A polymer electrolyte is provided that uses an ionic liquid. The electrolyte generally has a formula of IL-(ZRnXq-n)v (MYm)w, where Z is Al, B, P, Sb, or As; R is an organic radical (alkyl, alkenyl, aryl, phenyl, benzyl, amido); X and Y are halogens (F, CI, Br, I); M is an alkali or alkaline metal. IL is an ionic liquid that contains an organic cation (e.g. 1 -alkyl-3methylimidazolium, 1 -alkylpyridinium, N-methyl-N-alkylpyrrolidinium, ammonium salts) and a halide anion (F", CI", Br", or T). |
