Direct Cathode Recycling of Li-Ion Batteries from Electric Vehicles

Direct cathode recycling presents a sustainable, energy-efficient solution for recovering end-of-life lithium-ion electric vehicle (EV) batteries by maintaining the structural integrity of cathode materials. While environmentally advantageous, the process continues to face challenges related to achieving consistent material purity. This study introduces a novel separation technique that addresses these limitations, enabling cost-competitive, scalable production of high-purity cathodes with structural, compositional, and electrochemical properties comparable to those of commercially manufactured counterparts.
