Title:
NONAQUEOUS ELECTROLYTE AND NONAQUEOUS SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2016/159108
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a nonaqueous electrolyte that contains acetonitrile having an excellent balance between viscosity and the dielectric constant and a fluorine-containing inorganic lithium salt, wherein the generation of complex cations comprising a transition metal and acetonitrile is suppressed, excellent load characteristics are exhibited, and self-discharge during high-temperature storage is suppressed; a further purpose of the present invention is to provide a nonaqueous secondary battery. The present invention relates to a nonaqueous electrolyte which contains: a nonaqueous solvent comprising 30-100 vol% of acetonitrile; a fluorine-containing inorganic lithium salt; and a specific nitrogenous cyclic compound typified by pyridine.
