Abstract

With the rapid development of the renewable energy industry, the usage of lithium iron phosphate batteries has soared. Therefore, the recycling of spent batteries has become a social focus. The selective leaching method can effectively extract lithium, reduce impurities, and improve recycling efficiency. This paper systematically reviews various selective lithium leaching techniques, including chemical oxidation, acid-assisted leaching, electrochemistry, high-temperature roasting, mechanochemistry, and so on, which further compares their respective advantages and disadvantages from the aspects of technical economy and environmental benefits. The results indicate that the chemical oxidation method has advantages in cost control and operational flexibility, while the electrochemical method is more and environmentally friendly and green. For the selective recycling of spent lithium iron phosphate batteries, more efficient, environmentally friendly, and economical recycling solutions should be developed in the future. This will provide new ideas for exploring selective recycling strategies for lithium iron phosphate batteries, which can promote comprehensive and coordinated development of the economy, environment, and technology, and thereby build a virtuous cycle system of new quality productivity.
