Lithium-ion battery electrode ear ultrasonic welding machine is mainly divided into single-point welding and multi-point welding. Another important application is ultrasonic welding for automatic electrode welding machine and automatic winding machine. For welding single-layer copper foil, aluminum foil and nickel sheet or copper foil, aluminum foil, copper foil is about 0.08mm, aluminum foil is about 0.01mm, nickel and aluminum foil is about 0.1mm.

       1. 20K or 40K welding machine can be used for single-point welding, and 40K full-wave welding head is used for automatic winding machine.

       2. Determine the shape of the welded joint according to the battery electrode and material requirements.

       3. The design of the welding head and the estimated grain size of the bottom are very critical. Companies that don't do well will use wire-cut or electro-etching processes for die processing, with poor consistency defects.
