A support salt for a cell comprising a compound represented by the following formula (I) or (II): n n(NPA 1 2 ) 3 (I) n nA 1 3 P═N—P(═O)A 1 2 (II) n n(in the formulae (I) and (II), A 1 is independently NRLi or F, and at least one of A 1 s is NRLi, and R is a monovalent substituent) has an effect of suppressing combustion, and a non-aqueous electrolyte cell and a polymer cell using such a support salt considerably reduce the risk of ignition-fire and are high in the safety. |
