How big is the nickel strip for lithium battery pack

So, keep that in mind when shopping for nickel strips. The most commonly available pure nickel strips are 7mm wide, though 10mm is readily available. There are some 47mm strips, but there is a large air gap in the middle. If you need more current, you could always spot-weld 2 to 3 layers of nickel strips on top of each other for more capacity.

Nickel is the preferred conductor to connect lithium-ion battery cells together. Nickel strip is the most common material used in lithium-ion battery construction because it is easy to spot weld and has excellent anti-corrosive properties while having a relatively low cost. 99.6% pure nickel strip in a variety of lengths, widths, and thicknesses.

99.6% pure nickel strip in a variety of lengths, widths, and thicknesses. Perfect for spot welding directly to lithium ion cells. You can use copper in conjunction with nickel for increased amperage capacity. All you need to do is add a layer of copper underneath the nickel strip, commonly called a copper/nickel sandwich.

Most low-cost welders have a hard time around 0.15mm, and most cannot even work with 0.20mm, even on the highest settings. So, keep that in mind when shopping for nickel strips. The most commonly available pure nickel strips are 7mm wide, though 10mm is readily available. There are some 47mm strips, but there is a large air gap in the middle.

Perfect for use with nickel in increasing amperage capacity for your pack. Pure nickel is around twice as conductive as nickel-plated steel. Nickel-plated steel has its use cases, but nickel-plated steel should never be used for battery construction.

The real problem is the fact that many online vendors sell nickel-plated steel as pure nickel. When it comes to pure nickel strips, the thickness can vary from 0.1mm to 0.3mm. Most low-cost welders have a hard time around 0.15mm, and most cannot even work with 0.20mm, even on the highest settings.
