What is a Pure Nickel Strip?
A pure nickel strip is a thin, flat metal strip made from nearly 99.6% or more pure nickel. These strips are used to interconnect individual battery cells in a pack, especially during spot welding or resistance welding processes. The high nickel content offers excellent electrical conductivity and stability under high current loads.

Why is Pure Nickel Important for Battery Welding?
Not all nickel strips are created equal. Some cheaper alternatives use nickel-plated steel, which may look like pure nickel but offers inferior performance and increases the risk of overheating or corrosion.

Using pure nickel strips ensures:

Low resistance connections for efficient current flow.

High melting point, ideal for welding without damaging cells.

Excellent corrosion resistance, especially in humid or chemically exposed environments.

Longer battery life, due to better performance under load.

How to Identify Pure Nickel Strips
In the market, many suppliers offer nickel-plated steel strips instead of pure nickel to reduce cost. These look similar but perform very differently. Here’s how to tell them apart:

Spark Test: Steel produces sparks when ground; pure nickel doesn’t.

Magnet Test: Steel is magnetic; pure nickel has very low or no magnetic response.

Weight & Flexibility: Pure nickel is heavier and more pliable.

Corrosion Test: Dip both strips in saltwater—plated steel rusts; pure nickel won’t.
