Most lithium battery combinations are produced and processed using nickel foil and spot welding technology. This method is the most successful and least expensive production method.
The reasons analyzed by PACKWANG are as follows:
1. Nickel sheets are inexpensive and the shapes can be irregularly diversified.
2. Spot welding technology is mature, and the spot welding machines on the market are also very cheap.
3. Spot welding of combined lithium batteries can basically ignore production tools and save a lot of costs.
4. Maintenance and disassembly after welding are also more convenient. Some disassembled batteries only need to polish the cell welding surface for reuse.
I hope the above answer from packwang can help you.
