A lead-acid battery construction includes positive electrode means (37) and negative electrode means (39, 40) supported in contact with separator means (42) containing an electrolyte. The positive electrode means (31) is gridless and is formed with reacting PbO2 portions (66) and non-reactiong PbO2 portions (64) which carry a required electric current through the positive electrode means during charging and discharging. |
