Embodiment Construction
[0024] The present invention will be further described below in conjunction with specific embodiment:
[0025] Such as figure 1 The lithium battery 1, the blank foil of the positive electrode sheet and the blank foil of the negative electrode sheet of the lithium battery 1 are respectively used as the positive electrode conductive tab 2 and the negative electrode conductive tab 3 of the lithium battery 1, and the two conductive tabs are respectively located in the lithium battery. 1 at both ends.
[0026] In this embodiment, the combined flattening method of firstly ultrasonically flattening and then mechanically flattening is adopted for the conductive ears of the two ends of the lithium battery 1. Knead the negative pole flat.
[0027] Specifically, kneading mainly includes the following steps:
[0028] First, if figure 2 As shown, the ultrasonic kneading head 21 moves closer to the positive end of the lithium battery 1, and ultrasonically kneads the positive electrode ...
