Abstract
An ionic conductive polymer gel for secondary battery includes an electrolyte salt component which includes a sulfonated derivative with formula (A): EQU LiX(SO.sub.2 R.sup.1).sub.n (A) wherein X is N, C, B, O or --C(R.sup.2).sub.m -- in which R.sup.2 is a hydrogen atom, an alkyl group having 1 to 12 carbon atoms, and m is an integer of 1 to 2; R.sup.1 a halogenated alkyl group having 1 to 12 carbon atoms; and n is an integer of 1 to 3; a non-aqueous solvent; and a polymer matrix prepared by polymerizing a polymerizable material comprising at least one acrylate monomer with a molecular weight of 1000 or less, in the presence of the electrolyte salt component and the non-aqueous solvent. A lithium-ion battery utilizes the ionic conductive polymer gel.
