The wet recovery of lithium iron phosphate batteries mainly focuses on the recovery of positive electrodes. When using a wet process to recover lithium iron phosphate cathode, the first step is to separate the aluminum foil collector from the active substance of the cathode. square
One method is to use alkaline solution to dissolve and collect the fluid, while the active substance does not react with the alkaline solution and can be obtained through filtration.
The second method is to dissolve the binder PVDF with an organic solvent to separate the lithium iron phosphate cathode material from the aluminum foil. The aluminum foil is reused, and the active substance can be further treated. The organic solvent can be distilled to achieve its recycling.
Compared to the two methods, the second method is more environmentally friendly and safe. One way to recover lithium iron phosphate from the positive electrode is to generate lithium carbonate. This recycling method has a lower cost and is adopted by most lithium iron phosphate recycling enterprises, but the main component of lithium iron phosphate, iron phosphate (with a content of 95%), is not recycled, resulting in resource waste.
The ideal wet recovery method is to convert waste lithium ferrous phosphate cathode materials into lithium salts and iron phosphate, achieving full element recovery of Li, Fe, and P. To convert lithium ferrous phosphate into lithium salts and iron phosphate, ferrous oxide needs to be oxidized to trivalent iron, and lithium is leached by acid or alkali leaching.
Some scholars use oxidation calcination to separate aluminum sheets and lithium iron phosphate, which are then leached and separated by sulfuric acid to obtain crude iron phosphate. The solution is then precipitated into lithium carbonate using sodium carbonate for impurity removal; The filtrate is evaporated and crystallized to obtain anhydrous sodium sulfate product, which is sold as a byproduct; Crude iron phosphate is further refined to obtain battery grade iron phosphate, which can be used for the preparation of lithium iron phosphate materials. After years of research, this process has become relatively mature.
