1. At this stage, the use of ladder use and raw materials for the use of lithium iron phosphate batteries/ternary lithium batteries. The method of staircase use is the recovery material after the use of the steps; the direct material recovery is too small, no historical check, and unqualified security monitoring. Pursuing economic benefits is the driving force for enterprises and social behavior. According to this principle, only when the available value of the battery is reduced below the maintenance cost, and then the raw materials are recovered, the value of the battery can maximize the value. However, the actual situation is that the traceability of early power lithium batteries is poor, and the quality and models are uneven. In the early stage, the echelon was risky to use batteries, and the cost of eliminating risks was high. Therefore, it can be said that in the early stages of the recycling of power lithium batteries, the disposal rate of the battery is mainly based on the recycling of raw materials

2. At present, the method of extracting a valuable metal from the positive material, that is, the recycling of the lithium iron phosphate battery pack, does not realize the comprehensive recycling and reuse of various materials on the entire battery. Important positive material types include lithium cobalt oxides, lithium manganate, ternary lithium, lithium iron phosphate ion battery, etc. The cost of battery positive materials accounts for more than 13 of the cost of a single battery. At present, more carbon materials (such as graphite) are used as cathode, and less lithium titanate LI4TI5O12 and silicon carbon anode SIC are less. Therefore, the current battery recycling technology is mainly aimed at the recycling of battery positive materials

3. Combined with the characteristics of the stable structure of lithium iron phosphate battery material, replacing traditional acid treatment and price recycling methods, direct regeneration, and obtaining high -performance regeneration LFP materials at a lower cost. At the same time, the process also realized the recycling of electrolytes and other materials, which greatly reduced the environmental pollution during the recycling process of lithium iron phosphate battery packs.
