  Aluminum Nickel Composite Strip for Battery Tab

  The Aluminum Nickel Composite Strip is a high-performance solution engineered for battery tab applications in lithium-ion battery assembly. Manufactured with an optimal 1:2 alloy ratio of high-purity aluminum (≥99.5%) and nickel (≥99.6%), this composite strip provides excellent conductivity, strong weldability, and mechanical durability.

  With a precisely controlled width of 4 mm and thickness of 0.1 mm (±0.0005 mm), this strip is ideal for laser and ultrasonic welding processes, ensuring consistent contact and secure sealing between internal cell components and external circuitry. The strip’s compatibility with aluminum casing parts makes it particularly valuable in the production of cylindrical and prismatic lithium-ion cells.

  Key Features:

  • Dual-metal composition ensures high electrical conductivity and oxidation resistance
