Document Type and Number:

WIPO Patent Application WO/2012/039500

Kind Code:

A1

Abstract:

The present invention relates to a method for manufacturing an electrolyte, an electrolyte solution, a gel electrolyte, an electrolyte membrane and a gel electrolyte battery, and to a lithium-ion secondary battery, and its purpose is to provide an electrolyte that inhibits capacity deterioration from repeated charging and discharging, i.e., that has superior cycle life properties. Further, in a more limited sense, the purpose is to provide an electrolyte having ion conductivity equivalent to that of a conventional electrolyte that uses lithium salt, and having an excellent lithium ionic transference number. The present invention relates to an electrolyte characterised by comprising a blend of (A) an organic acid lithium salt and (B) a boron compound.
