PURPOSE:To obtain an excellent electric discharge characteristic by providing a positive electrode containing cobalt iodide as a positive active material, on one side surface of a solid electrolyte, on the other side surface of which a negative electrode containing Li or an Li alloy used as a negative active material is provided. CONSTITUTION:A negative electrode 1 containing Li or an Li alloy used as a negative active material, is provided on one side surface of a solid electrolyte 2 made of LiI, Li3N, Li, Na-beta-Al2O3, yLi3N-(1-y)LiCl(0<y<1), Li-beta-Al2O3 or the like. A positive electrode 3 is provided on the other side surface of the electrolyte 2, and contains both a positive active material consisting of cobalt iodide (Col2) and an electron-conducting auxiliary agent such as the powder of a metal such as Ni, Ag, Cu or Pb. In such a battery containing cobalt iodide as a positive active material, the product of electric discharge reaction gives only a relatively small internal resistance, and the increase in the internal resistance caused with the progress of electric discharge reaction is not so significant. |
