ReLiB scientists at the University of Birmingham have developed and patented a phase selective leaching technology to recycle, upcycle and regenerate cathode materials.

The process successfully separates manganese-rich phases from mixed/blended cathode materials – the most valuable component of battery systems. These phases can be regenerated or, due to the adaptability of the process, can be upcycled to next generation cathode materials. By combining this with a direct recycling approach, the remaining high value Ni- and Co-rich phases can also be recovered and regenerated, thus enhancing the UK’s capability in recycling and positioning the UK well as the world transitions to zero emission vehicles.
