PURPOSE: To manufacture of Cd negative pole having high strength and to improve the cell characteristic, by adding the short synthetic resin fiber applied with Cd galvanization into the paste then applying said paste onto the porous core metal thereafter applying the Cd galvanization.
CONSTITUTION: The synthetic resin resin short fiber applied with Cd galvanization is dispersed into the paste composed of CdO added with the binder. Then said paste is applied onto the porous core metal and dried to produce the yet- formed plate. Then said plate is applied with Cd galvanization and water washed and dried. The conductive network of metallic Cd is formed in Cd negative pole thus obtained, resulting in the improvement of the oxygen gas absorbing characteristic of the negative pole active substance, the improvement of the utilization of the negative pole active substance and the improvement of the cycle life.
