PURPOSE: Provided are a secondary cell having superior flexibility and high cell characteristics and employing a polymer electrolyte, and a method for preparation thereof. CONSTITUTION: The secondary cell(1) has a cathode(4), a polymer electrolyte layer(3) and an anode(2), layered together. At least one of the cathode and the anode is formed by a sheet electrode comprised of a current collector, composed mainly of carbon fibers, and an electrode mixture carried thereon. A metal foil(5) is provided in sliding contact with the sheet electrode on the opposite side(9) of the sheet electrode with respect to the polymer electrolyte layer. An electrode terminal is taken from said metal foil. The cell device is sealed under a reduced pressure by an exterior member. The cathode includes a layer of a cathode active material capable of doping/undoping lithium ions. |
