Abstract: A bipolar battery includes a plurality of cell members, each including a positive electrode having a positive active material layer, a negative electrode having a negative active material layer, and an electrolyte layer interposed between the positive electrode and the negative electrode. The bipolar battery also includes a plurality of frame units respectively forming a plurality of cells respectively incorporating the plurality of cell members. Each of the plurality of frame units is a frame unit made of a light transmissive resin material. Two of the frame units made of the light transmissive resin material adjacent in a stacking direction of the cell members are welded and joined at a welded portion via a joining member made of a light absorbing resin material. This configuration can provide a bipolar battery capable of reliably preventing electrolytic solution leakage out of a cell by means of a simple seal structure.

Abstract: A bipolar electrode for a bipolar lead-acid battery includes a substrate (bipolar plate) in which a through hole for conduction is formed, a positive electrode bonded to one surface of the substrate with an adhesive layer, and a negative electrode bonded to another surface of the substrate with an adhesive layer. The substrate has, on each of the one surface and the other surface, a projecting portion surrounding an outer circumference of the through hole as an entry avoidance structure. The bipolar lead-acid battery includes multiple layers of the bipolar electrodes. By preventing adhesive from entering a through hole for conduction formed in a bipolar plate, the reliability of joining between a positive-electrode lead layer and a negative-electrode lead layer is improved.

Abstract: A bipolar battery includes a plurality of cell members and a plurality of frame units configured to form a plurality of cells individually housing the plurality of cell members. Each of the plurality of frame units has joining surfaces facing each other in the stacking direction of the cell members, which are joined to each other by a joining material. On outer side surfaces of the frame units adjacent to each other in the stacking direction, a groove is formed which communicates between the joining surfaces to be joined and opens to the outer side surfaces. A water sealing material is disposed in the groove. This arrangement provides a bipolar battery capable of reliably preventing an electrolyte from leaking out of a cell by a simple seal configuration.
