PURPOSE:To reduce the thickness and weight of a collector and make the collector easy to curve by using the foil or sheet of lead or a lead alloy as the collector. CONSTITUTION:An electrode plate 1 for lead-acid battery has an active material 3 on one surface of a collector 2 consisting of the foil or sheet of lead or a lead acid in the lateral direction of the collector, the active material being applied in lattice at longitudinal determined intervals. The energy density can be thus increased, and the electrode 1 is easy to curve by the presence of non- application parts 2a, increasing freedom. When a positive electrode plate 1A and a negative electrode plate 1B are combined through an electrolyte holding body 5, the reacting area is increased to increase the capacity. |
