About Avocet Electrofoils (AEF)
Building the copper supply chain
We focus on supporting the current and emerging PCB and battery industries in Europe. Our foil has been approved by some of the world’s best manufacturers, and is already in mass production with a mill capacity today of 20KT and expansion plans to reach 40KT by 2031.
AEF sales and distribution operate from the UK facility in Cheshire and serve the European and US markets with copper foil manufactured by Yihao New Materials Co. AEF was created to support the joint venture company set up between Avocet Materials Group, Yihao New Materials Co Ltd, and Textechnolgy Inc. The Joint Venture company aims to establish a copper foil manufacturing facility in Europe by 2030.
AEF is owned and operated by Avocet Materials Group, a collection of complimentary companies that are in the manufacturing sector specifically focused on battery materials. At the heart of our philosophy we understand the needs of manufacturers and work with them to tackle the significant challenges they face.
The Pathway to European Production
In July 2023, Avocet Materials Group signed a Memorandum of Understanding with Yihao New Materials Co Ltd and Tex Technology to establish a European manufacturing site for Copper Foil production.
In March 2024, the 3 companies agreed to form a Joint Venture company (European Electrofoils) to manufacture battery copper foil in Europe. The project is now in site selection phase.
AEF will supply foils from Yihao New Materials Co prior to establishing the European site (expected 2030).
