POSITIVE ELECTRODE FOR ALKALINE SECONDARY BATTERY, MANUFACTURING METHOD OF POSITIVE ELECTRODE FOR THE ALKALINE SECONDARY BATTERY, AND THE ALKALINE SECONDARY BATTERY |
摘要 |
PROBLEM TO BE SOLVED: To provide a positive electrode for an alkaline secondary battery, capable of enhancing the welding strength of the conducive substrate and the collector. SOLUTION: The positive electrode for an alkaline secondary battery is provided with a conductive substrate having a three-dimensional structure; the collector 3 resistance-welded to the conductive substrate; and a positive electrode black mix for cell 2 retained by the conductive substrate and including an active substance, and in which is characterized that the collector 3 has a plurality of projections 4 and the sum of occupancy areas of the respective projection is within 10 to 60% of a facing area of the collector 3 and the conductive substrate. |
