How to recycle used lithium iron phosphate battery packs?

1. Echelon utilization and raw material recovery Decommissioned power lithium iron phosphate batteries. Those who take the road of cascade utilization are to recycle materials after cascade utilization; for straight material recycling, the batches are too small, there is no history to check, and the safety monitoring is unqualified. and many more. The pursuit of economic benefits is the driving force of company and social behavior. According to reason, cascading utilization, until the usable value of the battery is reduced to below the maintenance cost, and then raw material recovery, is the maximum value of the battery. But the actual situation is that early power lithium-ion batteries have poor traceability and uneven quality and models. In the early days, the risk of cascading use of batteries was high, and the cost of eliminating risks was high. Therefore, it can be said that in the early stage of power lithium-ion battery recycling, there is a high probability that the recovery of raw materials is the main place for batteries. 2. The method for extracting valuable metals from cathode materials. The current recycling of power lithium iron phosphate battery packs does not actually achieve the full recovery and reuse of various materials on the entire battery. The types of cathode materials mainly include: lithium cobalt oxide, lithium manganate, ternary lithium, lithium iron phosphate batteries, etc. The cost of battery cathode materials occupies more than 1/3 of the cost of single cells, and because the anode currently uses more carbon materials such as graphite, lithium titanate Li4Ti5O12 and silicon carbon anode Si/C are less used, so the current battery recycling technology is urgently targeted It is the recycling of battery cathode materials. There are three main types of recycling methods for waste lithium battery packs: physical method, chemical method and biological method. Compared with other methods, hydrometallurgy is considered to be an ideal recycling method due to its advantages of low energy consumption, high recovery efficiency and high product purity. 3. Combining the characteristics of stable structure of lithium iron phosphate battery materials, instead of using traditional methods such as acid solution and recycling of valuable elements, it is directly regenerated and solved, and high-performance regeneration is obtained at a lower cost. LFP material, at the same time, the process also realizes the recovery of electrolyte and other materials, which greatly reduces the environmental pollution during the recycling process of lithium iron phosphate battery pack. As a large number of lithium iron phosphate powered lithium-ion batteries are scrapped and entering the recycling stage, the battery recycling market has shown an explosive rise. In order to guard against secondary pollution to the environment during the recycling process, we must adopt more environmentally friendly recycling. Method. Lithium iron phosphate battery pack has the advantages of longer cycle life, high safety, low cost, and less environmental pollution, and has become the first choice of many domestic companies in the early stage of processing. Regarding the emergence of discarded lithium iron phosphate battery packs, if they are not recycled, they will cause huge environmental pollution. On the other hand, the effective recovery of metals and the utilization of surplus energy can also bring considerable economic benefits. Therefore, it is necessary for lithium battery processing companies to thoroughly study the current situation of recycling and solving waste lithium iron phosphate batteries.
