In this study, we investigated the ability of Acidithiobacillus ferrooxidans to oxidize Fe2+ to Fe3+ and recover battery black powder, establishing a leaching system for decommissioned lithium iron phosphate battery black powder. Using ultrasonic waves, we aimed to enhance the leaching effect by removing impurities and promoting microbial activation through a cavitation reaction. A filter bag experiment was designed to explore the leaching mechanism of A. ferrooxidans, focusing on whether it was contact or non-contact based. Our findings showed that under optimal leaching conditions, the lithium leaching rate achieved 99.7%, reducing the leaching time from 7 to 5 days, thus demonstrating efficient leaching of lithium. The results concluded that the leaching mechanism of A. ferrooxidans for lithium iron phosphate primarily operated through a contact leaching approach, signifying an effective method for lithium recovery from waste lithium-ion power batteries.
