PURPOSE:To provide a silver oxide battery having decreased internal resistance and increased discharge capacity by forming silver layer on the particle surface by chemically reducing the surface of secondary particle of silver oxide, and assembling a battery using this particle as a positive active mass, and conducting pre-discharge of a battery. CONSTITUTION:Secondary particle of silver oxide having a particle size of 100-400mum is preferable in this invention. This particle is prepared in such a way that primary particle of silver oxide having a particle size of 1.5-10mum is mixed with water, and after moisture is controlled adequately, the mixture is granulated, and balled if necessary, to form the secondary particle. The chemical reduction of the surface of the silver oxide secondary particle is conducted in such a way that particle is dipped in a solution prepared by dissolving hydrezine acting as a reducing agent in ethyl alcohol. Pre-discharge is conducted at constant load discharge or constant current discharge or ac discharge. By this procedure, a battery having decreased internal resistance is provided. |
