Title:
NON-AQUEOUS SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2013/042503
Kind Code:
A1
Abstract:
The objective of the present embodiment is to provide a non-aqueous secondary battery that effectively suppresses decomposition of an electrolyte fluid even during high-voltage and high-temperature conditions, and that has superior long-term cycling characteristics. The non-aqueous secondary battery, which is provided with an electrolyte fluid containing a non-aqueous electrolyte medium and a supporting electrolyte, is characterized by: the non-aqueous electrolyte medium containing a sulfone compound represented by a predetermined formula and a fluorine-containing ester compound represented by a predetermined formula; the amount of the sulfone compound contained being 20-70 vol% inclusive of the non-aqueous electrolyte medium; and the amount of the fluorine-containing ester compound contained being 20-60 vol% inclusive of the non-aqueous electrolyte medium.
