NOVELTY - The manufacturing method involves forming an electrode with porous material that has spaces; filling substantially all of the spaces with liquid; and after filling substantially all of the spaces with liquid, placing a polymer electrolyte film on the electrode. Gas is evacuated from substantially all of the spaces before filling with a polymer electrolyte film.    USE - Method of manufacturing lithium-ion polymer battery.    ADVANTAGE - Ion transport inefficiencies due to the poor interfacial contact between the solid polymer electrolyte film and the electrode materials are reduced by activating the electrodes prior to coating the polymer electrolyte film thereon. The combination of liquid electrolytes, which may be loaded in the porous spaces of the electrodes during activation, and the gel-polymer electrolyte film, which may be interposed between the electrodes and block communication between two different electrolytes used to separately activate anodes and cathodes, improve ion transport through the interfacial contact. The electrode/electrolyte interface may be well extended into the porous electrode structure because the electrodes may be well wetted and soaked from the preliminary activation, thereby forming a continuous network between the gel electrolyte and the electrodes. The interfacial impedance is reduced; giving the resultant battery improved cyclability, ability to accept high current rates and improved safety. The polymer electrolyte film may have a micro porous structure, having no voids through which electrical contact between electrodes could be established, thereby, the micro porous film serves as a good insulator between anodes and cathodes.
