Title:
【発明の名称】アルカリ蓄電池用ペースト式カドミウム負極の製造法
Document Type and Number:
Japanese Patent JP3317105
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a high performance paste type cadmium negative electrode whose partial charging process is ovbiated by agitating paste by adding collected carbon fiber to an active material mainly composed of prescribed cadmium type powder, and forming the negative electrode by sticking it to a core material. SOLUTION: Paste is formed by adding carbon fiber collected by low molecular nylon to an active material mainly composed of one or more kinds among metallic cadmium powder, cadmium oxide powder and cadmium hydroxide powder. When this paste is agitated, the collected carbon fiber is uniformly dispersed, and when it is painted on a core material, a negative electrode in which a conductive matrix skeleton of mrtallic cadimium powder is formed can be provided. Therefore, a high performance paste type negative electrode whose partial charging process is obviated and short circuit occurrence rate is low can be provided.
