Abstract
The present invention provides a gel polymer electrolyte battery which uses a polymerizable electrolyte polymerized within the battery case to form a gel polymer electrolyte without the addition of a polymerization initiator. The electrolyte of this invention can be produced by simply adding organic monomer to a conventional liquid electrolyte. The polymerizable electrolyte comprises a nonaqueous solvent, an electrolyte salt, and an organic monomer selected from the group consisting of vinyl ether and epoxide. Methods of making gel polymer electrolyte as well as polymer electrolyte battery are provided.
