A three-in-one strategy for lithium recovery and upcycling of spent cathode materials.

ABSTRACT: The recycling of spent lithium-ion batteries is essential for sustainable development of clean energy industry. Traditional recycling methods face challenges such as high energy/chemical consumption and limited adaptability. This study introduces a 'Three-in-One' strategy that leverages mechanochemical (MC) treatment to enhance lithium recovery, transition metal upgrading, and CO₂ sequestration. MC treatment induces micro-segregation of lithium and transition metals, resulting in a structurally disordered material with a Li-rich surface, facilitating selective lithium extraction. Subsequently, CO₂ is used as the sole reagent and lithium leaching efficiency exceeding 95% is achieved by forming lithium bicarbonate. Conducted under ambient conditions without additional g
