ABSTRACT:
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.
