PURPOSE:To improve the highly efficient discharge property of a cell, by using a zinc oxide powder mixing 20 to 80 wt% of the first zinc oxide powder and 80 to 20 wt% of the second zinc oxide powder which have specified particle diameters respectively. CONSTITUTION:A zinc oxide powder is made by mixing 20 to 80 wt% of a zinc oxide powder with the particle diameter 0.1 to 0.5mum, and 80 to 20 wt% of a zinc oxide powder with particle diameter less than 0.1 mum. To the 85 wt% of such a zinc oxide powder, 10 wt% of metallic zinc powder and 5 wt% of cadmium oxide powder are added, and moreover, water and PTFE are added. They are mixed and kneaded to make an active substance paste. The active substance paste is pressed to attach or the like to the both sides of a nickel mesh to produce a zinc electrode. In such a way, the highly efficient discharge property of a cell can be improved. |
