Talga secures strategic supply of recycled graphite feedstock from Aurubis for Talnode[®] -R anode

Battery materials and technology company Talga Group Ltd (“ Talga ” or “ the Company ”) is pleased to announce it has signed a non-binding Supply Agreement (“Agreement”) with Aurubis AG (“Aurubis”), a leading global provider of non-ferrous metals and one of the largest copper recyclers worldwide.

This Agreement enables Talga to secure high quality recycled graphite from lithium-ion battery production scrap, supporting manufacture of its Talnode[®] -R active anode product. Tailored for large scale applications in stationary energy storage and electric vehicles (EVs), Talnode[®] -R anode delivers high performance with minimal environmental footprint. In addition, by incorporating recycled feedstocks, Talga’s product stabilises supply chains, boosts circular economy, expands potential production sites and aligns with growing sustainability standards in the global battery materials market.

Under the terms of the Agreement, subject to definitive agreements, Aurubis intends to commence deliveries of recycled graphite from battery foils to Talga in 2028, with volumes scaling to an indicative maximum of 10,000 tonnes per annum by 2030. This initial agreement covers a period of up to three years from 2030 and the parties can agree to terminate or negotiate further extensions during this time.

This Agreement builds on the Development Agreement struck between Talga and Aurubis in September 2024 (ASX:TLG 10/9/2024) in which Talga’s pilot program successfully produced battery-grade anode material from recycled black mass from battery and production scrap. Using the Aurubis feedstock, Talga’s R&D team achieved product purity of 99.95%C, surpassing industry performance benchmarks and validating the technology’s scalability.

Talga Group CEO, Martin Phillips, commented : “Talga’s partnership with Aurubis continues to close the loop on battery supply chain waste. The sustainably produced graphite anode material is of high performance, and securing a reliable, eco-friendly feedstock source is not only an important step in commercialising Talnode[®] -R but also amplifies Talga’s technological moat.”

Aurubis COO Multimetal Recycling, Inge Hofkens, commented : “We highly value our partnership with Talga in developing a circular solution to recover copper and graphite from battery foils. This collaboration underscores Aurubis’ efforts towards innovation and sustainability in the industry and adds graphite as an additional value stream to Aurubis’ portfolio.”

Talga’s team is gearing up expanded production campaigns to generate more Talnode[®] -R anode for customer qualifications, enabling potential commercialisation in multiple markets. This development underscores the Company’s growth trajectory from single mine-to-anode project developer to global battery materials technology and production group.
