A support salt for a cell comprising a compound representednby the following formula (I) or (II):n (NPA 1 2 ) 3 n A 1 3 P=N-P(=O)A 1 2 n(in the formulae (I) and (II), A 1 is independently NRLi or F, and atnleast one of A 1 s is NRLi, and R is a monovalent substituent) has anneffect of suppressing combustion, and a non-aqueous electrolyte cellnand a polymer cell using such a support salt considerably reduce thenrisk of ignition-fire and are high in the safety. |
