ABSTRACT:
Ionic gel polymer electrolytes for rechargeable polymer batteries preferably are formed by dissolving a gelling agent into organic liquid electrolytes, and then gelling the precursor in situ at elevated temperature after pouring it into a battery case that contains a cathode, an anode and a separator. The gel polymer electrolytes exhibit excellent ionic conductivity of up to about 10−2S/cm and voltage stability for lithium rechargeable batteries. Most preferably, the gel polymer electrolyte is the reaction product of (A) a heterocyclic amine-group containing material (preferably a vinvlpyridine), and (B) halide or epoxy-group containing polymers, copolymers, oligomers or monomers that are capable of reacting with nitrogen-containing compounds, such as polymers, copolymers, oligomers or monomers containing alkylene halides or halomethyl group substituted aromatic units or at least one epoxy unit.
