摘要: Disclosed herein are electrolyte compositions comprising at least one electrolyte component comprising a cyclic carbonate, such as a fluoroethylene carbonate, and at least one additive comprising a 6-member ring heterocyclic sulfate, such as a 1,3 propylene sulfate. The disclosed electrolyte compositions can comprise additional electrolyte components, such as fluorinated acyclic carboxylic acid esters, and additional additives, such as lithium boron compounds, and cyclic carboxylic acid anhydrides, such as maleic anhydride. The improved battery performances, which include high temperature cycling conditions and/or room temperature stability, make these electrolyte compositions useful in electrochemical cells, such as lithium ion batteries.

摘要: The present invention relates to a process for the preparation of halogenated carboxylic anhydrides, e.g. for the preparation of trifluoroacetic anhydride. The preparation is achieved by reacting a halogenated carboxylic acid, e.g. trifluoroacetic acid, with sulfuric acid, oleum and/or disulfuric acid.

摘要: A method for manufacturing a composite electrode for a metal-air electrochemical cell with a liquid electrolyte of basic pH. A liquid solution comprising a fluoropolymer suspended in a solvent is synthesized, then deposited on the outer surface of a porous structure forming an air electrode. The fluoropolymer comprises SO2N groups suitable for conducting hydroxyl ions and is capable of forming a membrane impermeable to at least the liquid electrolyte of basic pH. When the liquid solution is applied to the porous structure, the solvent flows through the porous structure and the fluoropolymer is deposited by aggregating into a layer on the outer surface of the porous structure.
