8th April, 2026 – Altilium, a UK-based clean technology group focused on sustainable recovery of critical battery minerals, has today announced the filing of its 10th UK patent application, covering its proprietary process for production of key battery intermediates, including nickel MHP (mixed hydroxide precipitate), from recycled feedstocks.

This latest patent application marks a significant addition to the company’s intellectual property portfolio and follows a key technical milestone in the advancement of Altilium’s green processing technologies, with the commercial production of nickel MHP for customer qualification at its ACT2 pilot plant, demonstrating the commercial readiness of the process and its ability to meet stringent industry specifications.

Developed at the company’s ACT2 facility, the new MHP flowsheet enables the recovery of critical battery materials from a wide range of feedstocks such as end-of-life lithium-ion batteries, black mass and manufacturing scrap. The process is designed to produce high-quality, low carbon MHP, containing both nickel and cobalt, alongside lithium sulphate. These recovered materials can then be directly reintegrated into new battery production, enabling a truly circular UK battery supply chain.

Altilium will deploy the proprietary process at its new ACT3 commercial facility, currently under construction in Plymouth, which will produce approximately 3,200 tonnes per annum of nickel MHP once commissioned. This scale-up represents a significant step toward establishing a domestic, sustainable supply of battery-grade materials in the UK.

MHP is increasingly the preferred feedstock for producing battery-grade nickel sulphate for use in EV batteries. Currently Indonesia is by far the largest global supplier of MHP, with market share projected to reach over 80% by 2030. Establishing a domestic supply chain is critical for the UK’s energy security and geopolitical resilience, supporting the development of a globally competitive battery industry and the transition to net zero.

Christian Marston, Altilium COO, commented: “This patent filing reflects the strength of our technology platform and our continued focus on innovation in battery recycling. By converting recycled materials into high-value intermediates like nickel MHP, we are helping to close the loop on battery production, reduce reliance on primary mining and onshore production of EV battery materials.”

The new patent application forms a key part of Altilium’s growing suite of UK-based intellectual property, which also spans graphite recycling for anode materials, black mass processing into pCAM and CAM and advanced blending techniques to meet EU minimum recycled content requirements.

Together, these innovations establish a strong economic and technological moat, positioning Altilium as a leading force in building a domestic, circular battery ecosystem and a national recycling champion.

About Altilium
Altilium is a UK-based clean tech group that is reshaping the UK and European automotive supply chain by offering high volume, low carbon domestic sources of cathode and anode materials from recycling waste streams already in circulation, such as end-of-life batteries.

The company’s proprietary EcoCathode™ process converts end-of-life EV batteries and manufacturing scrap into domestic, sustainable, battery precursors, cathode active materials (CAM) and cathode precursor (pCAM) for direct reuse in new batteries.

Altilium’s first pilot plant commenced operations in Plymouth in 2025 while its planned Teesside plant will be one of the largest EV battery recycling facilities in Europe. The plant will have the capacity to process scrap from over 150,000 EVs per year, producing 30,000 MT of CAM, enough to meet around 20% of the UK’s expected needs by 2030.

The company is backed by SQM Lithium Ventures, the corporate venture arm of the lithium business of Sociedad Quimica y Minera de Chile (SQM), Japanese trading and investment group Marubeni Corporation and Mizuho Bank.
