Abstract

A process for fabricating an electrolyte-electrode composite suitable for high energy alkali metal battery that includes mixing composite electrode materials with excess liquid, such as ethylene carbonate or propylene carbonate, to produce an initial formulation, and forming a shaped electrode therefrom. The excess liquid is then removed from the electrode to compact the electrode composite which can be further compacted by compression. The resulting electrode exhibits at least a 75% lower resistance.

Fabrication methods for low impedance lithium polymer electrodes

Patent Chern, T; MacFadden, K; Johnson, S

A process is described for fabricating an electrolyte-electrode composite suitable for high energy alkali metal battery that includes mixing composite electrode materials with excess liquid, such as ethylene carbonate or propylene carbonate, to produce an initial formulation, and forming a shaped electrode therefrom. The excess liquid is then removed from the electrode to compact the electrode composite which can be further compacted by compression. The resulting electrode exhibits at least a 75% lower resistance.
Composite polymer electrolytes with improved lithium metal electrode interfacial properties. 1: Electrochemical properties of dry PEO-LiX systems

Journal Article Appetecchi, G; Croce, F; Dautzenberg, G - Journal of the Electrochemical Society

Several types of lithium ion conducting polymer electrolytes have been synthesized by hot-pressing homogeneous mixtures of the components, namely, poly(ethylene oxide) (PEO) as the polymer matrix, lithium trifluoromethane sulfonate (LiCF{sub 3}SO{sub 3}), and lithium tetrafluoroborate (LiBF{sub 4}), respectively, as the lithium salt, and lithium gamma-aluminate {gamma}-LiAlO{sub 2}, as a ceramic filler. This preparation procedure avoids any step including liquids so that plasticizer-free, composite polymer electrolytes can be obtained. These electrolyte have enhanced electrochemical properties, such as an ionic conductivity of the order of 10{sup {minus}4} S/cm at 80--90 C and an anodic breakdown voltage higher than 4 V vs. Li.more »« less

Process to produce lithium-polymer batteries

Patent MacFadden, K

A polymer bonded sheet product is described suitable for use as an electrode in a non-aqueous battery system. A porous electrode sheet is impregnated with a solid polymer electrolyte, so as to diffuse into the pores of the electrode. The composite is allowed to cool, and the electrolyte is entrapped in the porous electrode. The sheet products composed have the solid polymer electrolyte composition diffused into the active electrode material by melt-application of the solid polymer electrolyte composition into the porous electrode material sheet. The solid polymer electrolyte is maintained at a temperature that allows for rapid diffusion into themore »« less

Study by electrode impedance spectroscopy of the passivating layer formed on the lithium electrode in aprotic media

Conference Garreau, M; Milandou, B; Thevenin, J - Proc. - Electrochem. Soc.; (United States)

The passivating layers formed on the lithium electrodes in the dioxolane and propylene carbonate based-electrolytes were found to be essentially constituted by polymeric membranes. The concepts of the Nernst diffusion-layer have been used to study the diffusion of the lithium ion in these ''Polymer Electrolyte Interphases'' (PEI). The diffusion model obtained has permitted to determine - through the analysis of the electrode impedance spectroscopy data - the thickness d of the PEI and the diffusion coefficient D of the lithium ion in the pores of this medium. Typically, at equilibrium potential and just after an anodic cleaning of the lithiummore »« less
