description An object of the present invention is to provide: a production method for commercially advantageously producing lithium difluorophosphate or an electrolyte solution containing the lithium difluorophosphate, the lithium difluorophosphate serving as an additive useful for improving performance of a nonaqueous electrolyte battery; and a nonaqueous electrolyte battery employing the electrolyte solution for the nonaqueous electrolyte battery which solution contains the lithium difluorophosphate produced by the production method. To provide an electrolyte solution for a nonaqueous electrolyte battery which solution contains lithium difluorophosphate, in such a manner as to produce lithium difluorophosphate in the electrolyte solution by reacting a halide other than a fluoride, LiPF6 and water in a nonaqueous solvent, the lithium difluorophosphate serving as an additive useful for improving performance of the nonaqueous electrolyte battery.
