| Summary: | The recycling of Lithium-Ion Batteries (LIBs) holds promise for addressing the scarcity of lithium resources and the environmental impacts of their extraction. This study investigates reusing recovered Li2CO3 in a direct LIB recycling. Li2CO3 recovery is achieved through reduction roasting and water leaching. Two distinct methods, heat and solvent debinding, are used for separation of spent cathode powders and employing them in a solid-state reconstruction reaction, using both laboratory-grade and recovered Li2CO3, to reconstruct cathode structures. Under optimized conditions, Li2CO3 recovery efficiency reaches 92.6 wt%. The solid-state reconstruction reaction at 850°C and 900℃ for the cathode separated by heating and dimethylformamide solvent debinding, respectively, alongside laboratory-grade Li2CO3, lead to successful cathode structure reconstruction and direct recycling. Notably, the samples reconstructed with recovered Li₂CO₃ retained over 93.44% of the capacity compared to those using laboratory-grade Li₂CO₃. These findings validate the competency of recovered Li2CO3 in cathode structure reconstruction and direct LIB recycling. |
