Abstract
Bipolar lead/acid batteries are provided, having at least one cored bipolar battery plate. The bipolar battery plate comprises a core element having an active surface at each side thereof, with lead at the negative side and lead oxide at the positive side of the cored battery plate. The core element comprises titanium or other appropriate high barrier height material, at least at each surface thereof which faces the respective lead and lead oxide active surfaces. A molded polymer frame is provided around the bipolar plate, and appropriate negative and positive end plates are provided opposite the outer most positive or negative sides of the battery so as to provide a functioning battery structure. The polymer frame is such that it may be sealed against electrolyte leakage so that the electrolyte is confined within the structure by the battery frames. The battery frame may be vented so as to permit pressurized gas to flow from the battery when the pressure exceeds a predetermined pressure. The assembly of the plates and end plates may be accomplished using suitable bonding techniques for the plastic frame members, including pressure molding, ultrasonic bonding, thermal bonding, or the use of suitable adhesives.
