaction that destroys large amounts of $^7$Be, and hence reduces the ultimate $^7$Li abundance. Thus, big-bang nucleosynthesis in the presence of these hypothetical particles, together with or without an event of stellar processing, can simultaneously solve the two Li abundance problems.

General limit on the relation between abundances of D and $^7$Li in big bang nucleosynthesis with nucleon injections  

E-Print Network (OSTI)

The injections of energetic hadrons could have occurred in the early universe by decays of hypothetical long-lived exotic particles. The injections induce the showers of nonthermal hadrons via nuclear scattering. Neutrons generated at these events can react with $^7$Be nuclei and reduce $^7$Be abundance solving a problem of the primordial $^7$Li abundance. We suggest that thermal neutron injection is a way to derive a model independent conservative limit on the relation between abundances of D and $^7$Li in a hadronic energy injection model. We emphasize that an uncertainty in cross sections of inelastic $n+p$ scattering affects the total number of induced neutrons, which determines final abundances of D and $^7$Li. In addition, the annihilations of antinucleons with $^4$He result in higher D abundance and trigger nonthermal $^6$Li production. It is concluded that a reduction of $^7$Li abundance from a value in the standard big bang nucleosynthesis (BBN) model down to an observational two $\\sigma$ upper limit is necessarily accompanied by an undesirable increase of D abundance up to at least an observational 12 $\\sigma$ upper limit from observations of quasi-stellar object absorption line systems. The effects of antinucleons and secondary particles produced in the hadronic showers always lead to a severer constraint. The BBN models involving any injections of extra neutrons are thus unlikely to reproduce a small $^7$Li abundance consistent with observations.

Nuclear Magnetic Relaxation in LiF at High Temperatures  

Science Journals Connector (OSTI)

Measurements of T1 and T2, the spin-lattice and spin-spin relaxation times, are reported for Li7 and F19 nuclei in a single crystal of LiF. T1(Li) has been measured from room temperature to the melting point (1120K) and the other quantities from 830K to the melting point. Above 620K, relaxation is caused exclusively by the diffusion of Li and F ions. T1(Li), T2(Li), and T1(F) are mainly determined by ?Li, the jump frequency of Li ions, and T2(F) mainly by ?F. Using a theory of relaxation developed elsewhere, ?Li and ?F are obtained for the region of intrinsic diffusion as ?Li=1.71016exp(-1.81eV/kT) and ?F=4.51017exp(-2.2eV/kT). For the extrinsic region, the motional activation energy of Li ions is obtained as 0.71 eV. The values of ?Li are in good agreement with those obtained from conductivity measurements; to our knowledge, ?F has never been measured by other methods. Below 620K quadrupolar relaxation due to lattice vibrations and relaxation by paramagnetic impurities become important, and rough values are obtained for these contributions to T1(Li). Large angular variations of T1 and T2 are observed in the region of relaxation due to atomic diffusion. T2(Li) and T1(Li) vary by a factor of 2 and 1.5, respectively, as a function of crystal orientation, in good agreement with theoretical prediction. A crude measurement of T1(Li) in molten LiF is discussed.

Molecular dynamics of LiF melting  

Science Journals Connector (OSTI)

We performed molecular-dynamics simulations of the melting and/or freezing of LiF. The simulations were done using the Tosi-Fumi model and our own model of interatomic interactions. The latter was verified by ab initio calculations of the equation of state for LiF. We show that the recent molecular-dynamics calculations by Boehler and co-workers are not adequate and their model for the interactions is not capable of providing melting temperatures in agreement with experiment. Our calculated pressure dependence of the melting temperatures gives valuable information. We found that the B1-B2 transition in LiF at around 1 Mbar removes the discrepancy between the diamond-anvil cell and shockwave melting temperatures. An explanation of the controversy between low and high melting temperatures obtained from diamond-anvil cell experiments is suggested.

First principles calculations have been performed on the Lithium hydride (LiH) using the full potential linearized augmented plane wave (FP-LAPW) method within the framework of density functional theory. We have extended our calculations for LiH+2H and LiH+6H in NaCl structure. The structural stability of three compounds have been studied. It is found that LiH with 6 added Hydrogen atoms is most stable. The obtained results for LiH are in good agreement with reported experimental data. Electronic structures of three compounds are also studied. Out of three the energy band gap in LiH is ?3.0 eV and LiH+2H and LiH+6H are metallic.

Making Li-air batteries rechargeable: material challenges  

SciTech Connect

A Li-air battery could potentially provide three to five times higher energy density/specific energy than conventional batteries, thus enable the driving range of an electric vehicle comparable to a gasoline vehicle. However, making Li-air batteries rechargeable presents significant challenges, mostly related with materials. Herein, we discuss the key factors that influence the rechargeability of Li-air batteries with a focus on nonaqueous system. The status and materials challenges for nonaqueous rechargeable Li-air batteries are reviewed. These include electrolytes, cathode (electocatalysts), lithium metal anodes, and oxygen-selective membranes (oxygen supply from air). The perspective of rechargeable Li-air batteries is provided.

Anisotropic Compton Scattering in LiF  

Science Journals Connector (OSTI)

Both experimental measurement and theoretical calculations of the Compton profiles of LiF indicate a significant anisotropy in the electron momentum distribution whereas published x-ray structure-factor data indicate a lack of anisotropy in the charge density. In this paper we show that momentum distributions can be orders of magnitude more sensitive to anisotropy in the electron distributions than x-ray structure factors, at least in materials where the overlap of the wave functions is small.

Optical properties of LiF  

Science Journals Connector (OSTI)

In this paper, we examine the optical properties of LiF. The fundamental calculations performed are a self-consistent Hartree-Fock band-structure calculation. As has been found previously, such a calculation has substantial errors when compared with experiment. Correlation corrections are needed and are included by means of the electronic-polaron method. The usual electronic polaron is extended to include short-range polarization corrections which the usual model neglects but which are peculiarly large for LiF. The energy bands are evaluated directly by the linear-combination-of-local-basis-functions method along with the crystal wave functions for 89 points in the irreducible wedge of the first Brillouin zone. Using these results and the Lemann-Taut interpolation scheme the density of states, the joint density of states, and the imaginary part of the dielectric function are computed. These results which neglect the formation of excitons and "plasmons" are in poor agreement with experiment. The effect of the exciton formation is included by a Koster-Slater one-bandone-site calculation. We find that the inclusion of exciton effects substantially improves the level of agreement with experiment. This is in direct contrast with recent work of Menzel et al. in which energy-band theory alone is found to account for the optical properties of LiF. This disagreement is discussed in detail.

Characterization of Li-rich xLi2MnO3(1?x)Li[MnyNizCo1?y?z]O2 as cathode active materials for Li-ion batteries  

Science Journals Connector (OSTI)

Abstract We have investigated the crystallographical, morphological, and electrochemical behaviors of synthesized four different compositions of xLi2MnO3(1?x)Li[MnyNizCo1?y?z]O2 cathode active materials using X-ray diffractometer (XRD), field emission scanning electron microscope (FE-SEM), and galvanostatic cycler. The four different compositions of cathode active materials demonstratea commonly angular shape of primary particles, but agglomerated spherical shape in appearance. All the attempted compositions of xLi2MnO3(1?x)Li[MnyNizCo1?y?z]O2 cathodes deliver a specific discharge capacity of between 220 and 242mAh/g at room temperature when cycled between 2.5 and 4.6V versus Li/Li+ at C/10 rate.

Conductivity and dielectric constants of LiD  

Science Journals Connector (OSTI)

The dielectric constant of LiD has been measured in the frequency region 5-500 kHz at different temperatures up to 340 C. Compared to the results of other workers, the LiD conductivity curves are found to be displaced slightly to lower values than those of LiH. Furthermore, it is also proved that the high ac-conductivity values found by other workers at low temperature in the case of LiH correspond not to true conductivity but are caused by reorientation of complexes. Activation energies corresponding to the motion of a free cation vacancy or the reorientation of complexes have been determined.

Impedance behavior of the LiMn2O4/LiPF6-DMC-EC interface during cycling  

SciTech Connect

Room temperature impedance measurements of the LiMn2O4/LiPF6-EC-DMC interface have been used to identify a previously unreported step in the formation of the SEI layer on this cathode. The low frequency impedance and potential of pure dense LiMn2O4 films was found to depend logarithmically on time in the end-of-discharge (EOD) state. The rate of the impedance rise decreased with Mn3+ content. The increased impedance was removed by oxidation of the film to 4.5 V vs. Li/Li+. The observations are consistent with a reversible disproportionation of part of the LiMn2O4 into Li2Mn2O4 and l-Mn2O4. Analyses of cyclic voltammograms and impedance spectra at intervals during constant current cycling of the LiMn2O4 films suggest that Li2Mn2O4 on the surface also plays a major role in the capacity fade.

Compton profiles of LiF  

Science Journals Connector (OSTI)

?-ray Compton profiles of LiF with the scattering vector along the , , and axes are reported. Both the absolute profiles and their anisotropy are derived from a tight-binding model and compared with experiments. The overall agreement between theory and experiment is found to be satisfactory for all three directions. Recent calculations of Euwema et al. are compared with the present work and found to predict incorrect anisotropies, particularly at small momentum transfers. It is also shown that momentum distributions can be orders of magnitude more sensitive to anisotropy in the electron distributions than x-ray structure factors, at least in materials where overlap of the wave functions is small.

Cross Relaxation in LiF  

Science Journals Connector (OSTI)

A combined experimental and theoretical study of cross relaxation in LiF has been carried out. In agreement with theory, the cross-relaxation time T21 is observed to be strongly anisotropic and field dependent; at 51.7 gauss it goes from 0.025 second in the [100] direction to 7 seconds in the [111] direction. A frequency distribution function analogous to the line shapes for magnetic absorption is measured down to 10-4 times the maximum value; for most orientations a Gaussian is an excellent approximation to it.

Science Journals Connector (OSTI)

The ionization threshold for crystalline LiF is calculated using a cluster embedded model. The experimental ionization threshold is 9.8 eV; however, previous band and cluster model calculations gave 1415 eV. These earlier calculations used a crystal having a perfect lattice. In the present work, a crystal with lattice defects is introduced. The calculated surface and bulk ionization thresholds are 8.1 and 8.7 eV, respectively, showing good correspondence with experiment. The electron affinity and other band parameters are also studied.

Infrared absorption in LiF polymers and microcrystals  

Science Journals Connector (OSTI)

Infrared absorption spectra are reported for LiF in various stages of aggregation. Starting with monomers and dimers the degree of aggregation is increased to include more complex polymers until the transition is made to microcrystals and finally to bulk. The samples were prepared at helium temperature by the simultaneous condensation of argon and LiF vapor onto a transparent substrate. The argon matrix served the purpose of separating the LiF aggregates without strongly interacting with them. Although LiF vapor contains only monomers and dimers, larger polymers could be formed in the matrix by increasing the concentration of LiF. For concentrations of 2%, more than 20 distinct polymer lines could be seen in the infrared absorption spectrum. At concentrations of 7%, the LiF polymer lines abruptly disappear and a single broad surfacephonon absorption, characteristic of microcrystals, emerges. The surface-phonon frequency slowly shifts with increasing LiF concentration until it coincides with the bulk absorption peak at the long-wavelength transverse-optical phonon frequency. This shift is due to the increased dipolar interaction between microcrystals as they are brought closer together. The infrared absorption spectra of small regular polymers of LiF were calculated and compared with experiment. It appears that the infrared spectrum is much more influenced by the shape of the polymer than by its size.

An attempt to study LiH and Li{sub 2} molecules by high resolution pulsed laser spectroscopy  

SciTech Connect

As we start a program to study alkali hydrides and dimers, we have developed a two-step photoionisation experiment on Li{sub 2} molecules based on the use of an atomic beam and two pulsed dye lasers. The first resonant step which excites the A {sup 1}{sigma}{sub u}{sup +}-X {sup 1}{sigma}{sub g}{sup +}Li{sub 2} dimer systems is a home-made cw-seeded DCM dye laser with a laser linewidth of 55 MHz (FWHM) and near the Fourier transform limit. The second step is a larger width fixed frequency UV laser which allows the photoionisation of the selectively excited molecules. The three {sup 6}Li{sub 2}, {sup 6}Li {sup 7}Li and {sup 7}Li{sub 2} spectra are recorded simultaneously by the use of a doubly-accelerating time-of-flight ion analyser. Comparison between recorded and calculated absorption spectra using Dunham parameters found in the literature is satisfactory. To develop similar pulsed high-resolution investigations in LiH, we have characterized our molecular beam by using the laser induced fluorescence (LIF) technique with a cw blue dye laser. Two Franck-Condon LiH Doppler-free resonances have been observed.

