Title: On fabrication procedures of Li-ion conducting garnets

Abstract

Ceramic oxides exhibiting high lithium-ion mobility at room temperature receive broad attention as candidate electrolytes for lithium batteries. Lithium-stuffed garnets from the Li{sub 7}La{sub 3}Zr{sub 2}O{sub 12} group seem to be especially promising because of their high ionic conductivity at room temperature and their electrochemical stability. In this work, we discuss factors that affect formation of the garnet in its bulk form or in the form of thick and thin films. We demonstrate that zinc oxide can be applied as a sintering aid that facilitate the formation of the highly conducting cubic Li{sub 7}La{sub 3}Zr{sub 2}O{sub 12} garnet phase in a single-step sintering procedure. Based on our experience with the single-step sintering experiments, we successfully fabricated a thick-film membrane consisting of a garnet solid electrolyte using the tape casting technique. In order to reduce the thickness of the electrolyte even further we investigated the fabrication of a thin-film Li{sub 7}La{sub 3}Zr{sub 2}O{sub 12} electrolyte by means of the pulsed laser deposition technique.

  • In order to investigate the influence of covalent bonding within the garnet framework on the conductivity of Li+ in the interstitial space, the Li+ conductivities in the family of Sn-based compounds Li6La3 SnMO12 (M = Sb, Nb, Ta) have been obtained and are compared with those of Li6La3ZrMO12. Refinement of the neutron diffraction pattern of Li6La3 SnNbO12shows that the interstitial tetrahedral sites (24d ) are about half-occupied and most of the Li in the interstitial bridging octahedral sites are displaced from the center position (48g ). The Sb-based compound has the largest lattice parameter while the Ta-based compound has themore » highest Li+-ion conductivity of 0.42 10 4 Scm 1.« less
  • The authors studied the Li/sub 4/GeO/sub 4/-Li/sub 2/SeO/sub 4/ system as a continuation of an earlier investigation of solid electrolytes on the basis of lithium orthogermanate. The solid electrolytes were synthesized by sintering samples which had been pressed from a mixture of highly disperse powders of Li/sub 2/SeO/sub 4/ and Li/sub 4/GeO/sub 4/. The x-ray phase analysis was performed with a DRON-2 diffractometer in Cu Kalpha-radiation with a nickel filter. Electric resistance was measured with an R502 ac bridge using silver electrodes that had been applied thermochemically with a paste based on silver carbonate. The lowest values of specific resistancemore » are seen near the lower limit of the single-phase region of P-solid solutions. This is in accord with the decisive influence of the concentration of highly mobile carriers (the interstitial lithium ions) on the transport properties of structures similar to gamma-Li/sub 3/PO/sub 4/. The number of interstitial lithium ions increases with decreasing x, and will be highest at the lower limit of the region of existence of P-solid solutions.« less
  • A novel Li-rich cathode Li[Li1/6Fe1/6Ni1/6Mn1/2]O-2 (0.4Li(2)MnO(3-)0.6LiFe(1/3)Ni(1/3)Mn(1/3)O(2)) was synthesized by a solgel method, which uses citric acid (SC), tartaric acid (ST), or adipic acid (SA) as a chelating agent. The structural, morphological, and electrochemical properties of the prepared samples were characterized by various methods. X-ray diffraction showed that single-phase materials are formed mainly with typical alpha-NaFeO2 layered structure (R3 m), and the SC sample has the lowest Li/Ni cation disorder. The morphological study indicated homogeneous primary particles in good distribution size (100 nm) with small aggregates. The Fe, Ni, and Mn valences were determined by X-ray absorption near-edge structure analysis. Inmore » coin cell tests, the initial reversible discharge capacity of an SA electrode was 289.7 mAh g(-1) at the 0.1C rate in the 1.54.8 V voltage range, while an SC electrode showed a better cycling stability with relatively high capacity retention. At the 2C rate, the SC electrode can deliver a discharge capacity of 150 mAh g(-1) after 50 cycles. Differential capacity vs voltage curves were employed to further investigate the electrochemical reactions and the structural change process during cycling. This low-cost, Fe-based compound prepared by the solgel method has the potential to be used as the high capacity cathode material for Liion batteries.« less
  • The garnets Li{sub 3}Nd{sub 3}W{sub 2}O{sub 12} and Li{sub 5}La{sub 3}Sb{sub 2}O{sub 12} have been prepared by heating the component oxides and hydroxides in air at temperatures up to 950deg. C. Neutron powder diffraction has been used to examine the lithium distribution in these phases. Both compounds crystallise in the space group Ia3-bard with lattice parameters a=12.46869(9)A (Li{sub 3}Nd{sub 3}W{sub 2}O{sub 12}) and a=12.8518(3)A (Li{sub 5}La{sub 3}Sb{sub 2}O{sub 12}). Li{sub 3}Nd{sub 3}W{sub 2}O{sub 12} contains lithium on a filled, tetrahedrally coordinated 24d site that is occupied in the conventional garnet structure. Li{sub 5}La{sub 3}Sb{sub 2}O{sub 12} contains partial occupation ofmore » lithium over two crystallographic sites. The conventional tetrahedrally coordinated 24d site is 79.3(8)% occupied. The remaining lithium is found in oxide octahedra which are linked via a shared face to the tetrahedron. This lithium shows positional disorder and is split over two positions within the octahedron and occupies 43.6(4)% of the octahedra. Comparison of these compounds with related d{sup 0} and d{sup 10} phases shows that replacement of a d{sup 0} cation with d{sup 10} cation of the same charge leads to an increase in the lattice parameter due to polarisation effects.« less
