Altilium

Altilium is a Plymouth-based clean technology company founded in 2020 by Kamran Mahdavi and Dr Christian Marston, specialising in the recycling of end-of-life electric vehicle batteries and gigafactory manufacturing scrap into battery-grade materials. The company operates the UK's only functioning EV battery recycling facility at pilot scale and is developing what is planned to be the country's largest commercial-scale battery recycling plant, to be located in Teesside.

The company's proprietary EcoCathode hydrometallurgical process recovers over 95% of key battery metals from end-of-life cells, transforming them back into battery-grade cathode active materials (CAM) and metal sulphates ready for direct reuse in new batteries — with 74% lower CO₂ emissions compared to conventional mining. The planned Teesside facility will process battery waste from 150,000 EVs annually. Altilium has raised over $43 million total including a $12 million Series A led by SQM Lithium Ventures and a £4 million strategic investment from Marubeni Corporation.
