METHOD FOR MANUFACTURING ALKALINE STORAGE BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a drying method for evenly drying individual parts on an electrode plate during an intermediate drying. SOLUTION: This manufacturing method for an alkaline storage battery has a rotating process for rotating a prescribed angle with a winding shaft of a winding core 11 of a porous sintered base plate wound in a spiral shape (sintered base plate coil) 10 as the center of rotation after a filling cycle is completed at least once. Rotating the prescribed angle about the winding shaft changes the drying atmospheric state (such as temperature distribution, flow and speed of hot air), at individual positions on the sintered base plate coil 10 from the drying atmospheric state during previous intermediate drying to prevent an uneven dried state of the porous sintered base plate impregnated with an acidic salt. In this way, generation of defects of the electrode plate such as uneven thickness of the electrode plate and the degraded strength of the sintered base plate is reduced to increase the yield of the electrode plate.
