In order to improve the energy density and safety of the battery, a composite current collector obtained by compounding a high polymer film and a metal plating layer has gradually attracted attention. In the welding of welding parts such as composite current collectors, the composite current collector has low heat resistance, so the traditional technology adopts a switching welding mode, that is, a layer of traditional foil is added between the composite current collectors, and the traditional foil is used as a switching body. The switching welding is performed by an ultrasonic welding device under high-frequency vibration to make the atoms of adjacent host sheets vibrate, so that the composite current collector and the switching body are welded together.
