Patent abstract
A cathode, an anode and a porous film are first provided. Then, the cathode and anode are aligned with the porous film and a part of the cathode and a part of the anode are fixed to said porous film. Then, the cathode, anode and porous film are immersed in a liquid electrolyte. Finally, the cathode and anode are integrated with the porous film by compression. With this process, it is possible to produce a thin and lightweight polymer secondary battery or other secondary batteries with ease yet at low cost.
