EXAMPLE - A lithium cell with a capacity of 650 mAh was fabricated by assembling the cell using a positive electrode, a negative electrode, and an electrolyte precursor. The positive electrode was prepared by mixing lithium cobaltate positive active material, polyvinylidene fluoride binder, and a Super-P conductive agent in an N-methyl pyrrolidone solvent at a weight ratio of 94:3:3 to prepare positive active material slurry. The slurry was coated on an aluminum current collector and dried followed by pressing, thus obtaining a positive electrode. The negative electrode was prepared by depositing copper with a thickness of 10000 Angstrom on both sides of a polyethylene terephthalate film with a thickness of 15microns. After which lithium with a thickness of 20microns was deposited on both sides of the copper-deposited polyethylene terephthalate film to produce a negative electrode. The assembled cell was allowed to stand at 75degreesC for 4 hours. During the standing step, the electrolyte precursor solution was polymerized and hardened to produce a gel polymer electrolyte.
