Faster, greener technique to improve recycling process for electric vehicle batteries

Researchers working on the Faraday Institution project on the recycling of lithium-ion batteries (ReLiB) at the Universities of Leicester and Birmingham have solved a critical challenge in the recovery of materials used in electric vehicle batteries at the end of their life, enabling their re-use in the manufacture of new batteries. The new method, which uses ultrasonic waves to separate out valuable material from the electrodes, is 100 times quicker, greener and leads to a higher purity of recovered materials relative to current separation methods.
