Abstract
A lead acid bipolar battery comprises a plurality of bipolar electrodes stacked between two monopolar end collectors in turn closed by end plates. All electrodes have respective plastic stiffening edge frames. The spacer frames are interposed between the electrodes to support the electrode frames. The spacer frames contain electrolyte supporting material and have electrolyte inlet bores and gas outlets. The stack is surrounded by a layer of eventually strengthened polyolefin material which seals the stack and provides a housing for the battery.
