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

摘要

A positive electrode plate for a lead-acid battery includes: a punched grid having grid crosspieces; and a positive electrode material. A corner portion of the grid crosspiece of the punched grid in a cross section perpendicular to an extending direction of the grid crosspiece is deformed, and a density of the positive electrode material after being subjected to formation is 4.1 [g/cm 3 ] or more.
