4680 Cell Nickel Strip Busbar Manufacturer and Exporter

Name: 4680 Cell Nickel Strip Busbar
Brand: Aurico Alloys LLP
Availability: InStock

Aurico Alloys LLP manufactures pure nickel strip busbars for 4680 cells - the 46 mm by 80 mm cylindrical format used in current-generation electric vehicle packs.

The 4680 format concentrates far more current into each interconnect than 18650 or 21700 designs, so busbar cross-section, weld area and thermal path all have to be sized deliberately rather than carried over from a smaller-format pack.

Why Pure Nickel

Pure nickel spot-welds consistently to steel cell cans, resists electrolyte and humidity inside the pack, and holds a stable low contact resistance across thousands of cycles. Plated steel loses that stability as the plating wears through, and bare copper will not weld reliably to a cell can without a nickel interlayer.

Applications

Application	Typical use
Electric vehicles	Structural battery packs built on 4680 cells.
Energy storage	High-capacity stationary storage modules.
Commercial vehicles	Bus, truck and off-highway traction packs.
Prototyping	Development packs and test fixtures.

Frequently Asked Questions

A 46 mm diameter, 80 mm tall cylindrical lithium cell. The larger format cuts the number of interconnects in a pack but pushes far more current through each one, so busbar cross-section matters more than it does on 18650 or 21700 builds.

Heavier than typical 18650 work because of the higher per-cell current. Send us your continuous and peak current and pack layout and we will propose a cross-section and weld schedule.

Commercially pure nickel to 99.6% minimum, ASTM B162 Nickel 200/201.

Yes. Send a DXF or STEP file and we will laser cut to your cell pitch, including fused-link designs.

Yes. Nickel-copper sandwich busbars keep a weldable nickel surface over a copper core where pure nickel cannot carry the current economically.
