Title:
NONAQUEOUS ELECTROLYTE, AND LITHIUM ION SECONDARY BATTERY USING THE NONAQUEOUS ELECTROLYTE
Document Type and Number:
Japanese Patent JP2015060819
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a non-aqueous electrolyte which suppresses gas generation, specifically electrolyte decomposition even when applied to a lithium ion secondary battery having a positive electrode potential higher than the prior art and has excellent cycle characteristics, and a lithium ion secondary battery using the non-aqueous electrolyte.SOLUTION: A non-aqueous electrolyte contains a predetermined triple bond-containing phosphoric ester compound (A), a lithium salt compound having no oxalic acid structure (B), a lithium salt compound having an oxalic acid structure (C), and a non-aqueous solvent.
