PURPOSE:To increase the high-energy density by forming a thin film layer made of a carbon material on the surface of manganese dioxide grains used as a positive electrode material. CONSTITUTION:A thin film layer made of a carbon material is formed on the surface of manganese dioxide grains used as a positive electrode material. If the manganese dioxide quantity is made a fixed value and the packing density of the positive electrode black mix 1 is made the fixed value of the normal black mix reference, a volume gain is obtained for the deposition-processed manganese dioxide 1. That is, if the positive electrode electric capacity is made a fixed value, the deposition-processed manganese dioxide can output electric energy with a volume smaller than that of the normal black mix. Accordingly, the energy density for the unit volume is increased. |
