Nonaqueous electrolyte solution for secondary batteries and secondary battery provided with same

A nonaqueous electrolytic solution for a secondary battery which is used for a secondary battery, comprising:

• the following component (A) and the following component (B),
• component (A):
• at least one compound represented by the following general formula (1);
• and
• component (B):
• one boron complex salt represented by the following general formula (2), or
• at least one type of compound selected from the group consisting of boric acid esters, acid anhydrides, cyclic carbonates having an unsaturated bond, cyclic carbonates having a halogen atom, cyclic sulfonic acid esters, and amines represented by the general formula (3) and having an acetoacetyl group:
• in which the Mn+ represents an alkali metal ion, an alkaline earth metal ion, an aluminum ion, a transition metal ion or an onium ion, the R1 and R2 each independently represent any of a hydrocarbon group having 1 to 20 carbon atoms and a hydrocarbon group having 1 to 20 carbon atoms and having at least any one of a halogen atom, a heteroatom and an unsaturated bond, or the R1 and R2 represent any of a hydrocarbon group having 1 to 20 carbon atoms and a hydrocarbon group having 1 to 20 carbon atoms and having at least any one of a halogen atom, a heteroatom and an unsaturated bond, and are coupled to each other to form a cyclic structure, and the n represents a valence,
• in which the Mn+ represents an alkali metal ion, an alkaline earth metal ion, an aluminum ion, a transition metal ion or an onium ion, the X1 to X4 are each independent and one or a combination of two optionally selected from the X1 to X4 form a cyclic structure of —OOC—Y—COO, —O—Y—O— or —OOC—Y—O— in which the Y represents a hydrocarbon group having 0 to 20 carbon atoms or a hydrocarbon group having 0 to 20 carbon atoms and having a heteroatom, an unsaturated bond or a cyclic structure, or the X1 to X4 each independently represent a halogen atom, an alkyl group having 0 to 20 carbon atoms, an alkoxy group having 0 to 20 carbon atoms, an alkyl group having 0 to 20 carbon atoms and having at least any one of a halogen atom, a heteroatom and an unsaturated bond, or an alkoxy group having 0 to 20 carbon atoms and having at least any one of a halogen atom, a heteroatom and an unsaturated bond, and the n represents a valence,
• in which the R3 and R4 each independently represent any of a hydrocarbon group having 1 to 20 carbon atoms and a hydrocarbon group having 1 to 20 carbon atoms and having a halogen atom, a heteroatom or an unsaturated bond.
