Battery Ultrasonic Spot Welder Machine For 18650 & Pouch Cell Al/Ni/Cu Metal Tab Foil Welding

At present, lithium-ion batteries have the advantages of high specific energy, more recycling times, and long storage time. They are not only widely used in portable electronic devices such as mobile phones, digital cameras, and laptops, but also widely used in electric vehicles, electric bicycles, and electric tools and other large and medium-sized electric equipment. Therefore, the performance requirements of lithium-ion batteries are increasingly high.

In the field of electric tools using lithium ion batteries, with the increasing requirements of customers, the capacity of the battery cell and the discharge current of the battery pack are gradually increasing, so the thickness of the nickel strip is also gradually increasing. The existing nickel strip includes a positive nickel strip 1, a negative nickel strip 2 and a nickel strip connection part 6. The positive nickel strip 1 and negative nickel strip 2 are respectively located at the left and right ends of the nickel strip connection part 6.

For the existing ultrasonic metal welding machine, in order to weld thick nickel strips (such as 0.3 mm thick nickel strips), it is necessary to increase the power during welding and use higher power for welding, which will greatly reduce the service life of the spot welding machine, and is prone to dangerous situations, causing the spot welding machine to burn out due to high power operation. Therefore, there is an urgent need to develop a nickel strip at present. While increasing the thickness, the spot welder does not need to increase the working power. The spot welder can complete welding under the normal use power.
