Abstract

Plasma electrolytic oxidation (PEO) processing of EV31 magnesium alloy has been carried out in fluoride containing electrolyte under bipolar pulse current regime. Unusual PEO cathodic micro-discharges have been observed and investigated. It is shown that the cathodic micro-discharges exhibit a collective intermittent behavior, which is discussed in terms of charge accumulations at the layer/electrolyte and layer/metal interfaces. Optical emission spectroscopy is used to determine the electron density (typ. 10{sup 15} cm{sup −3}) and the electron temperature (typ. 7500 K) while the role of F{sup −} anions on the appearance of cathodic micro-discharges is pointed out.

Micro-hollow cathode discharge arrays: high pressure, nonthermal plasma sources

Technical Report Schoenbach, Karl

Microhollow cathode discharges are gas discharges between a hollow cathode and a planar or hollow anode with electrode dimensions in the 100 mm range. The characteristics of the microhollow cathode discharges allow their utilization in flat panel excimer (UV and VUV) lamps, as micro for gaseous emission treatment, and as broad area electron and ion sources. The electrical and optical properties of these nonthermal, high-pressure discharges have been studied, with particular emphasis on their use as compact, direct current excimer lamps, and, to a lesser degree, as gas reactors for treatment of polluted gases. The large concentration of high-energy electrons,more »« less
Electrolyte Reactivity on the MgV₂O₄ Cathode Surface

Journal Article Jeong, Heonjae; Nguyen, Dan-Thien; Yang, Yingjie; ... - ACS Applied Materials and Interfaces

Predictive understanding of the solvation-dependent reactivity and molecular interaction of electrolyte ions and solvent molecules on reactive electrodes has been a major challenge but is essential for addressing instabilities and surface passivation that occur at electrode-electrolyte interface (EEI) of multivalent Mg batteries. In this work, the isolated intrinsic reactivities of prominent chemical species present in magnesium bis(trifluoromethanesulfonimide) (Mg(TFSI)₂) in diglyme (G2) electrolytes, including ionic (TFSI^-, [Mg(TFSI)]⁺, [Mg(TFSI):G2]⁺, [Mg(TFSI):2G2]⁺) as well as neutral molecules (G2) on magnesium vanadate cathode (MgV₂O₄) surface has been studied using a combination of first-principles calculations and multimodal analysis of well-defined cathode electrolyte interphase (CEI) layers.

Polymeric electrolytes for ambient temperature lithium batteries: Final report

Technical Report Farrington, G.

During this reporting period a number of novel solid polymer electrolytes formed by salts of multivalent cations and poly(ethylene oxide) (PEO) have been prepared and characterized. These materials are of interest not only because of their potential ionic conductivities, but also because some of them may have electronic conductivity and oxidizing power which would be useful for novel electrode materials in all-solid-state batteries. Two broad classes of materials were investigated: PEO solutions of Zn(II), Cd(II), and Pb(II), all of which are potential electrolytes for solid-state batteries, and PEO solutions of transition metal salts, which are of interest as possible cathodemore »« less

Cell performance of ultra-thin polymer-cathode cell systems. Part 2. Cation intercalating composite polymer cathode. Technical report, 1 January 1989-1 March 1990

Technical Report Naoi, K; Smyrl, W; Owens, B

Theoretical specific energy and power densities for thin film Li/LE or SPE/CP cell systems were calculated by modeling a bipolar-design polymer cathode rechargeable cell with hardware where LE, SPE and CP represent the liquid electrolyte (2M LiClO4(PC)), solid polymer electrolyte (PEO(8)LiX) and the conductive polymer(polypyrrole). The cell performance is obtained for a cation-intercalating PPy-PVS composite film which is composed of polypyrrole(PPy) into which has been incorporated the polymer anion, polyvinylsolfonate(PVS) during deposition. The energy and power densities are estimated as a function of cathode thickness (1 to 100,000 micron), active cell area (1 to 10,000 sq cm) and the numbermore »« less
Solid state cathode materials for secondary magnesium-ion batteries that are compatible with magnesium metal anodes in water-free electrolyte

Journal Article Crowe, Adam - Journal of Solid State Chemistry

With high elemental abundance, large volumetric capacity, and dendrite-free metal deposition, magnesium metal anodes offer promise in beyond-lithium-ion batteries. However, the increased charge density associated with the divalent magnesium-ion (Mg{sup 2+}), relative to lithium-ion (Li{sup +}) hinders the ion-insertion and extraction processes within many materials and structures known for lithium-ion cathodes. As a result, many recent investigations incorporate known amounts of water within the electrolyte to provide temporary solvation of the Mg{sup 2+}, improving diffusion kinetics. Unfortunately with the addition of water, compatibility with magnesium metal anodes disappears due to forming an ion-insulating passivating layer. In this short review, recentmore »« less