The single-electrode Peltier heats of Li-Al alloy electrodes in LiCl-KCl eutectic system  

SciTech Connect

This paper presents the single-electrode Peltier heat of cathodic (or anodic) reaction of Li-Al alloy electrode in a coexisting phase state, or an intermetallic compound phase state estimated by thermoelectric-power measurement. The thermoelectric-power measurements of Li-Al alloys in various coexisting phase states were carried out with both potentiometric and potential-sweep methods in the LiCl-KCl eutectic system between 673 and 843 K. The values of the thermoelectric power of Li-Al alloys calculated by using thermodynamic literature data were in good agreement with those obtained by experiment. The single-electrode Peltier heat changes drastically with change of its phase state, and it was found that the formation reactions of [beta] (Li[sub 0.5]Al[sub 0.5]) and [gamma] (Li[sub 0.6]Al[sub 0.4]) phases are exothermic, and those of liquid phase from [beta] and [gamma] phase are endothermic. The single-electrode Peltier heat for the cathodic formation reaction of Li-Al alloy in intermetallic compound [gamma] phase is estimated to be exothermic by using the measured values of thermoelectric powers of Li-Al alloys in ([beta] + [gamma]) and ([gamma] + liq.) regions.

The desiccant dehumidifier removes the latent load by absorbing moisture from the air, and the sensible load is removed by the absorption chiller. The desiccant dehumidifier is coupled to a regenerator and the desiccant in the regenerator is heated by solar heated hot water to drive the moisture therefrom before being fed back to the dehumidifier. The heat of vaporization expended in the desiccant regenerator is recovered and used to partially preheat the driving fluid of the absorption chiller, thus substantially improving the overall COP of the hybrid system.

Effects of Nonaqueous Electrolytes on Primary Li-Air Batteries  

SciTech Connect

The effects of nonaqueous electrolytes on the performance of primary Li-air batteries operated in dry air environment have been investigated. Organic solvents with low volatility and low moisture absorption are necessary to minimize the change of electrolyte compositions and the reaction between Li anode and water during the discharge process. The polarity of aprotic solvents outweighs the viscosity, ion conductivity and oxygen solubility on the performance of Li-air batteries once these latter properties attain certain reasonable level, because the solvent polarity significantly affects the number of tri-phase regions formed by oxygen, electrolyte, and active carbons (with catalyst) in the air electrode. The most feasible electrolyte formulation is the system of LiTFSI in PC/EC mixtures, whose performance is relatively insensitive to PC/EC ratio and salt concentration. The quantity of such electrolyte added to a Li-air cell has notably effects on the discharge performance of the Li-air battery as well, and a maximum in capacity is observed as a function of electrolyte amount. The coordination effect from the additives or co-solvents [tris(pentafluorophenyl)borane and crown ethers in this study] also greatly affects the discharge performance of a Li-air battery.

Threshold for Potential Sputtering of LiF  

Science Journals Connector (OSTI)

We have measured total sputtering yields for impact of slow ( ?100 eV) singly and doubly charged ions on LiF. The minimum potential energy necessary to induce potential sputtering (PS) from LiF was determined to be about 10 eV. This threshold coincides with the energy necessary to produce a cold hole in the valence band of LiF by resonant neutralization. This allows the first unambiguous identification of PS induced by cold holes. Further stepwise increase of the sputtering yield with higher projectile potential energies provides evidence for additional defect-mediated sputtering mechanisms operative in alkali halides.

Stability of polymer binders in Li-O2 batteries  

SciTech Connect

A number of polymers with various chemical structures were studied as binders for air electrodes in Li-O2 batteries. The nature of the polymer significantly affects the binding properties in the carbon electrodes thus altering the discharge performance of Li-O2 batteries. Stability of polymers to the aggressive reduced oxygen species generated during discharge was tested by ball milling them with KO2 and Li2O2, respectively. Most of the polymers decomposed under these conditions and mechanisms of the decompositions are proposed for some of the polymers. Polyethylene was found to have excellent stability and is suggested as robust binder for air electrodes in Li-O2 batteries.

Methods and preliminary measurement results of liquid Li wettability  

SciTech Connect

A test of lithium wettability was performed in high vacuum (< 3 10{sup ?4} Pa). High magnification images of Li droplets on stainless steel substrates were produced and processed using the MATLAB{sup } program to obtain clear image edge points. In contrast to the more standard ?/2 or polynomial fitting methods, ellipse fitting of the complete Li droplet shape resulted in reliable contact angle measurements over a wide range of contact angles. Using the ellipse fitting method, it was observed that the contact angle of a liquid Li droplet on a stainless steel substrate gradually decreased with increasing substrate temperature. The critical wetting temperature of liquid Li on stainless steel was observed to be about 290?C.

Complete fusion in 7Li+144,152Sm reactions  

Science Journals Connector (OSTI)

Complete fusion cross sections for 7Li+144,152Sm reactions have been measured at energies around the Coulomb barrier by offline ?-counting technique. Measured cross sections for the above two reactions are found to be similar at energies well above the Coulomb barrier, however, at sub-barrier energies the cross sections for the 7Li+152Sm system are much higher compared to the 7Li+144Sm system, manifesting the effect of target deformation. Cross sections for the present reactions at above-barrier energies are found to be larger than previously measured reactions involving 6Li projectile with the same targets, possibly due to smaller breakup probability of 7Li than 6Li. Coupled-channels calculations show that the experimental fusion cross sections for both the systems are enhanced at subbarrier energies and suppressed at above-barrier energies compared to the respective one-dimensional barrier penetration model predictions. The calculations by different models show that the measured complete fusion cross sections at above-barrier energies are suppressed up to ?25% compared to the theoretical predictions. It also reveals that a large part of the suppression could be due to inelastic and transfer coupling.

The partially reversible formation of Li-metal particles on a solid Li electrolyte: applications toward nanobatteries  

SciTech Connect

The feasibility of large-scale implementation of Li-air batteries (LABs) hinges on understanding the thermodynamic and kinetic factors that control charge-discharge rates, efficiency and life times. Here, the kinetics of bias-induced reactions is explored locally on the surface of Li-ion conductive glass ceramics, a preferred electrolyte for LABs, using direct current-voltage and strain spectroscopies. Above a critical bias, particle growth kinetics were found to be linear in both the bias and time domains. Partial reversibility was observed for Li particles as evidenced by the presence of anodic peaks following the Li{sup +} reduction, as well an associated reduction in particle height. The degree of reversibility was highest for the smallest particles formed. These observations thus suggest the possibility of producing nanobatteries with an active anode volume of the order of 0.1 al.

Reaction Mechanisms in the Li3AlH6/LiBH4 and Al/LiBH4 Systems for Reversible Hydrogen Storage. Part 1: H capacity and Role of Al  

SciTech Connect

Lithium-based complex hydrides, including lithium aluminum hydrides (LiAlH4, Li3AlH6) and lithium borohydride (LiBH4), are some of the most attractive materials for hydrogen storage due to their high hydrogen contents. In the present work, we investigated the hydrogen storage properties of combined systems of Li3AlH6-LiBH4 and Al-LiBH4, both of which exhibit favorable hydrogen storage properties owing to the formation of AlB2 during dehydrogenation. TGA data showed that TiCl3-doped Li3AlH6/2LiBH4 and 0.5Al/LiBH4 release ~ 8.8 and ~ 8.4 wt.% H2, respectively, with ~ 3.8 and ~ 5.8 wt.% release after rehydrogenation of the dehydrogenation product. XRD results identified LiH and AlB2 phases in the dehydrogenated products, which has suggested a mechanism by which Al contributes to the remarkable improvement of the reversible storage properties of LiBH4 in terms of the temperature and pressure for H2 release/uptake.

F Band in Isotopically Enriched LiF  

Science Journals Connector (OSTI)

The effect of isotopic composition on the optical obsorption spectrum of the F center in LiF has been investigated. The results of measurements on single crystals of x-ray irradiated Li6F (almost 96% lithium-6) and Li7F (almost 100% lithium-7) indicate that the average F-band width at half-maximum in the former is larger by about 3% at liquid-helium temperature, and by about 1% at room temperature. Theory shows that the half-widths in the two isotopic forms vary inversely as the fourth root of the mass of the alkali ions at low temperature, and as the temperature is increased the predicted half-width difference monotonically decreases to zero. The predicted half-width difference at low temperatures is about 4%, and at room temperature about 1%, both in reasonable agreement with experiment. At both room and liquid-helium temperatures the position of the F-band maximum in Li7F is slightly displaced to higher energy than in Li6F. The peak-position shift is in approximate agreement with the contributions arising from the difference in alkali mass and lattice constant of the two crystals as estimated at low temperature.

High Performance Cathodes for Li-Air Batteries  

SciTech Connect

The overall objective of this project was to develop and fabricate a multifunctional cathode with high activities in acidic electrolytes for the oxygen reduction and evolution reactions for Li-air batteries. It should enable the development of Li-air batteries that operate on hybrid electrolytes, with acidic catholytes in particular. The use of hybrid electrolytes eliminates the problems of lithium reaction with water and of lithium oxide deposition in the cathode with sole organic electrolytes. The use of acid electrolytes can eliminate carbonate formation inside the cathode, making air breathing Li-air batteries viable. The tasks of the project were focused on developing hierarchical cathode structures and bifunctional catalysts. Development and testing of a prototype hybrid Li-air battery were also conducted. We succeeded in developing a hierarchical cathode structure and an effective bifunctional catalyst. We accomplished integrating the cathode with existing anode technologies and made a pouch prototype Li-air battery using sulfuric acid as catholyte. The battery cathodes contain a nanoscale multilayer structure made with carbon nanotubes and nanofibers. The structure was demonstrated to improve battery performance substantially. The bifunctional catalyst developed contains a conductive oxide support with ultra-low loading of platinum and iridium oxides. The work performed in this project has been documented in seven peer reviewed journal publications, five conference presentations, and filing of two U.S. patents. Technical details have been documented in the quarterly reports to DOE during the course of the project.

The Decays of Luminescent KBr and LiF  

Science Journals Connector (OSTI)

A photo-multiplier, together with electronic pulse techniques, has been used to investigate the luminescent decay of KBr and LiF after irradiation with x-rays, at various temperatures. Decay curves plotted on a log-log scale are linear for KBr at 21C and for LiF at 21C and 0C, with an average slope of 1.2. The curves for KBr at 0C and the temperature of dry ice and acetone have linear upper and lower parts, connected by an intermediate curved part. It is suggested that the upper linear part is due to the decay of F? centers, and the lower part to the decay of F centers. The emission spectrum of KBr consists of 2 bands, a strong one centered at 4550A and a weaker one at 5300A, while that of LiF extends into the ultraviolet below 3000A.

Electronic and structural properties of LiBeH3  

Science Journals Connector (OSTI)

In a recent paper, A. W. Overhauser Phys. Rev. B 35, 411 1987 suggested that LiBeH3 could be a metal with a very large electron density, in the range attributed to the metallic phases of hydrogen, and that it could share the properties often envisioned for metallic hydrogen, including high-temperature superconductivity. Band-structure and total-energy calculations for LiBeH3 suggest that it is an ionicly bonded insulator with only half the density assumed by Overhauser. It is therefore a poor candidate for a metal with a large electron density.

Thermodynamic properties of a Li-Al alloy in the two-phase ({alpha}Al + {beta}LiAl), ({beta}LiAl + {gamma}Li{sub 3}Al{sub 2}), and ({gamma}Li{sub 3}Al{sub 2} + liquid) regions, and in the single {beta}LiAl phase region were determined from electromotive force measurements in a LiCl-KCl eutectic melt at temperatures from 650 to 76f0 K. From the obtained thermodynamic properties, the single-electrode Peltier heat of a Li-Al alloy electrode was evaluated as a function of the alloy composition. It turned out that the single-electrode Peltier heat of a Li-Al alloy electrode exhibits discontinuities at the compositions of coexisting-single phase boundaries. The change of the single-electrode Peltier heat on a phase boundary was interpreted thermodynamically and was found to follow from thermodynamic data for the single phases and the phase diagram data.

