摘要:
A method for stabilizing a solution that contains LiPF6 by increasing thermal stability of LiPF6 without 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 LiPF6 contains a phosphoric acid ester amide in such an amount that the molar ratio of the phosphoric acid ester amide relative to LiPF6 is 0.001-2.

[Problem] To provide a fluorine-containing phosphate ester-amide which has high flame retardancy such as exhibiting flame retardant effects at a small quantity of addition, and sufficient hydrolysis resistance.[Solution] A fluorine-containing phosphate ester-amide represented by general formula (1). (In the formula, R1 and R2 are the same or different and represent a branched or linear alkyl group having 1 to 20 carbon atoms in which at least one carbon bonded to a nitrogen atom is a secondary or tertiary carbon, wherein R1 and R2 may have a substituent group selected from the group consisting of an alkoxy group, a hydroxy group, an amino group, a methyl amino group, an ethyl amino group, a dimethyl amino group, diethyl amino group and a fluorine atom. In addition, R1 and R2 may be bonded together to form a five- to eight-membered cyclic structure. X and Y are the same or different and represent a hydrogen atom or a fluorine atom, and n and m represent an integer of 1 to 6.)
