Lithium battery wet recycling process.12v 100ah deep cycle battery

　　The wet recycling is mainly to dissolve the metal ions in the lithium phosphate battery through the acid -base solution. It further uses precipitation and adsorption to extract the dissolved metal ions in the form of oxides, salt and other forms. Most of the reaction process uses H2SO4, NaOH and H2O2 and other reagents. The wet recycling process is simple and the equipment requirements are not high. It is suitable for large -scale industrial production. It is the most studied by scholars and the mainstream waste lithium ion battery treatment route.

　　The recovery of lithium iron phosphate battery wet method is extremely important. When the wet method recycled the lithium iron phosphate positive pole, the aluminum foil collective fluid must be separated from the positive active substance. One of the methods is to dissolve the alkaline fluid with alkaline liquid, and the active substance does not respond to the alkali solution. The active substance can be obtained by filtering. The second method is to dissolve the PVDF with organic solvents, so that lithium iron phosphate orthopedic materials are separated from aluminum foil, aluminum foil is re -used, active substances can be treated follow -up, and organic solvents can be distilled to achieve their circulation. Compared with the two methods, the second is more environmentally friendly and safe. The recovery of lithium iron phosphate in the positive electrode is to generate lithium carbonate. The cost of this recycling method is low and is adopted by most lithium iron phosphate recycling enterprises, but the main component of lithium iron phosphate (95%) has not been recycled, causing waste of resources.

　　The ideal wet recycling method is to convert waste phosphate's lithium consignment materials into lithium salt and iron phosphate, and realize the full element recycling of Li, Fe, and P. If you want to become a lithium salt and iron phosphate, you need to oxidize the metal oxidation into a three -valent iron. Some scholars use oxidation to separate aluminum slices and lithium iron phosphate. After leaking out of sulfate and separation, coarse phosphate, and the solution removal of sodium carbonate to precipitate lithium carbonate. Crude iron phosphate further refine the battery -grade iron phosphate and can be used for preparation of lithium iron phosphate material. After years of research, this process has been relatively mature
