Abstract
Abstract This invention relates to improvement in an organic electrolyte battery employing a light metal as an anodic material; organic electrolyte; and CuO as a cathodic material. By using, as the cathodic material, the solid solution of alkali metal oxide and CuO as a mother substance, the delivered volumetric energy density of the battery is fairly increased.
