Abstract
The present invention provides a non-aqueous electrolytic solution comprising a phosphinoamine-based compound represented by formula (1) below and a lithium ion secondary battery comprising the non-aqueous electrolytic solution. By adding the phosphinoamine-based compound to the non-aqueous electrolytic solution, oxidative degradation in the non-aqueous electrolytic solution is suppressed, and thus gas generation is suppressed.
