Ultrasonic welding for lithium ion battery tabs
a protective sheet is arranged on the welding area of the superimposed tab foil, and the welding horn is pressed on the protective sheet .The protective film is made of copper or aluminum. thickness normally is 0.1mm.
For larger copper foil, Battery tab pack welding applications, Bonne has developed the 4kW servo spot welder BN-X2040. This kind of high-power spot welding equipment can directly move the welding head, thereby improving the control ability and efficiency.
1.Innovative design allows operation in narrow areas, such as between battery lugs
