|a The efficient recovery of lithium in spent lithium-ion batteries (LIBs) is of key significance to alleviate the resource utilization of lithium in solid waste. Herein, a ethylene glycol (EG) assisted subcritical method is proposed for the selective recovery of lithium. Under the optimal conditions with reaction temperature of 270℃, reaction time of 3 h, rotational speed of 300 r min-1, L/S ratio of 10:1 mL g-1, and EG dosage of 60 %, lithium can be leached with efficiencies of up to 98.4 % while the transition metals remain in the residue phase as oxides (NiO and CoO) or carbonate (MnCO3). The subcritical lithium extraction mechanism indicates that the hydroxyl functional group of EG and the pyrolysis gas played a synergistic role in reducing the cathode powder. The EG-assisted subcritical lithium extraction system greatly improves the recovery efficiency of lithium under more environmentally friendly conditions, and lays a good foundation for the subsequent low-acid leaching of lithium extraction residue. This process provides a novel approach to the green and selective recycling process of spent LIBs
