POSITIVE ELECTRODE PLATE FOR LEAD-ACID BATTERY LEAD-ACID BATTERY AND METHOD OF MANUFACTURING POSITIVE ELECTRODE PLATE FOR LEAD-ACID BATTERY

摘要

The present invention relates to an electrode plate for lead storage batteries, capable of increasing initial capacity and lifespan performance of lead storage batteries. To this end, the electrode plate used in lead storage batteries comprises: a blanking grid (10) having a grid rib; and an electrode material (20). An edge part (15C) on a cross-section which is vertical to an extended direction of the grid rib of the blanking grid (10) is deformed, and density of the electrode material (20) after fired is greater than or equal to 4.1 g/cm^3.
