Abstract
A non-aqueous electrolytic solution is provided comprising a non-aqueous solvent, an electrolyte salt, and a siloxane-modified polyoxyalkylene compound having (poly)organosiloxane structures at both ends of polyoxyalkylene. A secondary battery using the same has improved temperature characteristics and high-output characteristics.
Claims4
A non-aqueous electrolytic solution comprising a non-aqueous solvent, an electrolyte salt, and a siloxane-modified polyoxyalkylene compound having the formula (1):
- A-R1O—(CaH2aO)b—R1-A (1)
- wherein R1 is each independently an alkylene group of 2 to 6 carbon atoms, a is an integer of 2 to 4, b is an integer of 1 to 6, and A is a group of the formula (2):
- wherein R2 is each independently an alkyl, cycloalkyl, aryl or aralkyl group of 1 to 10 carbon atoms, which may be substituted with halogen, c is an integer of 0 to 6, and d is 1 or 2.
