ALKALINE STORAGE BATTERY NON-SINTERING CADMIUM NEGATIVE ELECTRODE

Title:

ALKALINE STORAGE BATTERY NON-SINTERING CADMIUM NEGATIVE ELECTRODE

Document Type and Number:

Japanese Patent JP2007273416

Kind Code:

A

Abstract:

To provide a chemically-unconverted non-sintering cadmium negative electrode, whose capacity density is raised further than the conventional types without decrease in the active substance utilization rate, even if active substance density is enhanced.

The non-sintering cadmium negative electrode is obtained, by forming an active substance layer on an electrode substrate by applying an active substance comprising cadmium oxide and cadmium metal on the electrode substrate. A conductive agent, such as nickel metal, is contained in the active substance. By making a conductive agent contained in the active substance, in such a way as not to bring about decrease in the utilization rate of the active substance, even if the density of the active substance is set as high as 3.4 g/cm3or higher, capacity density than can be enhanced more than those of conventional cadmium electrodes.
