Electrolyte compositions for high voltage lithium-ion batteries

Patent ·
OSTI ID:1493337
;
The present invention provides an electrolyte composition for a lithium-ion battery comprising LiPF6 in a liquid carrier comprising a carbonate ester and an unsaturated organoboron compound comprising two or three unsaturated hydrocarbon groups, each unsaturated hydrocarbon group being covalently bonded to a boron atom. The unsaturated hydrocarbon groups are independently selected from vinyl, allyl, propargyl, substituted vinyl, substituted allyl, and substituted propargyl. The substituents of the substituted vinyl, allyl and propargyl groups independently comprise one or more of alkyl and phenyl. The alkyl and phenyl groups optionally can bear one or more substituent selected from halogen (e.g., F), hydroxy, amino, alkoxy, and perfluoroalkoxy.
