摘要：
Disclosed are a nonaqueous electrolytic solution for lithium secondary battery comprising an electrolyte dissolved in a nonaqueous solvent and containing at least one compound represented by the formula (I) in an amount of from 0.01 to 10% by mass of the nonaqueous electrolytic solution; a lithium battery containing the electrolytic solution and excellent in low-temperature and high-temperature cycle property; and a formyloxy group-containing compound having a specific structure which is used in lithium batteries, etc. (wherein X represents an alkylene group, an alkenylene group or an alkynylene group; R1 represents H, an alkyl group, a cycloalkyl group or a group of the formula (II); R2 represents an alkyl group, a cycloalkyl group or a group of the formula (II); R3 to R7 each represent H, F, a methoxy group or an ethoxy group.)
