Frequently Asked Questions
N6 Nickel Strip FAQ For Battery And Industrial Applications
1. What Is N6 Nickel Strip?
N6 Nickel Strip is a high purity nickel strip made from nickel material with approximately 99.6% nickel content. It features excellent conductivity, softness and corrosion resistance.
2. Why Is N6 Nickel Strip Used For Battery Connection?
N6 nickel strip provides good electrical conductivity, excellent weldability and reliable mechanical flexibility, making it suitable for lithium battery connections and battery pack assembly.
3.What makes N6 soft-annealed nickel strip optimal for battery tab spot welding?
In the annealed soft state (temper M, 90–120 HB), N6 strip provides superior ductility (elongation ≥ 30%) and optimal electrical conductivity (~18% IACS). This prevents weld blowout on thin 18650/21700 cell bottoms, ensures clean nugget formation during resistance/ultrasonic welding, and prevents stress-cracking when folded inside battery modules.
