  • Forming a lead acid bipolar battery electrode having a peripheral sealing frame and relevant product
    Patent number: 5667537
    Abstract: The method of forming the battery electrode includes providing two complementary half-frames of plastic material each having a substantially flat face delimited by an outer closed line and an inner closed line, where the inner and outer closed lines enclose the perimeter of the plate. Next, a plate is placed within a pressure forming mold between the two half-frames so as to enclose the perimeter of the plate between the outer closed lines and the inner closed lines. Then the mold is closed and heated to a temperature causing the plastic material of the half-frames to fuse and adhere continuously along the entire perimeter of the plate.
