PURPOSE:To aim at increasing of absorptivity for oxigen gas at cadmium negative electrode so as to make the large current charge possible by forming a group of electrode plates in a way as making the conductive side of a separator face the negative electrode, and opposite side of the separator act positive electrode. CONSTITUTION:Using a separator on whose one side is formed alkali resistant conductive layer, and the conductive layer side is made to face a negative electrode, and opposite side of the separator is made to act as a positive electrode, thus the battery in the caption is formed. By this, the conductive layer of the separator is made as a conductive matrix on surface of the negative electrode so that the metallic cadmium formed on the negative electrode in charging the battery may be concentrated on the surface of the negative electrode. Thus, the oxigen gas generated from the positive electrode in over charging is effectively absorbed and the large current charging (short time charging) can be achieved. |
