MANUFACTURING METHOD OF CATHODE MIXTURE FOR BATTERY, CATHODE MIXTURE FOR ALKALINE BATTERY AND ALKALINE BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a cathode mixture for a battery capable of enhancing molding density without increasing the mechanical load.SOLUTION: After a mixture containing a cathode active material and a conductive agent is rolled under reduced pressure by a roller compactor, it is granulated by a granulator. Then, screening is carried out to obtain cathode mixture granules with a desired particle size, and the cathode mixture granules are put under pressure molding under reduced pressure by a pressure molding machine and thereby manufacturing a ring-shaped cathode mixture.
