Title: Paste type cadmium negative electrode
Inventor: KAIYA HIDEO
IPC: H01M10/52
Filed: 1984-06-19
Abstract: PURPOSE:To obtain a high performance paste type cadmium negative electrode whose oxygen gas absorption ability is good and no formation is required by applying a nickel plating layer on the surface of a plate prepared by filling an active material mixture mainly comprising cadmium oxide powder and metallic cadmium powder in a conductive core. CONSTITUTION:When metallic cadmium powder equivalent to the amount reduced by preliminary charging is mixed for eliminating formation, cadmium powder is dispersed between cadmium oxide or cadmium hydroxide whose conductivity is low. Since electrical contact between these materials is not so good, utilization in charge and discharge is low. By forming a conductive metal layer on the surface of negative plate by electrical palting or chemical plating, metallic cadmium is produced on a core and on the metal layer of the plate by charging to form a matrix with the cadmium powder dispersed in the active material. Thereby, utilization of metallic cadmium powder is increased, and absorption of oxygen gas evolved during overcharging is increased since distribution of metallic cadmium on the surface of the plate is increased.
