Therefore, the forming of the serrated grid line is accurate and quick, and the production efficiency is high.
In some embodiments, the gate line formation groove has a depth of 30um to 100um and a width of 20um to 60um.
As shown in fig. 1, taking an example in which the length direction of the prefabricated serrated gate lines coincides with the length direction of the battery piece 4, the length direction of the battery piece 4 is the a direction, the height of the serrated gate lines means the dimension of the serrated gate lines in the thickness direction of the battery piece 4, i.e., the B direction, and the thickness of the serrated gate lines means the dimension of the serrated gate lines in the width direction of the battery piece 4. At this time, the height of the serrated grating line is equal to the depth of the grating line forming groove, and the thickness of the serrated grating line is equal to the width of the grating line forming groove. Therefore, the width and the height of the solidified conductive strip 3 are guaranteed to be consistent with those of the prefabricated serrated grid line, and then the bevel is only needed to be cut in the subsequent cutting process, so that the production efficiency of the serrated grid line is improved.
