CYCLIC CARBONATE-MODIFIED SILOXANE AND METHOD FOR PRODUCING THE SAME, NON-AQUEOUS ELECTROLYTE SOLUTION, SECONDARY CELL AND CAPACITOR

摘要

PPROBLEM TO BE SOLVED: To provide a battery that can give improved discharge characteristics under lower temperature, improved discharge characteristics under high power output and improved safety, particularly, a non-aqueous electrolyte solution that can enable the lithium ion secondary battery or an electrochemical capacitor such as electric double layer capacitor or the like and the cyclic carbonate-modified siloxane that can be effectively used there and provide a method for producing the same. PSOLUTION: The cyclic carbonate-modified siloxane is represented by formula (1) RSP1/SPSBa/SBASBb/SBSiOSB(4-a-b)/2/SB(1) [wherein RSP1/SPis same or different monovalent group selected from a 1 to 30C alkyl which may be substituted with hydroxy or halogen atom, aryl, aralkyl, amino-substituted alkyl, carboxy-substituted alkyl, alkoxy and aryloxy; A is a cyclic carbonate group and represented by formula (2) (wherein a and b are each an integer satisfying 1.0a2.5 and 0.001b1.5 and a+b satisfying 1.001a+b3)].
