  • Integrated bipolar electrode, preparation method and use thereof
    Patent number: 11380903
    Abstract: An integrated bipolar electrode includes a laminated structure and a bipolar plate. The laminated structure is formed by interconnecting an anode active material layer with a cathode active material layer. The bipolar plate is sandwiched in a hollow cavity of the laminated structure. Side surfaces of the laminated structure are provided with a sealing layer for mating with a bipolar electrode fixing frame to prevent an anolyte and a catholyte from permeating into each other. The anode active material layer and the cathode active material layer in the integrated bipolar electrode are directly connected. A contact resistance between the anode active material layer and the cathode active material layer is quite low, and a battery prepared finally has better performances.
