PURPOSE: A coin-type lithium polymer battery is provided, to improve the capacity, the cycle lifetime characteristic and the stability of the battery and to allow the battery to be manufactured easily. CONSTITUTION: The coin-type lithium polymer battery comprises a laminate formed by laminating a negative electrode(21) whose both sides are adhered to a polymer electrolyte(23) and positive electrode(22) whose both sides are adhered to a polymer electrolyte(23), separately or together. The polymer electrolyte(23) is a gel-type polymer electrolyte containing an organic solvent electrolyte or a porous polymer membrane containing an organic solvent electrolyte. Preferably the gel-type polymer electrolyte is at least one selected from the group consisting of a polyacrylonitrile-based polymer, a polyvinylidene fluoride-based polymer, a polymethyl methacrylate-based polymer, a polyethylene oxide-based polymer, a polyethylene glycol-based polymer, a polyethylene glycol diacrylate-based polymer, a polyethylene glycol dimethacrylate-based polymer and a polyethylene glycol trimethacrylate-based polymer; and the porous polymer membrane is at least one selected from the group consisting of a polyvinylidene fluoride-based porous polymer, a polyvinylidene chloride-based porous polymer and a polyacrylonitrile-based porous polymer. |
