Waste lithium iron phosphate batteries were initially soaked in 5wt% NaCl solution and discharged for 48 h. Then, the discharge battery was manually disassembled and separated, and the pure cathode and anode materials were obtained from the cathode and anode plates, respectively.
In this paper the most recent advances in lithium iron phosphate batteries recycling are presented. After discharging operations and safe dismantling and pretreat-ments, the recovery of materials from the active materials is mainly performed via hydrometallurgical processes.
Efficient separation of small-particle-size mixed electrode materials, which are crushed products obtained from the entire lithium iron phosphate battery, has always been challenging. Thus, a new method for recovering lithium iron phosphate battery electrode materials by heat treatment, ball milling, and foam flotation was proposed in this study.
Despite its numerous advantages, lithium iron phosphate faces challenges that need to be addressed for wider adoption: Energy Density: LFP batteries have a lower energy density compared to NCM or NCA batteries, which limits their use in applications requiring high energy storage in a compact form.
