摘要： The present invention provides a simple method for producing a difluorophosphate from a source material, the difluorophosphate being useful as additives for nonaqueous electrolyte solutions for secondary batteries. In the method, a source material containing a carbonate and/or a borate is allowed to react with a source gas which contains P and F and which may further contain O as required. The source material may contain lithium carbonate. The source gas may be produced by decomposing LiPF6. The source gas may be produced in such a manner that LiPF6 and lithium carbonate are mixed and then subjected to reaction. The nonaqueous electrolyte solution contains the product obtained from the reaction.