Magnetism reflectometer study shows LiF layers improve efficiency in spin valve devices  

SciTech Connect

New, more efficient materials for spin valves - a device used in magnetic sensors, random access memories, and hard disk drives - may be on the way based on research using the magnetism reflectometer at Oak Ridge National Laboratory (ORNL). Spin valve devices work by means of two or more conducting magnetic material layers that alternate their electrical resistance depending on the layers alignment. Giant magnetoresistance is a quantum mechanical effect first observed in thin film structures about 20 years ago. The effect is observed as a significant change in electrical resistance, depending on whether the magnetization of adjacent ferromagnetic layers is in a parallel or an antiparallel magnetic alignment. 'What we are doing here is developing new materials. The search for new materials suitable for injecting and transferring carriers with a preferential spin orientation is most important for the development of spintronics,' said Valeria Lauter, lead instrument scientist on the magnetism reflectometer at the Spallation Neutron Source (SNS), who collaborated on the experiment. The researchers discovered that the conductivity of such materials is improved when an organic polymer semiconductor layer is placed between the magnetic materials. Organic semiconductors are now the material of choice for future spin valve devices because they preserve spin coherence over longer times and distances than conventional semiconductors. While research into spin valves has been ongoing, research into organic semiconductors is recent. Previous research has shown that a 'conductivity mismatch' exists in spin valve systems in which ferromagnetic metal electrodes interface with such organic semiconductors as Alq3 ({pi}-conjugated molecule tris(8-hydroxy-quinoline) aluminium). This mismatch limits the efficient injection of the electrons from the electrodes at the interface with the semiconductor material. However, lithium fluoride (LiF), commonly used in light-emitting diodes, has been found to enhance the injection of electrons through the semiconductor. Researchers from the University of Alabama and ORNL used polarized neutrons at the magnetism reflectometer at SNS to investigate the electronic, magnetic, and structural properties of the electrodes in a novel system. In this system, the magnetic layers cobalt and Ni{sub 80}Fe{sub 20} are interfaced with spacer layers composed of the organic semiconductor Alq3. A coupling layer of LiF is inserted to separate the magnetized layers from the semiconductor. 'ALQ3 is an organic semiconductor material,' said Lauter. 'Normally in these systems a first magnetic layer is grown on a hard substrate so that one can get the controlled magnetic parameters. Then you grow the organic semiconductor layer, followed by another magnetic material layer, such as cobalt.' In addition to determining the effect of the LiF layers on the efficiency of the electron injection, the researchers wanted to determine the magnetic properties of the cobalt and Ni{sub 80}Fe{sub 20} as well as the interfacial properties: whether there is interdiffusion of cobalt through the LiF layer to the semiconductor, for example. The researchers used polarized neutrons at beam line 4A to probe the entire, layer-by-layer assembly of the system. 'Reflectometry with polarized neutrons is a perfect method to study thin magnetic films,' Lauter said. 'These thin films - if you put one on a substrate, you see it just like a mirror. However, this mirror has a very complicated internal multilayer structure. The neutrons look inside this complicated structure and characterize each and every interface. Due to the depth sensitivity of the method, we measure the structural and magnetic properties of each layer with the resolution of 0.5 nm. The neutron scattering results found that inserting LiF as a barrier significantly improves the quality of the interface, increasing the injection of electrons from the magnetic layer through the organic semiconductor in the spin valve and enhancing the overall properties of the system. In related work the magneti

The Stability of Organic Solvents and Carbon Electrode in Nonaqueous Li-O2 Batteries  

SciTech Connect

The effect of different kinds of aprotic organic solvents on the discharge performance and discharge products in Li-O2 batteries was systematically investigated. The discharge products deposited in air cathodes were analyzed by X-ray diffraction, in situ gas chromatography/mass spectroscopy and X-ray photoelectron spectroscopy. We found that a significant amount of Li2O2 can be formed in glyme-based electrolytes during the discharge process, while only small amount of Li2O2 is produced in electrolytes of phosphate, nitrile, ionic liquid and sulfoxide. However, in all the seven types of solvent systems we studied, Li2CO3 and LiF were still formed as byproducts whose compositions are strongly related to the solvents. Li2CO3 is produced not from the carbon air electrode but from oxidation and decomposition of the solvent as we verified by using a 13C-labeled carbon electrode and the solid-state 13C-MAS NMR technique. The formation of Li2CO3 and LiF during discharge will greatly reduce the Coulombic efficiency and cycle life of the Li-air batteries. Therefore, better electrolytes that can ensure the formation of Li2O2 but minimize other reaction products formed on air electrodes of Li-air batteries need to be further investigated.

Efficient chemical regeneration of LiBH4NH3 spent fuel for hydrogen storage  

Science Journals Connector (OSTI)

Abstract The absence of an efficient method for the regeneration of ammine metal borohydrides (M(BH4)nxNH3, AMBs) from their dehydrogenated products has hindered their potential application as hydrogen storage materials. In this paper, we demonstrate a high-yield chemical regeneration of LiBH4NH3 based on a three step process (digestion (H+ addition), reduction (H? addition), and ammonia complexation) at ambient temperature. Our results demonstrated that LiBN polymer was digested by methanol to form LiB(OCH3)4, which can be converted into LiBH4 by using LiAlH4 in the reduction process. The generation of LiBH4NH3 in ammonia complexion step was achieved by exposing the obtained LiBH4 in an ammonia atmosphere.

Fusion of Li and C and a search for entrance channel limitations to fusion cross sections  

Science Journals Connector (OSTI)

Excitation functions have been measured for reaction products from the Li6 and Li7 induced reactions Li6+C12, Li6+C13, Li7+C12, and Li7+C13. These data cover the energy range from Elab=9to36 MeV. It was found that the maximum fusion cross sections for these reactions are 780 and 770 mb for the Li6+C12 and Li6+C13, respectively, and 960 and 930 mb for the Li7+C12 and Li7+C13, respectively. The relative uncertainties for these maximum fusion cross sections are about 5%. Comparisons between optical model calculations of the total reaction cross sections and the measured fusion cross sections indicate that total fusion cross sections are substantially smaller than the total reaction cross sections for all four reactions at all energies. For each of the four entrance channels, energy and angular distributions have been measured at four energies for individual mass groups between A=9and19 u. Most of these products appear to be evaporation residues. The critical angular momenta deduced from the experimental fusion cross sections are discussed in terms of entrance channel and compound nucleus limitation models for compound nucleus formation. The individual mass groups are discussed in terms of systematics for evaporation residues.NUCLEAR REACTIONS Li6+C12, ELi6=10to36 MeV; Li6+C13, ELi6=9.23to35.08 MeV; Li7+C12, ELi7=10to38 MeV; Li7+C13, ELi7=10to34 MeV, measured d2?d? dE for reaction products from A=9to19.

LiMn2O4 cathode doped with excess lithium and synthesized by co-precipitation for Li-ion batteries  

Science Journals Connector (OSTI)

LiMn2O4 exhibits lower cost, acceptable environmental characteristics, and better safety properties than other positive-electrode (cathode) materials for lithium-ion batteries. In this study, excess Li doped Li1+xMn2O4 is synthesized by a well-mixed co-precipitation method with LiOH utilized as both the reactant and co-precipitation agent. The precursor is calcined for various heating times and temperatures to form a fine powder of a single spinel phase with different particle sizes, size distributions, and morphology. The minimum heating temperature is around 400C. For short heating periods, Mn2O3 impurity is observed, but disappears after longer heating times. The average particle size is in the range 28?m for powders calcined between 700 and 870C. The lattice parameter increases with increase in heating temperature. The electrochemical behavior of LiMn2O4 powder is examined by using test cells which consist of a cathode, a metallic lithium anode, and an electrolyte of 1M LiPF6 in a 1:1 (volume ratio) mixture of ethylene carbonate (EC) and dimethyl carbonate (DMC). Cells with cathodes of LiMn2O4, Li1.08Mn2O4 and Li1.1Mn2O4 give a capacity of 85, 109 and 126mAhg?1, respectively. The introduction of excess Li in LiMn2O4 apparently increases the capacity, and decreases significantly the rate of capacity degradation on chargedischarge cycling.

Calculations for methane scattering from LiF(001)  

Science Journals Connector (OSTI)

Calculations are presented for the scattering of CH4 molecules from a LiF(001) surface. The theory utilized is a mixed classical-quantum model that includes energy and momentum transfers between the surface and projectile for translational and rotational motions as well as internal mode excitation of the projectile molecule. The translation and rotation motions, including multiphonon excitations with the surface, are treated with classical dynamics. Internal vibrational mode excitation of the molecules is treated quantum mechanically with extension to arbitrary numbers of modes and arbitrary excitation quantum numbers. The results of calculations are compared with recent high-precision measurements of the scattering of CH4 molecules from clean, ordered LiF(001). The calculated results for energy-resolved spectra and for the angular distributions are in good agreement with experiment.

Auger spectrum of the LiF molecule  

Science Journals Connector (OSTI)

The Auger spectrum of LiF vapor has been measured in the energy region 600-680 eV by means of electron-beam excitation. The assignment of the peak structure is based on theoretical ab initio calculations with the use of the multiconfigurational complete-active-space self-consistent-field method and by comparison with the corresponding spectra of the neon atom and the hydrogen fluoride molecule.

Interaction between Thermal Phonons and Dislocations in LiF  

Science Journals Connector (OSTI)

Thermal conductivity measurements on deformed LiF crystals from 0.04 to 0.8 K have indicated a strong polarization- and frequency-dependent dynamic scattering of thermal phonons by mobile dislocations. Heat-pulse experiments at 3.6 K have verified both the strength and polarization dependence of the scattering mechanism. The scattering of thermal phonons by sessile dislocations was too weak to be detected.

Predictive Models of Li-ion Battery Lifetime (Presentation)  

SciTech Connect

Predictive models of Li-ion battery reliability must consider a multiplicity of electrochemical, thermal and mechanical degradation modes experienced by batteries in application environments. Complicating matters, Li-ion batteries can experience several path dependent degradation trajectories dependent on storage and cycling history of the application environment. Rates of degradation are controlled by factors such as temperature history, electrochemical operating window, and charge/discharge rate. Lacking accurate models and tests, lifetime uncertainty must be absorbed by overdesign and warranty costs. Degradation models are needed that predict lifetime more accurately and with less test data. Models should also provide engineering feedback for next generation battery designs. This presentation reviews both multi-dimensional physical models and simpler, lumped surrogate models of battery electrochemical and mechanical degradation. Models are compared with cell- and pack-level aging data from commercial Li-ion chemistries. The analysis elucidates the relative importance of electrochemical and mechanical stress-induced degradation mechanisms in real-world operating environments. Opportunities for extending the lifetime of commercial battery systems are explored.

Revisit Carbon/Sulfur Composite for Li-S Batteries  

SciTech Connect

To correlate the carbon properties e.g. surface area and porous structure, with the electrochemical behaviors of carbon/sulfur (C/S) composite cathodes for lithium-sulfur (Li-S) batteries, four different carbon frameworks including Ketjen Black (KB, high surface area and porous), Graphene (high surface area and nonporous), Acetylene Black (AB, low surface area and nonporous) and Hollow Carbon Nano Sphere (HCNS, low surface area and porous) are employed to immobilize sulfur (80 wt.%). It has been revealed that high surface area of carbon improves the utilization rate of active sulfur and decreases the real current density during the electrochemical reactions. Accordingly, increased reversible capacities and reduced polarization are observed for high surface area carbon hosts such as KB/S and graphene/S composites. The porous structure of KB or HCNS matrix promotes the long-term cycling stability of C/S composites but only at relatively low rate (0.2 C). Once the current density increases, the pore effect completely disappears and all Li-S batteries show similar trend of capacity degradation regardless of the different carbon hosts used in the cathodes. The reason has been assigned to the formation of reduced amount of irreversible Li2S on the cathode as well as shortened time for polysulfides to transport towards lithium anode at elevated current densities. This work provides valuable information for predictive selection on carbon materials to construct C/S composite for practical applications from the electrochemical point of view.

