PURPOSE:To improve the over-discharge characteristic by inter posing a conductive layer between an anode active mass layer and the anode collector made of lead or lead alloy, in a so-called retainer-type lead storage battery in which the mount of electrolyte is limited to prevent the existence of the electrolyte in free form. CONSTITUTION:The active mass formed into paste form by kneading PbO and water is rolled to the active mass sheet having a thickness of 1.0mm., and conductive powder is applied onto one-side surface of the sheet to form the conductive thin layer having a thickness of 100-200mu. An anode plate 10 is obtained by attaching the active mass sheet onto the both surfaces of an anode collector 12, with the conductive thin layer of the sheet inside. Therefore, the anode plate 10 is constituted so that the conductive layer 13 is interposed between the anode active mass lauer 11 and the anode collector 12 made of lead or lead alloy, and thus formation of irreversible PbSO4 layer is suppressed and the overdischarge characteristic is improved. |
