A thin metal-halogen cell which comprises an electroconductive substrate, an anode active material layer of thin metal film formed on the base plate, a solid electrolyte layer formed on the anode active material, a cathode active material layer comprising a halogen, adhesive and carbonaceous powder, and an electroconductive plastic film, the latter two being laminated on the solid electrolyte layer in this order can be produced by using a step of forming thin films such as vacuum evaporation coating or sputtering and a step of laminating by using an adhesive. Thus, ultra-thin cells having high power and a thickness of 1 mm or less can be produced easily and inexpensively. When a separator and a barrier layer are sandwiched between the cathode active material layer and the solid electrolyte layer, shelf life of the cell is improved remarkably.
A thin metal-halogen cell which comprises an electroconductive substrate about 50 microns to 0.5 mm in thickness, a metal film anode active material layer of about 1 to 100 microns formed on the substrate, a solid electrolyte layer of about 1 to 20 microns formed on the anode active material, a cathode active material layer of about 50 microns to 0.5 mm thickness and comprising a halogen, an adhesive and carbonaceous powder, and an electroconductive plastic film about 50 microns to 0.5 mm thick, the cathode active material layer and the electroconductive plastic film being laminated on the solid electrolytic layer in this order.
