NONAQUEOUS ELECTROLYTE SOLUTION FOR SECONDARY BATTERIES, AND SECONDARY BATTERY

摘要

The purpose of the present invention is to provide: a nonaqueous electrolyte solution for secondary batteries, which is capable of achieving excellent low-temperature characteristics, while assuring other characteristics such as electrical conductivity; and a secondary battery which uses the nonaqueous electrolyte solution for secondary batteries. Specifically provided is a nonaqueous electrolyte solution for secondary batteries, which contains: a lithium salt; a specific fluorine-containing ether solvent; a glyme solvent such as monoglyme that contains two ether oxygen atoms; and another glyme solvent such as diglyme that contains 3-5 ether oxygen atoms. Also specifically provided is a secondary battery which uses the nonaqueous electrolyte solution for secondary batteries.
