Electrolytic solution for non-aqueous secondary battery, non-aqueous secondary battery, and metal complex

Abstract

Provided are an electrolytic solution for a non-aqueous secondary battery containing an electrolyte, an organic solvent, and a metal complex represented by General Formula (I), a non-aqueous secondary battery in which the electrolytic solution for a non-aqueous secondary battery is used, and a metal complex. In General Formula (I), M represents a transition metal. k represents an integer of 0 or more, m represents an integer of 0 to 4, and n represents an integer of 1 or more. Here, k+n represents a valence of M. R1 represents an alkyl group, an aryl group, an alkoxy group, a carbonyl group-containing group, a sulfonyl group-containing group, or a halogen atom. R2 and R3 represent a hydrogen atom, an alkyl group, an aryl group, an alkoxy group, a carbonyl group-containing group, a sulfonyl group-containing group, or a halogen atom. L represents a monodentate ligand.
