Application: Bipole frame with improved solid electrical connection and bipolar batteries including the same (Patent ID: US20230402721A1)
The patent filed by EnerSys describes a method for assembling a bipole frame assembly for a bipolar battery. The method involves providing a bipole frame with through holes, inserting a shaft of an electrical joint into each hole, compressing the shaft to form heads on both surfaces of the frame, and filling the hole completely with the shaft. Additional steps include placing lead sheets on both surfaces of the frame and welding at the electrical joints to enhance connections.
Furthermore, the patent details the composition of the electrical joints, specifying the use of a tin-lead alloy with less than 10% tin by weight. The bipole frame assembly includes positive and negative lead sheets, with electrical connections at each through hole. The heads of the electrical connections are larger than the diameter of the holes, and the positive lead sheet is on the first heads while the negative lead sheet is on the second heads. The patent also covers the construction of a bipolar battery using these bipole frame assemblies between positive and negative end frames.