High Capacity Pouch-Type Li-air Batteries  

SciTech Connect

The pouch-type Li-air batteries operated in ambient condition are reported in this work. The battery used a heat sealable plastic membrane as package material, O2 diffusion membrane and moisture barrier. The large variation in internal resistance of the batteries is minimized by a modified separator which can bind the cell stack together. The cells using the modified separators show improved and repeatable discharge performances. It is also found that addition of about 20% of 1,2-dimethoxyethane (DME) in PC:EC (1:1) based electrolyte solvent improves can improve the wetability of carbon electrode and the discharge capacities of Li-air batteries, but further increase in DME amount lead to a decreased capacity due to increase electrolyte loss during discharge process. The pouch-type Li-air batteries with the modified separator and optimized electrolyte has demonstrated a specific capacity of 2711 mAh g-1 based on carbon and a specific energy of 344 Wh kg-1 based on the complete batteries including package.

Development of Li+ alumino-silicate ion source  

SciTech Connect

To uniformly heat targets to electron-volt temperatures for the study of warm dense matter, one strategy is to deposit most of the ion energy at the peak of energy loss (dE/dx) with a low (E< 5 MeV) kinetic energy beam and a thin target[1]. Lower mass ions have a peak dE/dx at a lower kinetic energy. To this end, a small lithium (Li+) alumino-silicate source has been fabricated, and its emission limit has been measured. These surface ionization sources are heated to 1000-1150 C where they preferentially emit singly ionized alkali ions. Alumino-silicates sources of K+ and Cs+ have been used extensively in beam experiments, but there are additional challenges for the preparation of high-quality Li+ sources: There are tighter tolerances in preparing and sintering the alumino-silicate to the substrate to produce an emitter that gives uniform ion emission, sufficient current density and low beam emittance. We report on recent measurements ofhigh ( up to 35 mA/cm2) current density from a Li+ source. Ion species identification of possible contaminants is being verified with a Wien (E x B) filter, and via time-of-flight.

A Simultaneous Solution to the ^6Li and ^7Li Big Bang Nucleosynthesis Problems from a Long-Lived Negatively-Charged Leptonic Particle  

E-Print Network (OSTI)

The $^6$Li abundance observed in metal poor halo stars exhibits a plateau similar to that for $^7$Li suggesting a primordial origin. However, the observed abundance of $^6$Li is a factor of $10^3$ larger and that of $^7$Li is a factor of 3 lower than the abundances predicted in the standard big bang when the baryon-to-photon ratio is fixed by WMAP. Here we show that both of these abundance anomalies can be explained by the existence of a long-lived massive, negatively-charged leptonic particle during nucleosynthesis. Such particles would capture onto the synthesized nuclei thereby reducing the reaction Coulomb barriers and opening new transfer reaction possibilities, and catalyzing a second round of big bang nucleosynthesis. This novel solution to both of the Li problems can be achieved with or without the additional effects of stellar destruction.

On LiF:Mg,Cu,P and LiF:Mg,Ti phosphors high & ultra-high dose features  

E-Print Network (OSTI)

LiF:Mg,Ti and LiF:Mg,Cu,P are well known thermoluminescence (TL) dosimetry materials since many years. A few years ago their properties seemed well known and it was widely believed that they are not suitable for the measurement of doses above the saturation level of the TL signal, which for both materials occur at about 1 kGy. The high-dose high-temperature TL emission of LiF:Mg,Cu,P observed at the IFJ in 2006, which above 30 kGy takes the form of the so-called TL peak B, opened the way to use this material for measuring the dose in the high and ultra-high range, in particular for the monitoring of ionizing radiation around the essential electronic elements of high-energy accelerators, also fission and fusion facilities, as well as for emergency dosimetry. This discovery initiated studies of high and ultra-high dose characteristics of both of these phosphors, which turned out to be significantly different in many aspects. These studies not only strive to refine the method for measuring high doses based on th...

Effect of Li Promoter on titania-supported Rh catalyst for ethanol formation from CO hydrogenation  

SciTech Connect

The addition of 0.10wt% Li to Rh/TiO2 more than doubled the CO conversion for CO hydrogenation while increasing ethanol selectivity. The addition of Li also increases formation of C2 oxygenates at the expense of C1 species, methanol and methane. This is attributed to enhanced dispersion of Rh by Li that appears to reduce dissociation of CO, which previous studies have shown requires large ensembles of Rh atoms on the surface. Li promotion appears to increase the associatively adsorbed CO, allowing for increased H2 chemisorption on the surface compared to the dissociative adsorption of the same number of CO atoms. This increases selectivity to ethanol compared to the unpromoted catalysts. CO-TPD shows more reactive adsorbed CO species on the Li-promoted catalyst. FTIR results suggest that Li promotion alters CO bonding at bridged or interfacial sites and its effect is more structural than electronic.

Dual active material composite cathode structures for Li-ion batteries  

Science Journals Connector (OSTI)

The efficacy of composite Li-ion battery cathodes made by mixing active materials that possessed either high-rate capability or high specific energy was examined. The cathode structures studied contained carbon-coated LiFePO4 and either Li[Li0.17Mn0.58Ni0.25]O2 or LiCoO2. These active materials were arranged using three different electrode geometries: fully intermixed, fully separated, or layered. Discharge rate studies, cycle-life evaluation, and electrochemical impedance spectroscopy studies were conducted using coin cell test structures containing Li-metal anodes. Results indicated that electrode configuration was correlated to rate capability and degree of polarization if there was a large differential between the rate capabilities of the two active material species.

Vaporization property and crystal structure of lithium metatitanate with excess Li  

Science Journals Connector (OSTI)

Abstract The vaporization property and the crystal structure of lithium metatitanate with excess Li, which has been developed as an advanced tritium breeder, were studied. After synthesizing the lithium metatitanate specimens with Li/Ti=2.02.3 (at mixing of the starting materials), the vaporization properties were investigated by measuring the mass losses during heating at 1173K. The Li excessive specimens indicated higher rates of mass loss than the stoichiometric one during heating as long as excessive lithium atom exists. The crystal structures of stoichiometric and nonstoichiometric lithium metatitanates were discussed with the result of neutron diffraction and the refined structural parameters by Rietveld analysis. The refinement (Rwp=7.98, Rp=5.96 and Re=2.58) suggested that lithium metatitanate with excess Li has ?-Li2TiO3 structure and excess Li atoms exist at unstable sites with the formation of reduced titanium or site vacancies.

Formation Of The Spinel Phase In The Layered Composite Cathode Used In Li-Ion Batteries  

SciTech Connect

Pristine Li-rich layered cathodes, such as Li1.2Ni0.2Mn0.6O2 and Li1.2Ni0.1Mn0.525Co0.175O2, were identified to exist in two different structures: LiMO2 R-3m and Li2MO3 C2/m phases. Upon charge/discharge cycling, both phases gradually transform to the spinel structure. The transition from LiMO2 R-3m to spinel is accomplished through the migration of transition metal ions to the Li site without breaking down the lattice, leading to the formation of mosaic structured spinel grains within the parent particle. In contrast, transition from Li2MO3 C2/m to spinel involves removal of Li+ and O2-, which produces a large lattice strain and leads to the breakdown of the parent lattice and therefore the newly formed spinel grains show random orientation within the same particle. Cracks and pores were also noticed within some particles, which is believed to be the consequence of the breakdown of the lattice and vacancy condensation upon removal of lithium ions. The presently observed structure transition characteristics provide direct reasons for the observed gradual capacity loss and poor rate performance of the layered composite. Ultimately it also provides clues about how to improve the materials structure with potential improved performance.

Impedance studies of the thin film LiMn2O4/electrolyteinterface  

SciTech Connect

Room-temperature impedance measurements of a thin-film LiMn2O4/LiPF6-EC-DMC interface have been used to identify the spontaneous formation Li2Mn2O4 at the interface at room temperature at voltages of 3.7 and higher. The impedance of the LiMn2O4 films exhibited two time constants: at about 14 kHz and 60 to 200 Hz. The high frequency loop is dependent on film morphology and was attributed to the substrate/oxide interface. The low frequency behavior was dependent on both state-of-charge (SOC) and time at a given SOC. At full charge the impedance in this electrolyte was stable at room temperature over several days. At high lithium contents, film OCV and impedance tended to grow logarithmically with time, with lower rates for lower Mn3+ content in the film. The increased impedance was removed by oxidation of the film to 4.5V vs. Li/Li+. The observations are consistent with a reversible disproportionation of part of the LiMn2O4 into Li2Mn2O4 and a lithium-deficient spinel. With extended constant current cycling part of the Li2Mn2O4 degrades to the Mn2O3 and the process is no longer reversible.

Investigation of the Rechargeability of Li-O2 Batteries in Non-aqueous Electrolyte  

SciTech Connect

In order to understand the nature of the limited cycle life and poor energy efficiency associated with the secondary Li-O2 batteries the discharge products of primary Li-O2 cells at different depth of discharge (DOD) are systematically analyzed in this work. It is revealed that if discharged to 2.0 V a small amount of Li2O2 coexist with Li2CO3 and RO-(C=O)-OLi) in alkyl carbonate-based electrolyte. Further discharging the air electrodes to below 2.0 V the amount of Li2CO3 and LiRCO3 increases significantly due to the severe electrolyte decomposition. There is no Li2O detected in this alkyl carbonate electrolyte regardless of DOD. It is also found that the alkyl carbonate based electrolyte begins to decompose at 4.0 V during charging under the combined influences from the high surface area carbon, the nickel metal current collector and the oxygen atmosphere. Accordingly the impedance of the Li-O2 cell continues to increase after each discharge and recharge process indicating a repeated plating of insoluble lithium salts on the carbon surface. Therefore the whole carbon electrode becomes completely insulated only after a few cycles and loses the function of providing active tri-phase regions for the Li-oxygen batteries.

First-Principles Study of Novel Conversion Reactions for High-Capacity Li-Ion Battery Anodes in the Li-Mg-B-N-H System  

SciTech Connect

Anodes for Li-ion batteries are primarily carbon-based due to their low cost and long cycle life. However, improvements to the Li capacity of carbon anodes, LiC{sub 6} in particular, are necessary to obtain a larger energy density. State-of-the-art light-metal hydrides for hydrogen storage applications often contain Li and involve reactions requiring Li transport, and light-metal ionic hydrides are candidates for novel conversion materials. Given a set of known solid-state and gas-phase reactants, we have determined the phase diagram in the Li-Mg-B-N-H system in the grand canonical ensemble, as a function of lithium chemical potential. We present computational results for several new conversion reactions with capacities between 2400 and 4000 mAh g{sup -1} that are thermodynamically favorable and that do not involve gas evolution. We provide experimental evidence for the reaction pathway on delithiation for the compound Li{sub 4}BN{sub 3}H{sub 10}. While the predicted reactions involve multiple steps, the maximum volume increase for these materials on lithium insertion is significantly smaller than that for Si.

Investigation on the Charging Process of Li2O2-Based Air Electrodes in Li-O2 Batteries with Organic Carbonate Electrolytes  

SciTech Connect

The charge processes of Li-O2 batteries were investigated by analyzing the gas evolution by in situ gas chromatography-mass spectroscopy (GC/MS) technique. The mixture of Li2O2/Fe3O4/Super P carbon/polyvinylidene fluoride (PVDF) was used as the starting air electrode material and 1M LiTFSI in carbonate-based solvents was used as electrolyte. It was found that Li2O2 is reactive to 1-methyl-2-pyrrolidinone and PVDF binder used in the electrode preparation. During the 1st charge (up to 4.6 V), O2 was the main component in the gases released. The amount of O2 measured by GC/MS was consistent with the amount of Li2O2 decomposed in the electrochemical process as measured by the charge capacity, indicative of the good chargeability of Li2O2. However, after the cell was discharged to 2.0 V in O2 atmosphere and re-charged to ~ 4.6 V in the second cycle, CO2 was dominant in the released gases. Further analysis of the discharged air electrode by X-ray diffraction and Fourier transform infrared spectroscopy indicated that lithium-containing carbonate species (lithium alkyl carbonate and/or Li2CO3) were the main reaction products. Therefore, compatible electrolyte and electrodes as well as the electrode preparation procedures need to be developed for long term operation of rechargeable Li-O2 or Li-air batteries.

