Asking a low level question, why do we use nickel foil to solder lithium batteries?

1. Nickel sheets are inexpensive and can have irregular and diverse shapes.

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.

Nickel foils are easy to solder, have high tin absorption, and are more economical and affordable than copper foils. Additionally, copper has a drawback: it oxidizes easily in air and when the battery is damaged. opened, a green patina will appear --- the DeVos lithium battery reminds you!
