Why do we choose ultrasonic welding machine for lithium battery ear welding?

Advantages of ultrasonic welding machine:

1) Ultrasonic nickel-metal hydride battery electrode sheet welding machine welding material is not molten, not fragile metal characteristics.

2) Lithium battery pole ear welding machine has good conductivity after welding, and the resistance coefficient is very low or almost zero.

3) Nickel-metal hydride battery pole ear welding equipment has low requirements on the welding metal surface, and can be welded by oxidation or electroplating.

4) Multi-layer aluminum foil welding equipment welding time is short, does not need any flux, gas, solder.

5) Lithium battery positive electrode welding equipment welding without spark, environmental protection and safety.

Ultrasonic welding of battery pole ear is mainly divided into single point and multi-point welding, another important use for automatic pole welding machine and automatic winding machine matching ultrasonic welding. Used for welding single layer copper and aluminum foil with nickel sheet or copper sheet and aluminum sheet of positive and negative electrode ears of lithium ion battery. The copper foil is about 0.08mm, the aluminum foil is about 0.01mm, and the nickel and aluminum sheet is about 0.1mm. Battery field has lithium battery, power battery, polymer battery, battery positive electrode, battery negative electrode, battery ear and so on.

Ultrasonic battery metal spot welder is especially suitable for:

Nickel strip copper foil, nickel strip aluminum strip, aluminum strip aluminum foil, aluminum strip aluminum cover, aluminum shell aluminum nickel composite strip and other materials of single point, multi-point, single layer, multi-layer, square, strip, monolithic and other processes of welding.
