Nickel Strip

High-purity nickel strip is widely used as a low-resistance current-carrying connector (“tab” or “bus strip”) in battery cell assembly. In lithium-ion, sodium-ion and nickel-based cells, nickel strip provides a reliable electrical pathway between electrodes, tabs and external terminals, and is commonly joined using spot welding (resistance welding). Nickel’s combination of electrical conductivity, mechanical robustness, and corrosion resistance helps maintain stable interconnect performance during cycling and storage.

Key Specifications (Typical)

• Purity: >99.9% Ni
• Width options (mm): 5, 6, 8, 10, 12, 15, 20 (custom widths available)
• Thickness options (mm): 0.10, 0.15, 0.20, 0.30
• Form factor: Supplied as strip/coil for convenient cutting and welding
  
  

Why Nickel Strip Matters in Cell Assembly

• Excellent spot-weldability: Supports consistent weld nugget formation for repeatable connections
• Low contact resistance: Helps minimise I²R losses and localised heating at joints
• Corrosion resistance: Suitable for demanding lab and pilot-scale environments
• Process compatibility: Integrates with tab welders, strip cutters, and cell assembly workflows
  
  

Typical Applications

• Cylindrical cell (e.g., 18650/21700) pack prototyping and module interconnects
• Pouch cell tab joining and laboratory current lead fabrication
• Nickel-based chemistries (NiMH/NiCd) and general electrochemical hardware builds
