The patent application (Publication Number: US20230402721A1) 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 a solid electrical joint into each hole, compressing the shaft to form heads on both surfaces of the frame, and filling the hole completely. Additional steps include placing lead sheets on each surface of the frame and welding at the electrical joints to enhance the connection. The method aims to inhibit crevice corrosion by welding at the edge portions of the electrical joints.
Furthermore, the patent application details the bipole frame assembly for a bipolar battery, which includes a bipole frame with positive and negative lead sheets, and electrical connections with heads on both surfaces of the frame. The electrical connections are made of a tin-lead alloy with less than 10% tin by weight. The assembly is designed to prevent crevice corrosion and ensure a secure connection between the lead sheets and the frame. Additionally, the patent application outlines the structure of a bipolar battery, which includes multiple bipole frame assemblies between positive and negative end frames. Each assembly consists of a bipole frame with lead sheets and electrical joints to facilitate the flow of electricity within the battery.
