| Abstract Scope |
The growing demand for Li-ion batteries across industries has significantly increased electronic waste, highlighting the urgent need for sustainable recycling methods. LiFePO4 (LFP) is emerging as one of the most rapidly advancing cathode chemistries, with recent projections suggesting that LFP's market share will continue to grow in the next decade. Recycling Li-ion battery cathode materials using aluminum waste, such as current collectors, aluminum swarf, and aluminum dross, through aluminothermic reduction offers a resource-efficient process that eliminates the need for energy-intensive reductants. This study investigates the mechanism and kinetics of aluminothermic reduction of LFP at various temperatures and atmospheres using a solar-simulator furnace. The proposed approach seeks to address the limitations of the pyrometallurgical battery recycling process by developing a recycling method that utilizes secondary-resource reductants and renewable heat source. The information and data obtained are useful in determining the optimized parameters of recycling end-of-life LFP batteries via the pyrometallurgical route. |
