PURPOSE:To obtain a structure of positive electrode-active material which can be easily treated in industry and is dense in high energy by heating a structure which is composed by charging an opening of copper network body with the mixture of copper compound and organic high molecular compound expressed by the formula Cux, Mo6S8-y (x being 2 to 4 and y 0 to 0.25 in the formula) in the gas including sulfur. CONSTITUTION:The structure composed by charging an opening of copper network body with the mixture of copper compound and organic high molecular compound expressed by the formula Cux, Mo6S8-y (x being 2 to 4 and y 0 to 0.25 in the formula) in the gas including sulfur to produce the structure of positive electrode active material. The mixture of copper chevrel compound is composed to be powder and its grain size is less than 300 meshes. As for the organic high molecular compound, such as 1, 4-polybutadiene, natural rubber, polyisoprene, copolymer of styrene-butadiene, copolymer of acrylonitrile- butadiene and copolymer of styrene-butadiene-styreneblock are employed and for the copper network body, woven or unwoven cloth formed with copper at its surface is employed. Furthermore, the opening ratio is set in the range of 25 to 60%. |
