Aqua Metals uses bench-scale testing to recycle LFP

Bench-scale testing and engineering analysis for Aqua Metals’ new process for recycling lithium-ion phosphate (LFP) battery materials are now complete. This process emphasises the company’s position as a leader in the movement towards a circular battery supply chain and highlights Aqua Metals’ technology’s adaptability to market needs.

It is possible to add the LFP recycling process into the scheduled Sierra ARC facility, as well as any ARC facility that has an incremental capital expense of 25% to 30% and adding the process to this facility and/or any ARC facility can be completed, without needing to expand the facility’s physical footprint. This was proven by the company’s engineering and techno economic analysis. Whilst the Sierra ARC is designed to process 7,500 tonnes of NMC-type black mass every year, an extra 7,500 tonnes of LFP feedstock could be processed as well, by adding LFP capabilities. This would double the facility’s lithium carbonate output to 2,700 tonnes annually. Once operational this facility will make Aqua Metals one of the largest producers of domestic battery-grade lithium carbonate, as the change the company is bringing to the market, will increase the total U.S. lithium production to over 50% every year.

This development means Aqua Metals is actively aiming to meet the increasing requirement for LFP recycling while also working to keep lithium within the domestic supply chain. The company is also involved in supporting U.S. leadership in clean energy and advanced manufacturing.

Steve Cotton, President and CEO of Aqua Metals, commented “We believe this is an important step in our strategy to develop the most adaptable and scalable lithium battery recycling platform in the industry. Our ability to integrate LFP recovery into our existing plans demonstrates how we can evolve with market needs while maintaining a focus on efficiency, sustainability, and long-term impact.”

Ben Taecker, Chief Engineering and Operating Officer at Aqua Metals, mentioned “Recycling LFP batteries has posed a major technical hurdle for the industry due to its unique chemistry and limited market value. This milestone demonstrates how adaptable our technology platform is — and positions Aqua Metals at the forefront of building the next generation of clean, scalable recycling solutions for the evolving battery landscape in North America.”
