Key Benefits
Superior Weldability
Nickel surface ensures consistent, reliable ultrasonic welding with >99.5% yield rate.
Low Contact Resistance
Copper core provides high conductivity, reducing internal resistance and heat generation.
Corrosion Resistance
Nickel cladding resists electrolyte corrosion for long-term cell stability.
Cost Advantage
NCC replaces pure nickel at 30% lower cost while maintaining performance.
Applications
Cylindrical Cells (18650, 21700)
NCC tabs for high-volume cylindrical cell production with proven reliability.
Prismatic Cells
Wider NCC strips for prismatic cell terminals with excellent flatness.
Pouch Cells
Thin NCC foils for pouch cell tabs with precise thickness control.
Frequently Asked Questions
Why use NCC instead of pure nickel for battery tabs?
NCC provides 85-95% IACS conductivity vs 25% for pure nickel, reducing internal resistance. The nickel surface maintains weldability while the copper core improves electrical performance at 30% lower cost.
What cladding ratio should I choose?
10/80/10 is standard for most applications. 15/70/15 provides more nickel for harsher environments. 20/80 (single-sided) is used for specific welding requirements.