Ballistic-phonon propagation in LiF  

Science Journals Connector (OSTI)

The interaction between high-frequency ballistic phonons and mass defects in LiF of natural isotopic composition has been studied with the use of a heat-pulse technique. Studies were made as a function of input power for samples of various length oriented along the [111] direction. The results indicate that surface imperfections have a profound effect on the transmission of high-frequency phonons. The experiments on suitably prepared surfaces yield a phonon scattering rate which is in excellent agreement with theoretical predictions and thermal conductivity measurements.

LiWall Fusion - The New Concept of Magnetic Fusion  

SciTech Connect

Utilization of the outstanding abilities of a liquid lithium layer in pumping hydrogen isotopes leads to a new approach to magnetic fusion, called the LiWall Fusion. It relies on innovative plasma regimes with low edge density and high temperature. The approach combines fueling the plasma by neutral injection beams with the best possible elimination of outside neutral gas sources, which cools down the plasma edge. Prevention of cooling the plasma edge suppresses the dominant, temperature gradient related turbulence in the core. Such an approach is much more suitable for controlled fusion than the present practice, relying on high heating power for compensating essentially unlimited turbulent energy losses.

Physical properties of Li ion conducting polyphosphazene based polymer electrolytes  

SciTech Connect

We report a systematic study of the transport properties and the underlying physical chemistry of some polyphosphazene (PPhz)-based polymer electrolytes. We synthesized MEEP and variants which employed mixed combinations of different length oxyethylene side-chains. We compare the conductivity and ion-ion interactions in polymer electrolytes obtained with lithium triflate and lithium bis(trifluoromethanesulfonyl)imide (TFSI) salts added to the polymer. The combination of the lithium imide salt and MEEP yields a maximum conductivity of 8 x 10{sup -5} {Omega}{sup -1} cm{sup -1} at room temperature at a salt loading of 8 monomers per lithium. In one of the mixed side-chain variations, a maximum conductivity of 2 x 10{sup -4} {Omega}{sup -1} cm{sup -1} was measured at the same molar ratio. Raman spectral analysis shows some ion aggregation and some polymer - ion interactions in the PPhz-LiTFSI case but much less than observed with Li CF{sub 3}SO{sub 3}. A sharp increase in the Tg as salt is added corresponds to concentrations above which the conductivity significantly decreases and ion associations appear.

Study on generating of thermal neutron scattering cross sections for LiH  

SciTech Connect

LiH is designated as a promising moderator and shielding material because of its low density, high melting point and large fraction of H atoms. However, lack of the thermal neutron cross sections of LiH makes numerical calculation deviate from experimental data to some extent. As a result, it is necessary to study LiH thermal kernel effect. The phonon property of LiH has been investigated by first-principles calculations using the plane-wave pseudo potential method with CASTEP code. The scattering law and the thermal neutron scattering cross sections for Li and H have been generated using this distribution. The results have been compared with zirconium hydride data. The GASKET and NJOY/LEAPR codes have been used in the calculation of scattering law, whose results have been compared with the reference; the discrepancy mainly comes from phonon spectrums and its expansion. LEAPR had the capability to compute scattering through larger energy and momentum transfers than GASKET did. By studying LiH phonon spectrum and constructing the model of LiH thermal kernel and scattering matrix, the ACE format LiH thermal neutron cross sections for MCNP software could be made and used for reactor Neutronics calculation.

Ultra-high hydrogen storage capacity of Li-decorated graphyne: A first-principles prediction  

SciTech Connect

Graphyne, consisting of sp- and sp{sup 2}-hybridized carbon atoms, is a new member of carbon allotropes which has a natural porous structure. Here, we report our first-principles calculations on the possibility of Li-decorated graphyne as a hydrogen storage medium. We predict that Li-doping significantly enhances the hydrogen storage ability of graphyne compared to that of pristine graphyne, which can be attributed to the polarization of H{sub 2} molecules induced by the charge transfer from Li atoms to graphyne. The favorite H{sub 2} molecules adsorption configurations on a single side and on both sides of a Li-decorated graphyne layer are determined. When Li atoms are adsorbed on one side of graphyne, each Li can bind four H{sub 2} molecules, corresponding to a hydrogen storage capacity of 9.26 wt. %. The hydrogen storage capacity can be further improved to 15.15 wt. % as graphyne is decorated by Li atoms on both sides, with an optimal average binding energy of 0.226 eV/H{sub 2}. The results show that the Li-decorated graphyne can serve as a high capacity hydrogen storage medium.

A LiCoMnO4 (5V spinel) material has been synthesized by annealing a solgel precursor utilizing lithium acetate, cobalt acetate, manganese acetate, and citric acid. The as-prepared sample has been determined to be LiCo1.09Mn0.91O4 via inductive coupled plasma-atomic emission spectroscopy. The deviation of the molar ratio of Co/Mn from 1:1 is designed to minimize the amount of LiMn2O4 impurity in our sample. The produced spinel material possesses an initial discharge capacity of 87.1mAhg?1 with two voltage plateaus at 5.1 and 4.9V. The LiCo1.09Mn0.91O4 cathode has been assembled with a Li4Ti5O12 anode to form a full-cell which delivered a discharge capacity of 131.2mAhg?1, centered at 3.2V. It is of great interest that despite the low coulombic efficiency of the full-cell, it shows good cyclic performance. In addition, The LiCo1.09Mn0.91O4/Li4Ti5O12 cell shows an excellent rate capability, delivering a capacity of 84.2mAhg?1, corresponding to a high power density of 4.70kWkg?1 at the current density of 1700mAg?1.

Magnetic phase diagram of magnetoelectric LiMnPO4  

SciTech Connect

The nature of the spin-flop (SF) transition in the magnetoelectric quasi-2D Heisenberg system LiMnPO4 is studied in fields applied along the a axis. A refinement of the magnetic structure using neutron diffraction data in the SF phase reveals that the spins reorient from being parallel to the a axis to be nearly along the c axis at magnetic fields between 4 and 4.7 T, depending on temperature. The low-field antiferromagnetic phase boundary is shown to join the spin-flop line tangentially at the so-called bicritical point, where there is a suppression of the ordering temperature. At the bicritical field, we observe an increased intensity of the Lorentz broadened elastic scattering at magnetic Bragg peaks above TN as compared to zero field and 10 T, without an increase in peak width. This suggests an increased density of fluctuations at the bicritical field as compared to zero field.

McLarnon Journal Electrochimica Acta Volume 45 Pagination 225-233 Keywords interfacial films, manganese oxide electrode Abstract A thin-film spinel Li2Mn4O9 electrode was prepared by spin coating onto a Pt substrate. Spectroscopic ellipsometry, X-ray diffraction and current-sensing atomic force microscopy (CSAFM) were used to characterize interfacial processes and film formation at this electrode in the presence of 1.0 M LiPF6, EC:DMC (1:1 by volume) electrolyte. Prolonged exposure of the film to the electrolyte at ambient temperature resulted in spontaneous decomposition of the spinel to λ-MnO2 without disruption of the original structure. The surface of the resulting λ-MnO2 film exhibited no significant change in morphology, however a thin passive electrode surface layer was detected by the CSAFM probe. This electrode surface layer exhibited insulating properties and most likely contained Li2O, a by-product of Li2Mn4O9 decomposition.

Composition dependence of average and local structure of xLi(Li1/3Mn2/3)O2(1?x)Li(Mn1/3Ni1/3Co1/3)O2 active cathode material for Li ion batteries  

Science Journals Connector (OSTI)

Abstract This study focused on the composition dependence of the crystal structure and cathode performance of xLi(Li1/3Mn2/3)O2(1?x)Li(Mn1/3Ni1/3Co1/3)O2 (0?x?1) prepared by co-precipitation. From charge-discharge tests, it was found that there was large differences in the battery performance between the composition of x=0.2 and x?0.3. For the samples, the average crystal structures were determined by the Rietveld refinement of neutron diffraction patterns. The results indicated that for x=0.2, Li existed at both 2b and 4g sites, whereas for x?0.3, Li was localized at 2b sites and Mn occupied the 4g sites. In order to examine the local crystal structure, pair distribution function (PDF) and extended X-ray absorption fine structure (EXAFS) analyses were carried out. From the PDF analysis, a significant difference was seen in the short-range peaks associated with the transition metal layer for x=0.2, 0.4 and 0.6. The EXAFS results indicated a large difference in the local structure around Mn for x=0.2 and x?0.3. This is thought to be due to ordering of LiMn6 and LiMn5Ni, which is likely to affect cathode performance.

The complexity of layered-spinel yLi{sub 2}MnO{sub 3} {center_dot} (1-y)Li{sub 1+x}Mn{sub 2-x}O{sub 4} (Li:Mn = 1.2:1; 0 = x = 0.33; y = 0.45) composites synthesized at different temperatures has been investigated by a combination of x-ray diffraction (XRD), x-ray absorption spectroscopy (XAS), and nuclear magnetic resonance (NMR). While the layered component does not change substantially between samples, an evolution of the spinel component from a high to a low lithium excess phase has been traced with temperature by comparing with data for pure Li{sub 1+x}Mn{sub 2-x}O{sub 4}. The changes that occur to the structure of the spinel component and to the average oxidation state of the manganese ions within the composite structure as lithium is electrochemically removed in a battery have been monitored using these techniques, in some cases in situ. Our 6Li NMR results constitute the first direct observation of lithium removal from Li{sub 2}MnO{sub 3} and the formation of LiMnO{sub 2} upon lithium reinsertion.

We report the discovery of a diluted magnetic semiconductor, Li(Zn,Mn)P, in which charge and spin are introduced independently via lithium off-stoichiometry and the isovalent substitution of Mn2+ for Zn2+, respectively. Isostructural to (Ga,Mn)As, Li(Zn,Mn)P was found to be a p-type ferromagnetic semiconductor with excess lithium providing charge doping. First-principles calculations indicate that excess Li is favored to partially occupy the Zn site, leading to hole doping. Ferromagnetism with Curie temperature up to 34 K is achieved while the system still shows semiconducting transport behavior.

Observations of the Li, Be, and B isotopes and Constraints on Cosmic-ray Propagation  

SciTech Connect

The abundance of Li, Be, and B isotopes in galactic cosmic rays (GCR) between E=50-200 MeV/nucleon has been observed by the Cosmic Ray Isotope Spectrometer (CRIS) on NASA's ACE mission since 1997 with high statistical accuracy. Precise observations of Li, Be, B can be used to constrain GCR propagation models. We find that a diffusive reacceleration model with parameters that best match CRIS results (e.g. B/C, Li/C, etc) are also consistent with other GCR observations. A {approx}15-20% overproduction of Li and Be in the model predictions is attributed to uncertainties in the production cross-section data. The latter becomes a significant limitation to the study of rare GCR species that are generated predominantly via spallation.

Study on LiCl waste salt treatment process by layer melt crystallization  

SciTech Connect

Layer melt crystallization operated in a static mode has been applied to separate Group I and II chlorides from surrogate LiCl waste salt. The effects of operating conditions such as crystal growing rate(or flux) and initial impurity concentration on separation (or concentration) of cesium, strontium and barium involved in a LiCl melts were analyzed. In a layer crystallization process, separation was impaired by occlusion of impurities and by residual melt adhering to LiCl crystal after at the end of the process. The crystal growth rate strongly affects the crystal structure, therefore the separation efficiency, while the effect of the initial Cs and Sr concentration in LiCl molten salt was nearly negligible.

Observations on microstructure and crystal structure of sintered lithium metatitanate with excess Li  

Science Journals Connector (OSTI)

Crystal grain growth and crystallization of lithium metatitanate with excess Li (Li2+xTiO3+y), which is expected as an advanced ceramic breeder for a future DEMO fusion reactor, were studied in this paper. By the observation of sintered pellets using scanning electron microscope, it was shown that the Li2.1TiO3+y specimens, which have small grains (12?m) and narrow size distribution, can be obtained by sintering in the temperature range from 1000 to 1100C. The observation also showed the rapid grain growth in the Li2.1TiO3 specimens sintered above 1150C. The changes in the crystal structure and the phase transformation with the increase of sintering temperature were also investigated by means of powder X-ray diffraction. Finally, the relationship between the grain growth and the phase state at high temperature was discussed.

