Abstract:
A polymer rechargeable battery comprising:a current collector for a positive electrode, said current collector being a metal-foil base material and having a number of throughholes formed by etching, wherein the remaining portion is not etched; a current collector for a negative electrode, said current collector being a metal-foil base material and having a number of throughholes formed by etching, wherein the remaining portion is not etched; a positive electrode material laminated on the current collector for a positive electrode; a negative electrode material laminated on the current collector for a negative electrode; and a separator made of a polymer containing an electrolyte solution, said separator being obtained by replacing a plastisizer contained in said polymer with an electrolyte solution, said separator being sandwiched by said positive electrode material and said negative electrode material.
