Pure Nickel Strip 0.15mm x 8mm for 18650 Battery Welding (Per Meter)

Product Overview and Material Composition

Engineered specifically for high-reliability lithium-ion battery pack assembly, this 99.96% pure nickel strip delivers ultra-low electrical resistance and exceptional conductivity. Unlike nickel-plated steel alternatives, pure nickel prevents rust, reduces internal resistance, and guarantees maximum current throughput. Measuring 0.15mm in thickness and 8mm in width, this ribbon is optimized for joining 18650, 21700, and 26650 cylindrical cells into custom series and parallel configurations without adding unnecessary mass or bulk.

Thermal and Electrical Performance

Designed to handle continuous discharge loads of up to 5 to 7 Amperes per strand, this pure nickel strip exhibits superior thermal dissipation under high ampacity draws. The 0.15mm thickness offers the ideal balance between mechanical tensile strength and low electrical resistance, preventing localized heating across series interconnects. Its high-purity metallurgical composition prevents oxidation over extended operational cycles, keeping contact resistance low across multi-cell energy storage arrays.

Spot Welding and Assembly Integration

This nickel strip is tailored for capacitive discharge and pulse spot welding systems. The precise 0.15mm cross-section melts consistently under standard welder power settings without burning through cell end-caps or damaging delicate internal PTC insulators. The strip can also be easily tinned and soldered with minimal thermal input if supplemental lead connections or balance wires are required. Sold by the meter, it allows custom cutting to form busbars, series bridges, and custom cross-over grids for compact or large-scale pack topologies.

Broad Application Versatility

This low-impedance nickel ribbon is widely used across professional and hobbyist energy projects. Primary applications include custom electric vehicle (EV) battery modules, electric bicycle and scooter power packs, cordless power tool rebuilds, high-drain RC battery arrays, off-grid solar energy storage walls, and uninterruptible power supply (UPS) backups.
