In advanced energy systems, material performance matters. Whether you’re developing lithium-ion batteries, fuel cells, or next-generation capacitors, the quality and consistency of the battery grade copper foil you use directly impacts reliability, safety, and efficiency.
At Avocet Electrofoils, we specialise in supplying high-quality electrodeposited copper foil that meets the strict requirements of today’s energy storage and conversion technologies. Our material is already in mass production, approved by leading battery and electronics manufacturers around the world.
What Makes Copper Foil ‘Battery Grade’?
Battery grade copper foil is not just a thinner version of standard foil. It must be engineered with:
- Precise thickness uniformity (typically 6–12 µm)
- High purity to reduce internal resistance and avoid contamination
- Controlled surface profile to ensure adhesion and stability
- Mechanical durability for coating, slitting, and roll-to-roll processes
These characteristics make it suitable not just for lithium-ion anodes, but also for high-performance applications across industries including electric mobility, grid storage, aerospace, and defence.
Designed for Scale and Reliability
We support both prototype projects and full-scale production, offering:
- Mass production availability with a capacity of 20KT (targeting 40KT by 2031)
- UK-based distribution and support via Avocet Electrofoils
- Full technical documentation and traceability
- Future European production via our joint venture, European Electrofoils
Whether you’re facing performance issues, planning to scale up, or simply looking for a more dependable supplier, our battery grade copper foil is built to meet your needs.
