As the global shift to electrification accelerates, every layer of a lithium-ion cell plays a critical role in performance, efficiency, and safety. One of the most overlooked, but absolutely essential components? Lithium battery copper foil.
At Avocet Electrofoils (AEF), we specialise in supplying high-quality electrodeposited copper foil designed specifically for lithium-ion anodes. With decades of expertise and a strong distribution network across the UK, Europe, and the US, our copper foil is already approved by some of the world’s top battery manufacturers.
What Is Lithium Battery Copper Foil?
Lithium battery copper foil is a thin, highly conductive layer used as the anode current collector in lithium-ion cells. Its job is to carry electrons efficiently, but it must also be manufactured to extremely tight tolerances to avoid structural or chemical issues that could degrade battery performance.
Our copper foil is produced in partnership with Yihao New Materials Co and tailored for use in everything from electric vehicles to grid-scale storage. It’s engineered for reliability, performance, and mass production—with a current capacity of 20KT and expansion plans to 40KT by 2031.
Bridging Today’s Market with Tomorrow’s Supply Chain
At AEF, we’re not just distributing copper foil—we’re building the future of battery materials in Europe. As part of a joint venture with Yihao New Materials Co and Tex Technology Inc, we’re working to establish a copper foil manufacturing facility in Europe by 2028.
Until then, AEF continues to deliver lithium battery copper foil with full traceability, fast lead times, and technical support from our UK-based team.
