When we think about the components that drive battery performance, foils often go under the radar, but they’re doing some of the heaviest lifting inside every cell. At Avocet, we understand the critical role that battery foils play in powering today’s most advanced battery technologies, and we’re proud to supply high-quality solutions trusted across multiple industries.
What Are Battery Foils?
Battery foils are ultra-thin layers of metal, typically copper and aluminium, that act as the current collectors for the anode and cathode in lithium-ion cells. They must be lightweight, highly conductive, mechanically stable, and compatible with ever-evolving electrode materials.
At Avocet Battery Materials, we supply copper, aluminium, nickel, lithium, and stainless-steel battery foils tailored for use in a wide range of cell formats and applications. Whether your cells are destined for electric vehicles, energy storage systems, or next-generation consumer electronics, the performance of your foils matters more than ever.
Why Quality Matters
Even the best electrode formulations can’t perform at their peak without the right foil. Poor foil quality can lead to uneven coating, poor conductivity, and reduced battery life. That’s why we focus on:
- Dimensional precision – Consistent thickness and surface quality
- Purity – High-purity copper and aluminium for optimal conductivity
- Adhesion – Clean foils with customised surface roughness & tensile strength for excellent compatibility with electrode slurry
- Scalability – Low MOQ’s suited for both R&D & mass production environments, served through our JV partnerships (AEF)
A Strategic Supply Chain
We work with globally recognised foil producers to offer our customers a stable, transparent supply chain, backed by technical support, application insight, and short lead times from our UK base.
Whether you’re refining a prototype or scaling for mass production, our battery foils are designed to meet your performance targets and manufacturing needs.
