Waste lithium iron phosphate (LFP) batteries consist of various of metallic and nonmetallic materials, with lithium being a critical strategic resource in the new energy era. Therefore, recycling LFP batteries has become a primary means of secondary lithium resource recovery.
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.
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.
This method offers a purified electrode material suitable for the subsequent hydrometallurgical recovery process, thereby presenting a novel approach to recovering waste lithium-ion batteries. Discover the latest articles, news and stories from top researchers in related subjects.
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.
This method, combined with other methods, can realize large-scale industrial recovery of lithium iron phosphate batteries at a small cost of lithium loss.
