Recovery of FeSO4·H2O, FePO4·2 H2O and Li3PO4 products from spent LiFePO4 black power materials via acid leaching, stepwise selective crystallization and precipitation
Key Points
The recovery process yields significant amounts of FeSO4·H2O and Li3PO4 from waste materials.
Key evidence shows that over 85% lithium recovery is achievable through selective crystallization techniques.
The method involves acid leaching followed by stepwise selective crystallization and precipitation for optimal product extraction.
This approach highlights the potential for sustainable recycling of lithium-ion battery materials, reducing environmental impacts.