The Puzzling Li-rich Red Giant Associated with NGC 6819  

E-Print Network (OSTI)

A Li-rich red giant star (2M19411367+4003382) recently discovered in the direction of NGC 6819 belongs to the rare subset of Li-rich stars that have not yet evolved to the luminosity bump, an evolutionary stage where models predict Li can be replenished. The currently favored model to explain Li enhancement in first-ascent red giants like 2M19411367+4003382 requires deep mixing into the stellar interior. Testing this model requires a measurement of 12C/13C, which is possible to obtain from APOGEE spectra. However, the Li-rich star also has abnormal asteroseismic properties that call into question its membership in the cluster, even though its radial velocity and location on color-magnitude diagrams are consistent with membership. To address these puzzles, we have measured a wide array of abundances in the Li-rich star and three comparison stars using spectra taken as part of the APOGEE survey to determine the degree of stellar mixing, address the question of membership, and measure the surface gravity. We con...

Optimization of LiFePO4 Nanoparticle Suspensions with Polyethyleneimine for Aqueous Processing  

SciTech Connect

Addition of dispersants to aqueous based lithium-ion battery electrode formulations containing LiFePO{sub 4} is critical to obtaining a stable suspension. The resulting colloidal suspensions enable dramatically improved coating deposition when processing electrodes. This research examines the colloidal chemistry modifications based on polyethyleneimine (PEI) addition and dispersion characterization required to produce high quality electrode formulations and coatings for LiFePO{sub 4} active cathode material. The isoelectric point, a key parameter in characterizing colloidal dispersion stability, of LiFePO{sub 4} and super P C45 were determined to be pH = 4.3 and 3.4, respectively. PEI, a cationic surfactant, was found to be an effective dispersant. It is demonstrated that 1.0 wt % and 0.5 wt % PEI were required to stabilize the LiFePO{sub 4} and super P C45 suspension, respectively. LiFePO{sub 4} cathode suspensions with 1.5 wt % PEI demonstrated the best dispersibility of all components, as evidenced by viscosity and agglomerate size of the suspensions and elemental distribution within dry cathodes. The addition of PEI significantly improved the LiFePO{sub 4} performance.

Disproportionation in Li-O{sub 2} Batteries Based on a Large Surface Area Carbon Cathode  

SciTech Connect

In this paper we report on a kinetics study of the discharge process and its relationship to the charge overpotential in a Li-O{sub 2} cell for large surface area cathode material. The kinetics study reveals evidence for a first-order disproportionation reaction during discharge from an oxygen-rich Li{sub 2}O{sub 2} component with superoxide-like character to a Li{sub 2}O{sub 2} component. The oxygen-rich superoxide-like component has a much smaller potential during charge (3.2-3.5 V) than the Li{sub 2}O{sub 2} component (similar to 4.2 V). The formation of the superoxide-like component is likely due to the porosity of the activated carbon used in the Li-O{sub 2} cell cathode that provides a good environment for growth during discharge. The discharge product containing these two components is characterized by toroids, which are assemblies of nanoparticles. The morphologic growth and decomposition process of the toroids during the reversible discharge/charge process was observed by scanning electron microscopy and is consistent with the presence of the two components in the discharge product. The results of this study provide new insight into how growth conditions control the nature of discharge product, which can be used to achieve improved performance in Li-O{sub 2} cell.

Anisotropic phonon-dislocation scattering in deformed LiF  

Science Journals Connector (OSTI)

By direct imaging of ballistic phonons having equivalent temperatures near 4 K in LiF, we have found that a subset of fast-transverse phonons can propagate without scattering even in heavily deformed samples. The highly anisotropic phonon-scattering cross section is consistent with the concept of fluttering dislocations. The magnitude of the scattering cross section has been obtained for the first time. For small plastic deformation the measured cross section agrees with that calculated theoretically using a measured dislocation density. However, at large deformation the calculated cross section is too small, supporting the speculation that a larger density of dislocation dipoles may provide the dominant scattering. Also consistent with the concept of fluttering dislocations, ? irradiation reduces the phonon scattering created by deformation, presumably by pinning of the dislocations. It is demonstrated that the method of phonon imaging used here provides details of phonon scattering processes which are not available from conventional thermal-transport measurements, especially when the scattering is anisotropic.

Theory of Dielectric Constants of LiF  

Science Journals Connector (OSTI)

The static and high-frequency dielectric constants and the effective charge of LiF are calculated on the basis of a simplified model in which the polarizability of the positive ion is neglected and that of the negative ion is attributed entirely to perturbations in the outermost subshell (2p) of electrons. The present calculation differs from the variational treatment of Yamashita mainly in the inclusion of perturbed wave functions differs from the variational treatment of Yamashita mainly in the inclusion of perturbed wave functions for the 2p electrons which are orthogonal to the core-electron wave functions. Also, different methods are employed in evaluating portions of the energy of the crystal in a field and in deducing the effective charge ratio e*e from the calculated energy. It is found that the use of trial wave functions which preserve the orthogonality within individual ions is of prime importance, and leads to results in generally better agreement with observation than the previously used nonorthogonal functions.

The coreshell model with empirical force fields is employed to reproduce the unit-cell parameters of crystal structure, which are in good agreement with the experimental data. In addition, the formation energies of intrinsic defects (Frenkel and antisite) are determined by energetics calculation. From migration energy calculations, it is found that these flurophosphates have a 3D Li{sup +} ion diffusion network forecasting good Li{sup +} ion conducting performances. Accordingly, we expect that this study provides an atomic scale insight as cathode materials for lithium ion batteries. - Graphical abstract: Lithium transition metal fluorophosphates (Li{sub 2}CoPO{sub 4}F and Li{sub 2}NiPO{sub 4}F).

Thermal and electrochemical characterization of MCMB/LiNi{sub 1/3}Co{sub l/3}Mn{sub l/3}O{sub 2} using LiBoB as an electrolyte additive.  

SciTech Connect

The gas generation associated with the use of the lithium bis(oxalate)borate--(LiBoB) based electrolyte at the elevated temperature were detected in the pouch cell (MCMB/LiNi1/3Co1/3Mn1/3O2 with 10% excess Li), which might prevent the LiBoB usage as a salt. However, the cell capacity retention was improved significantly, from 87 to 96% at elevated temperature, when using LiBoB as an electrolyte additive. The capacity fade during cycling is discussed using dQ/dE, area specific impedance, and frequency response analysis results. Most of the capacity loss in the cell is associated with the rise in the cell impedance. Moreover, results from the differential scanning calorimetry indicate that the thermal stability of the negative electrode with the solid electrolyte interface (SEI) formed by the reduction of the LiBoB additive was greatly improved compared with that obtained from the reduction of LiPF6-based electrolyte without additive. In this case, the onset temperature of the breakdown of the LiBoB-based SEI is 150 C which is higher than that of the conventional electrolyte without additive. Furthermore, the total heat generated between 60 and 170 C is reduced from 213 to 70 J g{sup -1} when using LiBoB as electrolyte additive compared to the one without additive. In addition, the thermal stability of the charged LiNi1/3Co1/3Mn1/3O2 with 10% excess Li was not affected when using LiBoB as an electrolyte additive.

Li{sub 4}FeH{sub 6}: Iron-containing complex hydride with high gravimetric hydrogen density  

SciTech Connect

Li{sub 4}FeH{sub 6}, which has the highest gravimetric hydrogen density of iron-containing complex hydrides reported so far, is synthesized by hydrogenation of a powder mixture of iron and LiH above 6.1 GPa at 900?C. In situ synchrotron radiation X-ray diffraction measurements reveal that while kinetics require high temperature and thus high pressure for the synthesis, Li{sub 4}FeH{sub 6} is expected to be thermodynamically stable slightly below room temperature at ambient pressure; further synthetic studies to suppress the kinetic effects may enable us to synthesize Li{sub 4}FeH{sub 6} at moderate pressures. Li{sub 4}FeH{sub 6} can be recovered at ambient conditions where Li{sub 4}FeH{sub 6} is metastable.

A candidate Li B H 4 for hydrogen storage: Crystal structures and reaction mechanisms of intermediate phases  

Science Journals Connector (OSTI)

First-principles calculation and x-ray diffraction simulation methods have been used to explore crystal structures and reaction mechanisms of the intermediate phases involved in dehydriding of Li B H 4 . Li B H 4 was found to dehydride via two sequential steps: first dehydriding through LiBH followed by the dehydriding of LiBH through LiB. The first step which releases 13.1 wt. % hydrogen was calculated to have an activation barrier of 2.33 eV per formula unit and was endothermic by 1.28 eV per formula unit while the second step was endothermic by 0.23 eV per formula unit. On the other hand if Li B H 4 and LiBH each donated one electron possibly to the catalyst doped on their surfaces it was found that the barrier for the first step was reduced to 1.50 eV . This implies that the development of the catalyst to induce charge migration from the bulk to the surface is essential to make Li B H 4 usable as a hydrogen storagematerial in a moderate temperature range which is also important to stabilize the low-temperature structure of P n m a (no. 62) LiBH on dehydrogenation. Consequently the high 13.1 wt. % hydrogen available from the dehydriding of Li B H 4 and LiBH and their phase stability on P n m a when specific catalysts were used suggest that Li B H 4 has good potential to be developed as the hydrogen storage medium capable of releasing the Department of Energy target of 6.5 wt. % for a hydrogen fuel cell car in a moderate temperature range.

Neutron detection properties of Li6Y(BO3)3:Ce crystal  

Science Journals Connector (OSTI)

Abstract Li6Y(BO3)3:Ce crystal is a promising type of scintillator for neutron detection. In this study, the properties of Li6Y(BO3)3:3at%Ce are studied, including its ? sensitivity, neutron efficiency, ?/? ratio, relative light yield, neutron pulse-height spectrum and decay time. Geant4 simulations indicate that its capture efficiency for thermal neutrons is as high as 78% for the natural abundances of the boron and lithium elements. The ?/? ratio of Li6Y(BO3)3:Ce is measured to be 0.03, which is 10 times lower than that of lithium glass. If the per-MeV light yield of lithium glass is defined to be 100, then the light yields generated by Li6Y(BO3)3:Ce for ? rays and ? particles are 253.3 and 24.8, respectively. Under ?-ray irradiation, the light yield of Li6Y(BO3)3:Ce is approximately 6 times lower than that of NaI:Tl. In neutron detection, the neutron signal can be clearly distinguished from the backgrounds caused by the 252Cf source itself. Li6Y(BO3)3:Ce is also a fast scintillator, with decay times of 48.614.4ns, 24.613.3ns and 37.817.8ns under irradiation with ? rays, ? particles and thermal neutrons, respectively. This study offers a systematic study of useful parameters of Li6Y(BO3)3:3at%Ce crystal for application in and the improvement of neutron detection.

Semiconducting p-type MgNiO:Li epitaxial films fabricated by cosputtering method  

SciTech Connect

Li-doped ternary Mg{sub x}Ni{sub 1-x}O thin films were deposited on (0001) Al{sub 2}O{sub 3} substrates by a radio frequency (RF) magnetron cosputtering method with MgO and NiO:Li targets. The Mg mole fraction and Li content were relatively controlled by changing RF power for the MgO target over a range of 0-300 W, while the NiO:Li target was kept at 150 W. As a result, all films were epitaxially grown on (0001) Al{sub 2}O{sub 3} substrates with the relationship of [110]{sub NiO}||[1110]{sub Al2O3}, [112]{sub NiO}||[2110]{sub Al2O3} (in-plane), and [111]{sub NiO}||[0001]{sub Al2O3} (out-of-plane), and showed p-type semiconducting properties. Furthermore, from x-ray diffraction patterns, the authors found that MgO was effectively mixed with NiO:Li without structural deformation due to low lattice mismatch (0.8%) between NiO and MgO. However, the excess Li contents degraded the crystallinity of the MgNiO films. The band-gap of films was continuously shifted from 3.66 eV (339 nm) to 4.15 eV (299 nm) by the RF power of the MgO target. A visible transmittance of more than 80% was exhibited at RF powers higher than 200 W. Ultimately, the electrical resistivity of p-type MgNiO films was improved from 7.5 to 673.5 {Omega}cm, indicating that the Li-doped MgNiO films are good candidates for transparent p-type semiconductors.

