PURPOSE:To improve the discharge characteristic and the cycle characteristic of a cell and restrict rise-up of the internal pressure of the cell by applying metallic plating where water repellent resin is dispersed in the carrier surface. CONSTITUTION:Metallic plating 2 where such water repellent resin 3 as polyterafluoroethylene is dispersed is applied to the surface of a carrier 1 used for a hydrogen storage alloy electrode. Resultantly, the conductivity of the carrier 1 is increased by a metal making the matrix of metallic plating 2, and high water repellency is provided on the carrier 1 by the water repellent resin 3 dispersed in the metallic plating 2, so that the conductivity and water repellency of the carrier 1 can be improved. It is thereby possible to improve the discharge characteristic and the cycle characteristic of an alkaline secondary cell and also control rise-up of the internal pressure of the cell. |
