Due to the abundance of lithium in nature, recycling of lithium was not a priority for the many players in the lithium-ion battery, glass, or ceramics industries.The recent increase in demand for lithium for electric vehicles has emphasised the importance of recycling, and now both pyrometallurgical and hydrometallurgical flowsheets can recycle lithium from Li-ion battery …
Therefore, a comprehensive and in-depth review of the recycling technologies for spent lithium iron phosphate batteries (SLFPBs) is essential. The review provided a visual summary of the existing recycling technologies for various types of SLFPBs, facilitating an objective evaluation of these technologies.
Lithium iron phosphate (LFP) batteries have gained widespread recognition for their exceptional thermal stability, remarkable cycling performance, non-toxic attributes, and cost-effectiveness. However, the increased adoption of LFP batteries has led to a surge in spent LFP battery disposal.
The process was divided into five stages: safe pretreatment of batteries, removal of low-value collectors, leaching and extraction of high-value lithium, conversion of leaching residue into valuable materials, and regeneration of LFPB cathode electrode materials, which aimed to integrate various lithium-ion battery (LIB) recycling technologies.
At present, the overall recovery rate of lithium in waste LFP batteries is still less than 1% (Kim et al., 2018). Recycling technology is immature, the process is still complex and cumbersome, and it will cause pollution to the environment, so the current methods require further improvement (Wang et al., 2022).

In one approach, lithium, iron, and phosphorus are recovered separately, and produced into corresponding compounds such as lithium carbonate, iron phosphate, etc., to realize the recycling of resources. The other approach involves the repair of LFP material by direct supplementation of elements, and then applying it to LIBs again.
