Abstract

PURPOSE:To enhance the performance of an organic electrolyte battery by improving the conductivity and the liquid-holding ability of a positive electrode by combining a positive active material made of a metal oxide or the like with a carbon black which is used as a conductive agent and has a hollow shell-like granular structure. CONSTITUTION:After manganese dioxide is mixed with a conductive agent consisting of a carbon black such as Koetchen black which has a hollow shell-like granular structure consisting of a thin film of concentrated graphite crystals, fine-hole peaks at the radiuses 8Angstrom and 20Angstrom and a porosity of 69.3%, a conductive agent is added to the mixture, and thus prepared mixture is pressed and molded so as to make a positive electrode 3. Then an organic electrolyte battery is constituted by combining the positive electrode 3 with a separator 5 and a negative electrode 4. As a result, since the distances between the particles are short due to the hollow shell like structure, the conductivity of the positive electrode 3 can be enhanced due to tunnel effect. Besides, due to the high porosity of the particles, the liquid-holding ability of the positive electrode 3 can be increased. Consequently, the high-rate electric-discharge characteristic and the low-temperature electric-discharge characteristic of the battery can be improved.
