Additive A, which is at least one selected from the group consisting of the compound represented by the following formula (A), and addition, which is at least one selected from the group consisting of lithium monofluorophosphate and lithium difluorophosphate. A non-aqueous electrolyte solution for a battery containing agent B and additive C, which is at least one selected from the group consisting of compounds having a sulfur-oxygen bond. In the formula (A), R 1 represents a fluorine atom or a fluorinated hydrocarbon group having 1 to 6 carbon atoms, and R 2 to R 4 independently represent a hydrogen atom, a fluorine atom, and 1 to 6 carbon atoms. It represents a hydrocarbon group of 6 or a fluorinated hydrocarbon group having 1 to 6 carbon atoms. |
