1. The aluminum-clad nickel strips are first welded on the aluminum row, and the pure nickel strip is welded.

2. The two materials are combined into one. The welding material is made of aluminum-nickel strip on one side and nickel on one side. This requires only one weld on the aluminum plate.

3. Directly on the aluminum row of composite strips or all nickel strips (0.15 ~ 0.25 thick) by machining or corrosion method, remove the aluminum on the nickel and then stamp.

★★ In addition, aluminum can be replaced with copper according to customer's special requirements for better performance. ★★

1. Lightweight design, through 7000 pieces of 18650 combination, the connection row weight is reduced by 8KG.

2. Good spot welding effect, lower internal resistance, longer discharge time of battery pack and firmer spot welding of battery

3. Because of the good weldability of nickel, it is directly welded to copper and improves welding reliability.

4. The industry has matured and the product has undergone 3 generations of evolution.

5. High product stability.

6. The cost is reduced by half, and 1000-2000 yuan is saved for each vehicle.