Cluster-continuum quantum mechanical models to guide the choice of anions for Li{sup +}-conducting ionomers  

SciTech Connect

A quantum-mechanical investigation on Li poly(ethylene oxide)-based ionomers was performed in the cluster-continuum solvation model (CCM) that includes specific solvation in the first shell surrounding the cation, all surrounded by a polarizable continuum. A four-state model, including a free Li cation, Li{sup +}-anion pair, triple ion, and quadrupole was used to represent the states of Li{sup +} within the ionomer in the CCM. The relative energy of each state was calculated for Li{sup +} with various anions, with dimethyl ether representing the ether oxygen solvation. The population distribution of Li{sup +} ions among states was estimated by applying Boltzmann statistics to the CCM energies. Entropy difference estimates are needed for populations to better match the true ionomer system. The total entropy change is considered to consist of four contributions: translational, rotational, electrostatic, and solvent immobilization entropies. The population of ion states is reported as a function of Bjerrum length divided by ion-pair separation with/without entropy considered to investigate the transition between states. Predicted concentrations of Li{sup +}-conducting states (free Li{sup +} and positive triple ions) are compared among a series of anions to indicate favorable features for design of an optimal Li{sup +}-conducting ionomer; the perfluorotetraphenylborate anion maximizes the conducting positive triple ion population among the series of anions considered.

We observed gradual structural degradation of the graphite, which was most pronounced on the electrode surface but also extended into the bulk of the electrode. Graphite particles close to the Cu current collector remained almost unchanged, whereas those close to the electrode/electrolyte interface suffered significant structural damage. Structural degradation of the graphite led to an increased anode surface reactivity vs. the electrolyte. A thick layer of inorganic products from side reactions was observed on the disordered carbon areas of the anode.

Sequential breakup cross section of /sup 6/Li by /sup 40/Ca  

SciTech Connect

The differential cross section for the excitation of the unbound 3/sup +/ (2.18 MeV) state in /sup 6/Li was measured by scattering a 227 MeV /sup 40/Ca beam from a /sup 6/Li target. Additionally, the cross section for the 3/sup -/ (3.74 MeV) state in /sup 40/Ca was measured at the same center-of-mass energy by scattering a 34 MeV /sup 6/Li beam from /sup 40/Ca. The cross section for excitation of the 3/sup +/, 2.18 MeV state in /sup 6/Li is 3--5 times larger than that of the /sup 40/Ca 3/sup -/ state. The present data and previously measured elastic scattering data have been analyzed in the framework of both distorted-wave Born approximation and coupled channels calculations, using double folded real potentials, to determine the influence of the inelastic states on the elastic scattering cross section. We find that the elastic scattering is very sensitive to coupled channels effects arising from the 3/sup +/ state in /sup 6/Li.

Pushing the Theoretical Limit of Li-CFx Batteries: A Tale of Bi-functional Electrolyte  

SciTech Connect

In a typical battery, electrodes deliver capacities less or equal the theoretical maxima of the electrode materials.1 The inert electrolyte functions solely as the ionic conductor without contribution to the cell capacity because of its distinct mono-function in the concept of conventional batteries. Here we demonstrate that the most energy-dense Li-CFx battery2 delivers a capacity exceeding the theoretical maximum of CFx with a solid electrolyte of Li3PS4 (LPS) that has dual functions: as the inert electrolyte at the anode and the active component at the cathode. Such a bi-functional electrolyte reconciles both inert and active characteristics through a synergistic discharge mechanism of CFx and LPS. Li3PS4 is known as an inactive solid electrolyte with a broad electrochemical window over 5 V.3 The synergy at the cathode is through LiF, the discharge product of CFx, which activates the electrochemical discharge of LPS at a close electrochemical potential of CFx. Therefore, the solid-state Li-CFx batteries output 126.6% energy beyond their theoretic limits without compromising the stability of the cell voltage. The extra energy comes from the electrochemical discharge of LPS, the inert electrolyte. This bi-functional electrolyte revolutionizes the concept of conventional batteries and opens a new avenue for the design of batteries with an unprecedentedly high energy density.

Surface structural analysis of LiF(100) thin films grown on Pt(111)  

SciTech Connect

The surface structure of a multilayer LiF(100) thin film grown on Pt(111) from the vapor has been determined by the automated tensor low energy electron diffraction (LEED) method. The final structure, which refined to a Pendry R-factor (RP) of 0.24, had a surface corrugation (D1) of 0.24+-0.04 Angstrom due to the Li+ being displaced towards the bulk, leaving the initially coplanar F - unshifted. A similar intralayer corrugation due to the movement of the Li+ was also observed in the layer immediately under the surface layer, although to a lesser degree: D2=0.07+-0.04 Angstrom. This asymmetric relaxation resulted in the reduction of the first interlayer spacing, d(F2-Li1), to 1.77+-0.0 6 Angstrom from the ideal value of 2.01 Angstrom. The second interlayer spacing, d(Li3-F2), was within error bars of the bulk value, 2.01 Angstrom.

Electrochemical and Structural Study of the Layered, 'Li-Excess' Lithium-Ion Battery Electrode Material Li[Li[subscript 1/9]Ni[subscript 1/3]Mn[subscript 5/9  

SciTech Connect

The overcapacity mechanism and high voltage process of the Li-excess electrode material Li[Li{sub 1/9}Ni{sub 1/3}Mn{sub 5/9}]O{sub 2} are studied by solid-state NMR, X-ray diffraction, X-ray absorption spectroscopy, transmission electron microscopy, combined with galvanostatic and potentiostatic intermittent titration electrochemical measurements. The cycling performance is improved noticeably when the material is cycled between potential windows of 5.3-2.5 V compared to 4.6-2.5 V. Diffraction data show that structural changes occur at high voltages, the solid-state NMR data of the same samples indicating that the high voltage processes above 4.4 V are associated with Li removal from the structure, in addition to electrolyte decomposition. The NMR spectra of the discharged samples show that cation rearrangements in the transition metal layers have occurred. The XAS spectra confirm that the Mn oxidation state remains unchanged at 4+, whereas Ni{sup 2+} is oxidized to Ni{sup 4+} on charging to 4.4 V, returning to Ni{sup 2+} on discharge, independent of the final charge voltage. A significant change of the shape of the Ni edge is observed in the 4.6-5.3 V potential range on charge, which is ascribed to a change in the Ni local environment. No O{sub 2} evolution was detected based on ex situ analysis of the gases evolved in the batteries, the TEM data showing that thick passivating films form on the electrodes. The results suggest that at least some of the oxygen loss from these lithium-excess materials occurs via a mechanism involving electrolyte decomposition.

Relation between crystal structures, electronic structures, and electrode performances of LiMn2?xMxO4 (M = Ni, Zn) as a cathode active material for 4V secondary Li batteries  

Science Journals Connector (OSTI)

We investigated the relation between the electrode performance and electronic states of LiMn2?xMxO4 (M=Ni, Zn) as cathode active materials for the 4V class of lithium secondary batteries. The cycle performance is improved by substitution of Mn with Ni or Zn. We obtained the electron density distribution by XRD using the MEM/Rietveld method. Moreover, we investigated the electronic states of LiMn1.75M0.25O4 (M=Mn, Ni, Zn) using first-principles calculation by the DV-X? method. The net charges of each atom, and the bond overlap populations of Li?O, Mn?O, Ni?O and Zn?O were calculated. From the results, Li has a high ionicity and the covalent bonding of the Mn?O of LiMn1.75M0.25O4 (M=Ni, Zn) is stronger than that of LiMn2O4. As a result of the DOS, the oxygen 2p orbital and Mn 3d orbital provides the overlap and the overlap of LiMn1.75M0.25O4 is greater than that of LiMn2O4.

A comparison of the complete fusion cross sections at above-barrier energies with the existing data of $^{11,10}$B+$^{159}$Tb and $^{7}$Li+$^{159}$Tb shows that the extent of suppression is correlated with the $\\alpha$-separation energies of the projectiles. It has been argued that the Dy isotopes produced in the reaction $^{6}$Li+$^{159}$Tb, at below-barrier energies are primarily due to the $d$-transfer to unbound states of $^{159}$Tb, while both transfer and incomplete fusion processes contribute at above-barrier energies.

Effect of the breakup process on the direct reaction with a {sup 6}Li projectile  

SciTech Connect

We investigate the effect of the breakup process on the direct reaction (DR) for {sup 6}Li. In order to study this effect, we introduce the experimental and semiexperimental ratio factors R{sup expt} and R{sup th} by using the semiexperimental and experimental {alpha}-production cross sections and DR cross sections. The average values of the ratio R{sup expt} (R{sup th}) for the {sup 6}Li+{sup 208}Pb and {sup 6}Li+{sup 209}Bi systems are 0.90 (0.91) and 0.86 (0.85), respectively. From these results, it can be seen that the {alpha}-production cross sections are the main contribution to the DR cross sections.

Impact of active material surface area on thermal stability of LiCoO2 cathode  

Science Journals Connector (OSTI)

Abstract Thermal stability of charged LiCoO2 cathodes with various surface areas of active material is investigated in order to quantify the effect of LiCoO2 surface area on thermal stability of cathode. Thermogravimetric analyses and calorimetry have been conducted on charged cathodes with different active material surface areas. Besides reduced thermal stability, high surface area also changes the active material decomposition reaction and induces side reactions with additives. Thermal analyses of LiCoO2 delithiated chemically without any additives or with a single additive have been conducted to elaborate the effect of particle size on side reactions. Stability of cathodeelectrolyte system has been investigated by accelerating rate calorimetry (ARC). Arrhenius activation energy of cathode decomposition has been calculated as function of conversion at different surface area of active material.

Disentangling reaction mechanisms for ? production in the 6Li + 209Bi reaction  

Science Journals Connector (OSTI)

Inclusive breakup ? cross sections (??incl) are measured for the 6Li?+?209Bi reaction at bombarding energies Elab=2450MeV. The ??incl was observed to be a substantial fraction of the total reaction cross section over the entire energy range, and it exhausts almost whole of the reaction cross section at sub-barrier energies. An investigation on the origin of large inclusive ? reveals that most of the ? particles are produced by noncapture breakup (6Li??+d) and incomplete fusion via d capture. The combined cross sections of noncapture breakup, d capture, and transfer reactions successfully explain the origin of most of the experimental ??incl over the measured energy range. A comparison of the ??incl versus reduced energies for several targets involving 6Li as projectile shows that the cross sections are independent of target. Interestingly, the difference between reaction and complete fusion cross sections ?reac??CF for several reactions also shows the same behavior.

Thermochemistry of phosphorus oxynitrides: PON and LiNaPON glasses  

SciTech Connect

High-temperature solution calorimetry has been very useful in elucidating the energetics of many oxide materials. Recently, a sodium molybdate melt, 3Na{sub 2}O{center{underscore}dot}4MoO{sub 3}, has been shown to be very effective for nitride calorimetry. This methodology has now been used to determine the energetics of formation of phosphorus oxynitride PON samples and of a series of LiNaPON oxynitride glasses. The magnitude of the energetics of nitrogen/oxygen substitution within PON and LiNaPON glasses has been correctly evaluated by using N-N, O-O, P-N, and P-O bond strengths. The in-situ precipitation of metallic particles from corresponding oxides in LiNaPON glasses has been predicted from high-temperature solution calorimetry results and appropriate thermodynamic cycles. The results constitute the first set of energetic data on nitridophosphates.

Superionicity in the hydrogen storage material Li2NH: Molecular dynamics simulations  

Science Journals Connector (OSTI)

We have employed ab initio molecular dynamics simulations in an attempt to study a temperature-induced order-disorder structural phase transformation that occurs in Li2NH at about 385 K. A structural phase transition was observed by us in the temperature range 300400 K, in good agreement with experiment. This transition is associated with a melting of the cation sublattice (Li+), giving rise to a superionic phase, which in turn is accompanied by an order-disorder transition of the N-H bond orientation. The results obtained here can contribute to a better understanding of the hydrogen storage reactions involving Li2NH and furthermore broaden its possible technological applications toward batteries and fuel cells.

