However, the thriving state of the lithium iron phosphate battery sector suggests that a significant influx of decommissioned lithium iron phosphate batteries is imminent. The recycling of these batteries not only mitigates diverse environmental risks but also decreases manufacturing expenses and fosters economic gains.
Additionally, lithium-containing precursors have become critical materials, and the lithium content in spent lithium iron phosphate (SLFP) batteries is 1%–3% (Dobó et al., 2023).
Solid-phase, liquid-phase, and electrochemical methods have been reported for the regeneration of waste lithium iron phosphate positive electrode materials.
The synthesis methods of lithium iron phosphate mainly include: solid phase method and liquid phase method. The solid phase method includes: high temperature solid phase reaction method, carbothermal reduction method, microwave synthesis method, mechanical alloying method.
