In this study, lithium iron phosphate soft pack batteries with a nominal capacity of 30 Ah were employed, sourced from a waste recycling station in Hefei city. Electrochemical assessments unveiled an actual capacity amounting to merely 70 % of the initial capacity based on our repeated experiments (10 trials to get some similar retired batteries for collection).

Lithium iron phosphate batteries (LFPBs) have gained widespread acceptance for energy storage due to their exceptional properties, including a long-life cycle and high energy density. Currently, lithium-ion batteries are experiencing numerous end-of-life issues, which necessitate urgent recycling measures. Consequently, it becomes increasingly
Lithium iron phosphate. Lithium-ion batteries of different chemistries will differ in how much total energy they can provide in one charge, how quickly that energy is released, how stable the battery is, how quickly it can be recharged, and how many total times it can be charged and discharged, among other variables. Because of these differences, certain
Do not place the waste lithium batteries in the household trash or in curbside recycling bins. Instead, EPA recommends that all household lithium batteries be dropped off at battery collection sites (e.g., often located at electronics retailers) or household hazardous waste collection facilities for proper management.

Lithium-ion battery (LIB) use for autos was anticipated to reach $221 billion globally in 2024 [5]. As LiFePO 4 batteries have a lifespan of 5–8 years, a lot of used batteries will be generated in the future years [6]. In China, it is expected that about 313,300 tons of spent lithium-iron phosphate batteries would need to be recycled by 2030 [3].

High purity Li 2 CO 3 (99.95 wt%) could be obtained with a high recovery rate. This research demonstrates the possibility of improving the metal recycling effectiveness from spent LiFePO 4 batteries by incorporating the principles of green chemistry and probably contributes to the sustainability of the lithium ion battery industry.
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).
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.
