Abstract
A method for stabilizing a solution that contains LiPFby increasing thermal stability of LiPFwithout changing the structure thereof; an electrolyte solution for nonaqueous secondary batteries, which has increased thermal stability; and a nonaqueous secondary battery which has increased thermal stability. The solution containing LiPFcontains a phosphoric acid ester amide in such an amount that the molar ratio of the phosphoric acid ester amide relative to LiPFis 0.001-2.
