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.
An integrated bipolar electrode, comprising a laminated structure and a bipolar plate, the laminated structure being formed by interconnecting an anode active material layer with a cathode active material layer, the bipolar plate being sandwiched in a hollow cavity of the laminated structure, side surfaces of the laminated structure being 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, wherein a material of the anode active material layer is same as a material of the cathode active material layer, the laminated structure is formed by folding a single piece of sheet in half, and the bipolar plate is arranged in the hollow cavity of the laminated structure.
