| Abstract Scope |
With the widespread use and limited lifespan of lithium iron phosphate (LFP) batteries, the generation of spent batteries is increasing significantly, posing environmental hazards and risks of incidents like explosions and fires. Recycling these batteries is crucial for mitigating risks and reclaiming valuable resources, particularly lithium, which is the most valuable component in LFP batteries. The lithium recovery rate from these batteries is less than 1%, highlighting the need for improved recovery technologies. Selective leaching, a green, simple, cost-effective, and sustainable method, has garnered significant attention. This paper reviews various selective leaching methods, evaluates their feasibility, and provides a comprehensive comparison based on cost, complexity, and environmental impact, emphasizing selective leaching's promise for LFP battery recycling. |
