Alex Green is part of the ReLiB project, with his research focusing on developing novel niobate materials and exploring innovative methods for recycling high-power anodes in energy storage systems. He has devised a unique approach to upcycle lithium titanate oxide (LTO) anodes, commonly used in high-power lithium-ion batteries, into next-generation niobate anode materials. This upcycling process not only enhances the electrochemical performance, but hopes to contribute positively to worldwide sustainability in recycling.
Currently, I am investigating strategies to directly recycle niobate anodes, exploring their reusability and recovery potential without compromising their structural integrity or performance. By addressing both the development of advanced materials and the efficient recycling of high-performance anodes, my work aims to reduce the environmental impact of battery production while advancing the capabilities of next-generation energy storage technologies for applications such as mining and rail transport.
Recycling lithium-ion batteries, particularly those with high-power anodes like niobates and titanates, offers significant environmental, economic, and technological benefits. Environmentally, it reduces the extraction of critical raw materials, such as lithium and niobium, and prevents hazardous waste from polluting ecosystems. Economically, recycling reduces reliance on mining and lowers production costs by recovering valuable materials for reuse.
Technologically, effective recycling supports the development of next-generation batteries by ensuring a steady supply of high-performance materials, enhancing battery life cycles, and improving energy density. Overall, recycling these high-power anode materials fosters a more sustainable and circular economy, which is essential for the widespread adoption of clean energy.
The highlight of my research so far has been the opportunity to work within a highly collaborative team as part of the ReLiB (Recycling of Lithium-Ion Batteries) project. This experience has allowed me to engage with leading experts and contribute to cutting-edge developments in battery recycling and materials science. I have published three papers based on my work, showcasing the novel approaches we’ve developed, and had the privilege of presenting at multiple national and international conferences. A standout moment was presenting my research at the 64th Battery Symposium in Osaka, Japan, where I had the chance to share my work with a global audience of researchers and industry leaders. These experiences have been invaluable in advancing my research and expanding my professional network within the field.
