ABSTRACT:
A precursor composition capable to form a solid-state electrolyte having good ion conductivity and high heat-resistance, by simple curing procedure, comprising; (A) a polymerizable ion pair compound represented by formula I, (B) a cross-linker having two or more unsaturated groups co-polymerizable with the polymerizable ion pair compound (A), and (C) non-polymerizable ion pair compound. Each of R1, R2, R3, R4, R5 and R6 represents hydrogen atom, alkyl or aryl group having 1-12 carbon atoms; and each of R7 and R8 represents alkyl or aryl group having 1-12 carbon atoms. X designates either of halogen atom, AlCl4−, PF6−, BF4−, bis (oxalato) borate anion, Rf1SO3−, (NC)2N−, (Rf2Y)2N−, (Rf2Y)3C−, and (Rf2Y)2C−Q, where Rf1designates perfluoro alkyl or aryl group having 1-8 carbon atoms; each Rf2designates fluorine atom, perfluoro alkyl or aryl group having 1-8 carbon atoms; Y designates —SO2—or —PO—Rf2; and Q designates —H or —CO—Rf2
