Embodiment 1
[0021] Use industrial aluminum plate with a thickness of 1mm to make an anode plate core 1 with an overall dimension (length×width) of 1025mm×630mm, which is slightly smaller than the traditional standard anode plate, and then use a 10mm thick industrial aluminum row to make an anode plate core 1 with a length×width of 1054mm×50mm Conductive beam 2, at one end of the conductive beam 2, cut off a copper lug interface end 3 with a length × width × thickness of 120 mm × 8 ~ 10 mm × 25 mm, and use the current aluminum-copper composite method on the cut aluminum conductive beam interface A piece of conductive copper tab 4 with a length×width×thickness of 120mm×12-16mm×28mm is prepared from the terminal 3 . The aluminum core board 1 is welded at the center position of the length direction of the conductive beam 2 to form a whole. After the welded core board 1 and the conductive beam 2 are subjected to surface removal treatment in the prior art, a layer with a thickness of A tin tran...
Embodiment 2
[0023] After the industrial aluminum plate with a thickness of 0.4 mm is used to draw mesh 7, it is cut according to the required capacity lead storage battery grid dimensions (length × width) and prepared into a complete grid shape with frame 8 and tabs 9, As the aluminum core, after the surface of the aluminum core grid is pretreated, a layer of 40 μm antimony transition alloy layer 10 is formed on it, and then the outer surface of the antimony transition alloy layer 10 is coated with a layer of Pb- Sb-As-Se lead alloy layer 11, and the grid meshes are not filled with lead alloy, as shown in Fig. 4, Fig. 5 and Fig. 6.
