- Abstract
In recent years, recovery of valuable metals from spent lithium-ion batteries (LIBs) has become important because of their high potential for environmental impacts and inability to use metallic resources sustainably. The amount of spent lithium iron phosphate (LFP) batteries is increasing daily as the use of LFP batteries from different LIBs types has become widespread due to low cost and high-security advantages. Accordingly, recovering valuable metals in spent LFP batteries is very important as most manufacturing and automotive companies are moving toward LFP materials. Spent LFP batteries have received less attention due to the small number of valuable metals they contain, although spent battery recycling methods have improved the economy, the environment, and human health. Developing economical Li recovery technologies is crucial for the long-term growth and benefits of the electric vehicle and spent LFP battery industries. The current review article reports the problems related to the recycling process of batteries, the need to extract valuable metals and possible procedures for battery recycling. Methods such as mechanical pre-treatment of cells, and hydrometallurgical process of the active cathode material appear to be the most efficient method option for spent LFP battery recycling. In addition, recovery of components and metals from active materials after discharge methods, safe removal, and pre-treatment is predominantly carried out by hydrometallurgical methods. The need for further scaling up of these technologies and the main challenges are presented and discussed here. It is believed the conducted review would be helpful in understanding the overall spent LFP battery recycling approach.
