Document Type and Number:
WIPO Patent Application WO/2011/034065
Kind Code:
A1
Abstract:
Disclosed is a nonaqueous electrolyte solution which contains an unsaturated sultone compound that has a substituent containing a silicon atom. The unsaturated sultone compound is preferably a compound represented by general formula (1). In general formula (1), R1-R4 each represents an -SiR5R6R7 group, a hydrogen atom, a halogen atom, an alkyl group having 1-10 carbon atoms or the like, and at least one of R1-R4 represents an -SiR5R6R7 group; R5-R7 each represents an alkyl group having 1-10 carbon atoms, an alkoxy group having 1-6 carbon atoms or a phenyl group; and m represents 1, 2 or 3.
