A non-aqueous electrolyte solution for a battery includes: an additive A which is a compound represented by formula (I); and an additive B which is at least one selected from the group consisting of an aromatic compound having at least one of a halogen atom or an alkyl group and a carbamate, and which is a compound other than carbonates or a cyclic sulfates. In formula (I), R1 represents a group represented by formula (II) or a group represented by formula (III) and R2 represents H, a C1-6 alkyl group, a group represented by formula (II), or a group represented by formula (III); or R1 and R2 represent groups which combine to form a benzene ring or cyclohexyl ring. In formula (II), R3 represents a halogen atom, a C1-6 alkyl group, a C1-6 alkyl halide group, a C1-6 alkoxy group, or a group represented by formula (IV).; |

1. A non-aqueous electrolyte solution for a battery, comprising:
an additive A which is a cyclic sulfate compound represented by the following formula (I); and an additive B which is at least one selected from the group consisting of an aromatic compound having at least one of a halogen atom or an alkyl group and a carbamate compound, and which is a compound other than a carbonate compound and a cyclic sulfate compound: wherein, in formula (I), R1 represents a group represented by formula (II) or a group represented by formula (III) and R2 represents a hydrogen atom, an alkyl group having from 1 to 6 carbon atoms, a group represented by formula (II) or a group represented by formula (III), or R1 and R2 represent groups which combine to form a benzene ring or a cyclohexyl ring together with a carbon atom to which R1 is bonded and a carbon atom to which R2 is bonded; in formula (II), R3 represents a halogen atom, an alkyl group having from 1 to 6 carbon atoms, a halogenated alkyl group having from 1 to 6 carbon atoms, an alkoxy group having from 1 to 6 carbon atoms, or a group represented by formula (IV), and wavy lines in formula (II), formula (III), and formula (IV) represent bonding positions; and in a case in which there are two groups represented by formula (II) in the cyclic sulfate compound represented by formula (I), the two groups represented by formula (II) may be the same as or different from each other. |