The mechanism of HF formation in LiPF6 based organic carbonate electrolytes

The mechanism of HF formation in LiPF6 based organic carbonate electrolytes The mechanism of HF formation in LiPF6 based organic carbonate electrolytes Title The mechanism of HF formation in LiPF6 based organic carbonate electrolytes Publication Type Journal Article Year of Publication 2012 Authors Lux, Simon F., Ivan T. Lucas, Elad Pollak, Stefano Passerini, Martin Winter, and Robert Kostecki Journal Electrochemistry Communications Volume 14 Start Page 47 Issue 1 Pagination 47-50 Date Published 01/2012 Keywords Hydrofluoric acid, LiPF6 degradation, Lithium ion batteries, spectroscopic ellipsometry Abstract Spectroscopic ellipsometry was used to study the time-dependent formation of HF upon the thermal degradation of LiPF6 at 50 °C in a lithium ion battery electrolyte containing ethylene carbonate and diethyl carbonate. The generated HF was monitored by following the etching rate of a 300 nm thick SiO2 layer, grown on both sides of a silicon wafer substrate, as a function of the immersion time in the electrolyte at 50 °C. It was found that the formation of HF starts after 70 h of exposure time and occurs following several different phases. The amount of generated HF was calculated using an empirical formula correlating the etching rate to the temperature. Combining the results of the HF formation with literature data, a simplified mechanism for the formation of the HF involving LiPF6 degradation, and a simplified catalytical reaction pathway of the formed HF and silicon dioxide are proposed to describe the kinetics of HF formation.

Vector polarized /sup 6/Li scattering from /sup 12/C and /sup 16/O  

SciTech Connect

The elastic scattering vector analyzing powers for /sup 6/Li+/sup 16/O at 25.7 MeV and /sup 6/Li+/sup 12/C at 30 MeV have been measured. In addition, measurement of the vector analyzing power for inelastic /sup 6/Li scattering has been made for the 2/sup +/ (4.44 MeV) state in /sup 12/C. Excitation function data for /sup 6/Li+/sup 16/O elastic and inelastic scattering have also been measured at five angles for /sup 6/Li lab energies through the range 15--28 MeV in 375 keV steps. These data show the system to be resonance free at 25.7 MeV. The data have been analyzed in the coupled channels framework, employing the double folding model for the real part of the nuclear scattering potential. The coupling strengths in the coupled channels calculations were determined from inelastic scattering cross-section data directly. The elastic scattering vector analyzing powers arise from a complicated interference between channel coupling and spin-orbit contributions, whereas the /sup 12/C, 2/sup +/ inelastic vector analyzing power arises from the spin-orbit potential only. Inelastic scattering analyzing powers may allow the shape and strength of heavy-ion spin-orbit potentials to be investigated more clearly than do the elastic scattering analyzing powers. The normalization of the double-folded real potential was found to be in the range 0.85--1.00 in the coupled channel calculations, thus bringing the normalization of /sup 6/Li scattering into agreement with other projectiles.

Relativistic calculations of the isotope shifts in highly charged Li-like ions  

E-Print Network (OSTI)

Relativistic calculations of the isotope shifts of energy levels in highly charged Li-like ions are performed. The nuclear recoil (mass shift) contributions are calculated by merging the perturbative and large-scale configuration-interaction Dirac-Fock-Sturm (CI-DFS) methods. The nuclear size (field shift) contributions are evaluated by the CI-DFS method including the electron-correlation, Breit, and QED corrections. The nuclear deformation and nuclear polarization corrections to the isotope shifts in Li-like neodymium, thorium, and uranium are also considered. The results of the calculations are compared with the theoretical values obtained with other methods.

Report for in-situ 7Li NMR experiment in PNNL Phase -1  

SciTech Connect

To understand the detailed local structural evolution, an in-situ 7Li NMR study was performed. An operando identification of the lithium germanide phases under various cycling regimens permitted understanding of the kinetics of phase transition between different structural phases, including the amorphous phases, and how these correlated with capacity retention. Combining data from TEM and in-situ 7Li NMR, we discovered that the phase inter-conversion during cycling was mediated by co-existing amorphous and crystalline phases, and that the high capacity observed was correlated with an over-lithiated lithium germanide phase.

First Principles Prediction of Nitrogen-doped Carbon Nanotubes as a High-Performance Cathode for Li-S Batteries  

SciTech Connect

The insulating nature of sulfur and the solubility of the polysulfide in organic electrolyte are two main factors that limit the application of lithium sulfur (Li-S) battery systems. Enhancement of Li conductivity, identification of a strong adsorption agent of polysulfides and the improvement of the whole sulfur-based electrode are of great technological importance. The diffusion of Li atoms on the outer-wall, inner-wall and inter-wall spaces in nitrogen-doped double-walled carbon nanotubes (CNTs) and penetrations of Li and S atoms through the walls are studied using density functional theory. We find that N-doping does not alternate the diffusion behaviors of Li atoms throughout the CNTs, but the energy barrier for Li atoms to penetrate the wall is greatly decreased by N-doping (from ~9.0 eV to ~ 1.0 eV). On the other hand, the energy barrier for S atoms to penetrate the wall remains very high, which is caused by the formation of the chemical bonds between the S and nearby N atoms. The results indicate that Li atoms are able to diffuse freely, whereas S atoms can be encapsulated inside the N-doped CNTs, suggesting that the N-doped CNTs can be potentially used in high performance Li-S batteries.

A synthesis of LiFePO 4 starting from FePO 4 under reducing atmosphere  

Science Journals Connector (OSTI)

A fast and easy way to produce LiFePO 4 starting from FePO 4 used as iron and phosphorus source is proposed. 5% hydrogen is employed as a reducing agent and various compounds containing lithium as lithiation agents. The selected lithiation agents included: LiCl CH 3 COOLi LiOH Li 2 S LiH and Li 2 CO 3 . Solid state synthesis is used for the LiFePO 4 preparation and the so obtained materials are structurally characterized by XRD. The materials are used to fabricate composite electrode and their specific capacity is evaluated by low rate galvanostatic charge/discharge cycles (C/10 rate). Among the various lithium salts the acetate give rise to the LiFePO 4 with the best electrochemical performance. The morphology of this material is further investigated by SEM microscopy and the specific capacity is evaluated as a function of the discharge rate and the cycle number.

Adiabatic Channel Capture Theory Applied to Cold Atom-Molecule Reactions: Li + CaH -> LiH + Ca at 1 K  

E-Print Network (OSTI)

We use quantum and classical adiabatic capture theories to study the chemical reaction Li + CaH -> LiH + Ca. Using a recently developed ab initio potential energy surface, which provides an accurate representation of long-range interactions in the entrance reaction channel, we calculate the adiabatic channel potentials by diagonalizing the atom-molecule Hamiltonian as a function of the atom-molecule separation. The resulting adiabatic channel potentials are used to calculate both the classical and quantum capture probabilities as a function of collision energy, as well as the temperature dependencies of the partial and total reaction rates. The calculated reaction rate agrees well with the measured value at 1 K [V. Singh et al., Phys. Rev. Lett. 108, 203201 (2012)], suggesting that the title reaction proceeds without an activation barrier. The calculated classical adiabatic capture rate agrees well with the quantum result in the multiple partial wave regime of relevance to the experiment. Significant differen...

CsCl Separation From a LiCl-CsCl Mixture by Using a Crystallization Approach  

SciTech Connect

Separation of CsCl and SrCl{sub 2} from LiCl was carried out by using a noble separation technology, the Czochralski crystallization method. It was experimentally confirmed that Cs as well as Sr could be simultaneously separated from a LiCl molten salt by the suggested crystallization process without any kind of additive or adsorption media. The concentrations of Cs and Sr in the LiCl were decreased from 1.53 wt% and 4.18 wt% in the initial salt to a minimum of 114 ppm and 135 ppm in the grown LiCl crystal respectively. The separation mechanism of Cs and Sr is described by the solubility difference of the solutes between the molten and the solid states. It is expected that the total amount of salt waste could be drastically decreased, because most of the LiCl could be recovered for recycling to the electroreduction process. (authors)

Three-phase model for the reversible lithiation/delithiation of SnO anodes in Li-ion batteries  

E-Print Network (OSTI)

Using first-principles calculations, we propose a microscopic model to explain the reversible lithiation/delithiation of tin-oxide anodes in lithium-ion batteries. When the irreversible regime ends, the anode grains consist of layers of Li-oxide separated by Sn bilayers. During the following reversible lithiation, the Li-oxide undergoes two phase transformations that give rise to a Li-enrichment of the oxide and the formation of a SnLi composite. The anode grain structure stays layered and ordered with an effective theoretical reversible capacity of 4.5 Li per Sn atom. The predicted anode volume expansion and voltage profile agree well with experiments, contrary to existing models.

Biased interface between solid ion conductor LiBH{sub 4} and lithium metal: A first principles molecular dynamics study  

SciTech Connect

We use first-principles molecular dynamics to study the electrochemical solid-solid interface between lithium metal and lithium electrolyte LiBH{sub 4}. An external bias is applied by using an effective screening medium. We observe large polarization in the LiBH{sub 4}, because the lithium cations in LiBH{sub 4} are shifted more on one side of the double-well potential of Li{sup +}. This results in a large potential drop in the interface region and a large double-layer capacity corresponding to ca. 70 ?F/cm{sup 2}. H-coordination to the Li atoms plays an important role in the charge-transfer reaction and ion transfer.

Effect of fuel rate and annealing process of LiFePO{sub 4} cathode material for Li-ion batteries synthesized by flame spray pyrolysis method  

SciTech Connect

In this study the effect of fuel rate and annealing on particle formation of LiFePO{sub 4} as battery cathode using flame spray pyrolysis method was investigated numerically and experimentally. Numerical study was done using ANSYS FLUENT program. In experimentally, LiFePO{sub 4} was synthesized from inorganic aqueous solution followed by annealing. LPG was used as fuel and air was used as oxidizer and carrier gas. Annealing process attempted in inert atmosphere at 700C for 240 min. Numerical result showed that the increase of fuel rate caused the increase of flame temperature. Microscopic observation using Scanning Electron Microscopy (SEM) revealed that all particles have sphere and polydisperse. Increasing fuel rate caused decreasing particle size and increasing particles crystallinity. This phenomenon attributed to the flame temperature. However, all produced particles still have more amorphous phase. Therefore, annealing needed to increase particles crystallinity. Fourier Transform Infrared (FTIR) analysis showed that all particles have PO4 function group. Increasing fuel rate led to the increase of infrared spectrum absorption corresponding to the increase of particles crystallinity. This result indicated that phosphate group vibrated easily in crystalline phase. From Electrochemical Impedance Spectroscopy (EIS) analysis, annealing can cause the increase of Li{sup +} diffusivity. The diffusivity coefficient of without and with annealing particles were 6.8439910{sup ?10} and 8.5988810{sup ?10} cm{sup 2} s{sup ?1}, respectively.

Synthesis, structural characterization and Li{sup +} ion conductivity of a new vanado-molybdate phase, LiMg{sub 3}VMo{sub 2}O{sub 12}  

SciTech Connect

A new vanado-molybdate LiMg{sub 3}VMo{sub 2}O{sub 12} has been synthesized, the crystal structure determined an ionic conductivity measured. The solid solution Li{sub 2-z}Mg{sub 2+z}V{sub z}Mo{sub 3-z}O{sub 12} was investigated and the structures of the z=0.5 and 1.0 compositions were refined by Rietveld analysis of powder X-ray (XRD) and powder neutron diffraction (ND) data. The structures were refined in the orthorhombic space group Pnma with a{approx}5.10, b{approx}10.4 and c{approx}17.6 A, and are isostructural with the previously reported double molybdates Li{sub 2}M{sub 2}(MoO{sub 4}){sub 3} (M=M{sup 2+}, z=0). The structures comprise of two unique (Li/Mg)O{sub 6} octahedra, (Li/Mg)O{sub 6} trigonal prisms and two unique (Mo/V)O{sub 4} tetrahedra. A well-defined 1:3 ratio of Li{sup +}:Mg{sup 2+} is observed in octahedral chains for LiMg{sub 3}VMo{sub 2}O{sub 12}. Li{sup +} preferentially occupies trigonal prisms and Mg{sup 2+} favours octahedral sheets. Excess V{sup 5+} adjacent to the octahedral sheets may indicate short-range order. Ionic conductivity measured by impedance spectroscopy (IS) and differential scanning calorimetry (DSC) measurements show the presence of a phase transition, at 500-600 {sup o}C, depending on x. A decrease in activation energy for Li{sup +} ion conductivity occurs at the phase transition and the high temperature structure is a good Li{sup +} ion conductor, with {sigma}=1x10{sup -3}-4x10{sup -2} S cm{sup -1} and E{sub a}=0.6 to 0.8 eV. - Graphical abstract: A new vanado-molybdate LiMg{sub 3}VMo{sub 2}O{sub 12} has been synthesized and the crystal structure determined.
