Embodiment Construction
[0011] Referring to the accompanying drawings, the conductive carbon fiber felt 1 is welded together with the lead alloy rib 2, the rib 2 is embedded on the fiber felt 1, and the tab 3 is exposed (such as figure 1 ), in this example, the conductive carbon fiber felt is polyacrylonitrile-based carbon felt, with a grammage of 120g / ㎡.mm and a thickness of 2-4mm, which is pressed by winding and interwoven short polyacrylonitrile fibers. The tabs and the lead alloy ribs are made of lead-tin alloy, and the ribs 2 are staggered into rectangles (such as figure 2 ), the vertical spacing is 8mm, the horizontal spacing is 15mm, and the thickness is 2-4mm. The size of the grid is [thickness*width*height (total height)]3*146*130(150), or ribs 4 are staggered into a rhombus (such as image 3 ). Utilize the negative plate produced by the present invention to replace the negative plate of the original battery into several 12V60Ah (L2) starter batteries, the weight of the battery has droppe...
