PURPOSE:To keep the charged valtage constant and prevent it from rising above the value by providing a negative electrode made of a light metal, an organic electrolyte made of at least one solvent and at least one solute, and a positive electrode arranged with a layer made of polyphenylene or its derivative on the surface. CONSTITUTION:A negative electrode 1 made by punching a lithium plate is pressed to the inner bottom of a negative electrode can 10. A positive electrode 2 is made by molding under pressure the mixture powder of 90wt% of molybdenum trioxide as an active material, 6wt% of acetylene black as a conductive agent, and 4wt% of fluororesin powder as a binding agent, and is arranged at the inner bottom of a positive electrode can 20. A polyphenylene layer 3 arranged on the surface of the positive electrode 2 is made by molding under pressure the polyphenylene powder. In addition, a separator 4 made of polypropylene nonwoven fabric is impregnated with an organic electrolyte made by dissolving 1mol/(1) of lithium perchlorate as a solute in a mixed solvent of propylene carbonate and 1,2 dimethoxyethane. |
