Publication number: 20230361312Abstract: Provided is a bipolar storage battery in which an electrolytic solution is less likely to enter the interface between a positive electrode and an adhesive layer. Thus, battery performance is less likely to be reduced even if growth occurs in the positive electrode due to corrosion by sulfuric acid contained in the electrolytic solution. The bipolar storage battery includes a bipolar plate including a support column configured to support adjacent plates to each other when stacked, a positive current collector bonded to one surface of the bipolar plate by an adhesive, a positive active material layer placed on the positive current collector, a negative current collector bonded to another surface of the bipolar plate by an adhesive, a negative active material layer placed on the negative current collector, and a cover plate covering a peripheral edge portion of the positive current collector.Type: ApplicationFiled: July 21, 2023Publication date: November 9, 2023Inventors: Kenji Hirota, Yoshinobu Taira, Hideo Nishikubo, Kenichi Suyama, Hiroki Tanaka, Yasuo Nakajima, Akira Tanaka
