At Avocet Precision Metals, we supply ED copper foil that meets the needs of cutting-edge battery manufacturers. Whether you’re in R&D, pilot line testing, or full-scale gigafactory production, our copper foil delivers the consistency and mechanical performance your process demands.

Why ED Copper Foil?

ED (electrodeposited) copper foil is created through an electrochemical process that produces a highly uniform, fine-grain copper sheet. Its role in a battery cell is deceptively simple: act as the current collector. But how well it performs in that role can impact everything from charge rate and thermal stability to manufacturing yield.

That’s why our foil is engineered for:

High tensile strength to withstand coating and calendering

Excellent elongation to prevent tearing during winding

Low surface roughness for better adhesion and uniform current flow

Thermal stability – even at temperatures up to 180°C

Simply put, it’s built to survive the production line and perform inside the cell.

Built for High-Speed Battery Manufacturing

Our customers operate in fast-moving, highly competitive markets, and our foil is designed to keep up.

It offers:

Uniform mechanical and surface properties across the roll

Available in wide formats (up to 1300mm) for maximum throughput

Short lead times, helping you meet launch schedules or scale quickly

Packaging built for protection: robust wooden crates with suspended coil ID

Whether you’re coating anodes for a next-gen EV platform or prototyping solid-state designs, we tailor coil sizes to your exact needs, no off-the-shelf compromise.

Who Is This For?

We supply ED copper foil to:

EV and battery pack manufacturers

Cell developers focused on pouch and cylindrical formats

Energy storage (ESS) integrators

Power tool and industrial battery makers

Research labs and pilot lines working on next-gen chemistries

If your business depends on batteries, we can help you build them better.
