Abstract
The invention relates to a composition for preparing a gel polymer electrolyte, comprising: (1) a prepolymer; (2) a lithium salt; (3) an organic solvent; (4) a cross-linking agent; (5) an initiator; (6) optionally a monomer; and (7) optionally an additive; wherein the prepolymer comprises polyamides, polyimides and their combination. The invention also relates to a gel polymer electrolyte obtained by polymerization, especially in-situ polymerization of the composition and lithium-ion batteries employing the gelpolymer electrolyte, and a method of preparing the ge polymer electrolyte.
