Altilium, a UK-based clean technology group focused on supporting the transition to net zero, and Connected Energy, a developer of second-life battery energy storage systems, announced a new strategic relationship that will see the two companies working together to extend the lifecycle of EV batteries.

Connected Energy designs and develops energy storage systems using second life EV batteries, while Altilium is a pioneer in EV battery recycling, processing end-of-life EV batteries and manufacturing scrap to produce low-carbon cathode active materials (CAM) for direct reuse in new batteries.

Under the agreement, Altilium and Connected Energy will collaborate to develop sustainable and environmentally responsible business models for the repurposing and recycling of EV batteries, bringing value to both companies as well as battery manufacturers and automotive OEMS.

The collaboration also aims to establish responsible repurposing and recycling protocols, to be adopted as industry wide standards, following the waste hierarchy principles of re-use, re-purpose and recycle.

Repurposing EV batteries in stationary systems can extend their life by up to ten years, delivering significant environmental and circular economy benefits. Once these batteries reach the end of their second life, they can then be recycled and the critical minerals recovered for reuse in the production of new batteries, ensuring that valuable resources remain in the UK supply chain.

Altilium has already received its first batch of batteries from Connected Energy, which will be processed at the company’s recycling facilities in Devon. Using its EcoCathode recycling process, Altilium can recover more than 95% of the battery metals, including lithium, in a format that can be directly reused in the production of new batteries.

The process also results in a 60% reduction in carbon emissions and 20% lower costs compared to virgin materials, paving the way for the production of more affordable and even cleaner EVs.

Connected Energy’s storage systems are increasingly used across the UK and Europe for applications such as supporting EV charging hubs, cutting energy bills, balancing the grid, and maximising the return on investment from solar arrays. Giving their batteries a second life enables EV manufacturers and other battery owners to further monetise their batteries for several years before they are recycled.

Through this collaboration, Connected Energy hopes to capture more of the residual value of these spent batteries once they reach the end of their second life, while Altilium will gain more visibility of available feedstock for its recycling facilities, including its planned Teesside refinery (ACT 4). The plant will have the capacity to recycle waste batteries from 150,000 EVs a year, producing 30,000 MT of CAM, enough to meet 20% of the expected UK demand by 2030.

Both companies are already part of a £30.1-million Nissan-led project, backed by the Advanced Propulsion Centre, aimed at strengthening the UK’s capabilities in EV battery reuse, recycling and grid balancing.
