MANUFACTURE OF CADMIUM ANODE PLATE FOR ALKALINE STORAGE BATTERY

摘要

PURPOSE:To increase rechargeability by adding microporous polyolefin short fibers containing magnesium compound to a paste type cadmium anode plate. CONSTITUTION:Microporous polyolefin short fibers containing fine magnesium compound powder and an active material mainly comprising cadmium oxide are kneaded with a binder solution to prepare paste. The paste is applied to a porous substrate and dried to obtain a desired plate. Even if active particles of a paste type cadmium anode plate are repeatedly charged and discharged or allowed to stand in a discharged state, the coarse growth of active material particles is prevented by the action of magnesium dissolved from the polyolefin short fibers. Therefore, rechargeability is increased.
