摘要： The present invention relates to a method of preparing a lithium ion polymer battery which has a high capacity and a good cyclability as well as no exudation of liquid electrolyte. The lithium ion polymer battery according to the present invention is prepared by the steps of forming electrode films, laminating the electrode films on both surfaces of a grid or extended metal so as to improve the interfacial adhesion between the electrode films, forming a polymer electrolyte film composed of a polymer, an electrolyte solution, and a filler, and laminating the composite anode, the polymer electrolyte and the composite cathode. The activated composite anode/polymer electrolyte film/activated composite cathode is laminated to obtain a lithium ion polymer battery structure. The lithium ion polymer battery is vacuum-packaged using a vacuum packaging apparatus.
