Altilium: Recycled EV Batteries Outperform Virgin Materials

Welcome, Net Zero News readers,

In an era where the transition to sustainable energy is more crucial than ever, new research has emerged that shines a promising light on the potential of recycled materials in electric vehicle (EV) batteries. A recent study conducted by the esteemed Imperial College London in collaboration with the UK clean technology firm Altilium has revealed groundbreaking findings: recycled cathode active materials (CAM) can not only match but also outshine the performance of their virgin-mined counterparts.

This research is a significant step forward in the quest for sustainable battery solutions, highlighting the benefits of using recycled materials in enhancing battery performance. The study showcases improvements in purity, morphology, and electrochemical performance of recycled CAM when compared to commercially available materials. These advancements could lead to a new era of batteries that last longer, charge faster, and come at a reduced cost.

Under the auspices of this research programme, Imperial College conducted thorough electrochemical testing on both coin cells and pouch cells that were manufactured using recycled CAM generated at Altilium’s ACT1 facility located in Devon. The results were nothing short of remarkable, demonstrating superior rate and cycle performance compared to the commercially available CAM typically used in high-nickel NMC 811 batteries.

Altilium’s recycled CAM materials boasted a cycle cell capacity exceeding 150 mAh.g−1, significantly surpassing the standard ranges seen in mined materials. Furthermore, the analysis of these recycled CAM samples revealed noteworthy advancements in particle size and distribution, which directly contributes to enhanced stability and cycling behaviour. This is a vital component in the development of reliable battery technologies.

One of the most compelling aspects of the study is the observation of minor changes during testing, which affirmed the chemical and physical robustness of the recycled CAM. This robustness is crucial for ensuring long-term battery performance, making these materials an exciting prospect for manufacturers and consumers alike.

The findings from this research underscore the immense potential of Altilium’s proprietary EcoCathode™ process, a pioneering method capable of recovering over 95% of critical metals—including lithium—from end-of-life EV batteries. This innovative approach not only addresses the pressing issue of battery waste but also contributes to the circular economy by repurposing materials that would otherwise be discarded.

Dr Christian Marston, Altilium’s co-founder and COO, expressed his enthusiasm for the research outcomes, stating, “These results confirm the reliability and superior performance of Altilium’s materials and validate our mission to build a UK champion for EV battery recycling. Recycled CAM not only aligns with global sustainability goals but also offers improved technical performance at a lower cost, making it a game-changer for the EV industry.”

As we delve deeper into the implications of these findings, it becomes evident that the integration of recycled materials into the EV battery supply chain could significantly reshape the industry landscape. The potential for reduced costs and enhanced performance may not only benefit manufacturers but could also translate to better affordability for consumers, thereby accelerating the adoption of electric vehicles.

The urgency of transitioning to sustainable practices is underscored by the increasing demand for EVs. As governments around the world set ambitious targets for reducing carbon emissions, the need for innovative solutions that minimise environmental impact becomes ever more pressing. The utilisation of recycled materials in battery production presents a viable pathway toward achieving these goals.

Moreover, the benefits of recycling extend beyond just improved battery performance. The process of recycling EV batteries can significantly reduce the need for virgin mining, which is often associated with environmental degradation, habitat destruction, and substantial carbon emissions. By investing in recycling technologies like Altilium’s EcoCathode™, the industry can work towards minimising its ecological footprint while meeting the growing demand for battery materials.

As we look ahead, the advancements in battery technology and recycling processes are set to play a pivotal role in not only the EV sector but also in the broader context of renewable energy. The shift towards a circular economy is not merely a trend; it is a necessity for sustainable development. The findings from Imperial College and Altilium exemplify the innovation and commitment required to turn this vision into reality.

In conclusion, the research conducted by Imperial College London highlights a significant leap forward in the realm of battery technology. The ability of recycled CAM to outperform virgin materials opens the door to a more sustainable and economically viable future for the EV industry. As we continue to champion the cause of net zero emissions, the integration of innovative recycling processes will undoubtedly play a critical role in shaping a cleaner, greener world.

Let us continue to support and promote initiatives that prioritise sustainability and innovation in all sectors, particularly in the fast-evolving electric vehicle landscape. Together, we can champion the future of net zero and create a lasting impact for generations to come.
