How to recycle waste lithium batteries?

At this stage, the best equipment for recycling waste lithium batteries is the physical dry crushing and sorting method, which uses physical shredding, crushing, airflow analysis machines, sorting machines, etc. to separate and sort waste lithium batteries! Equipped with dust removal equipment, While recycling waste lithium battery resources, it also achieves environmentally friendly recycling and green recycling! The rare metals recovered and separated are of high value. The processing volume of the whole production line is 500-2000 kg per hour, and the automatic production saves time and effort!

From the perspective of the development of the ecological industry chain, waste lithium batteries contain a variety of important metal elements, such as cobalt and nickel in the positive electrode material. If the carbon material in the negative electrode is not recycled, it will have an impact on soil and water quality! Serious possible numbers It will be difficult to recover in ten years. At present, the treatment directions of waste lithium batteries mainly include recycling and recycling after cascade use. In fact, the ultimate goal is recycling.

The physical method of recycling waste lithium-ion batteries is to use the physical properties of various valuable components in waste lithium-ion batteries (color, density, magnetism, particle size, surface physical properties, etc.) to process valuable components in waste lithium-ion batteries method of separation. For example, the color separation of metal copper and aluminum can be used to separate them, the density difference between the diaphragm and the positive and negative electrodes and poles can be used to separate them by winnowing, and metal iron and other substances can be used to separate them. The ferromagnetic difference between them is separated by magnetic separation, and the separator, current collector and active material can be separated by sieving according to the difference in particle size of the material, and the difference between the surface physical properties of the positive and negative active materials can be used It is separated by flotation. The physical sorting method has the advantages of low cost and high sorting efficiency.

Since the material performance of various materials in waste lithium-ion batteries is good, and the performance of the recovered waste battery materials is not greatly reduced, it can be directly regenerated into battery materials after regeneration through certain technical means.

The recycling and utilization of waste lithium-ion batteries can be divided into four processes: recovery, pretreatment, separation of active materials, and recovery and reuse of positive active materials. The pretreatment process can be divided into processes such as disassembly, cascade utilization, and discharge. The separation of active materials can be divided into alkali leaching, heat treatment and solvent extraction, and the recovery and reuse of positive active materials can be divided into physical methods, chemical methods, combined physical and chemical methods and biological methods.
