Recycling and Treatment Technology of Waste Lithium-ion Batteries
The recycling and treatment technology of waste lithium-ion batteries mainly includes three methods: physical separation, biochemical treatment, and chemical treatment. Physical separation includes flotation method and grinding method, which has poor separation effect and low metal recovery rate. Biochemical treatment utilizes microorganisms to catabolize battery materials and selectively leaches specific elements, but it is still immature and has no practical application. Chemical treatment is a widely used recycling treatment method, and many related researches are carried out. It is mainly divided into three categories: fire process, wet process and electrode regeneration.
After years of research and development, SUNY GROUP has a complete production line of waste lithium battery recycling equipment, which can selectively shred materials, and then adjust the parameters of air selection to explore the physical factors such as density, shape, particle size and other physical factors to separate and recycle materials. The degree of influence of efficiency. The crushing and air separation method has high recovery efficiency, no chemicals are used, secondary pollution is avoided, and a dust collection and collection device needs to be installed. Under the action of airflow, the solid particles are sorted according to density, shape and particle size, and the solution is obtained. The air selection parameters of the crushed products of the waste power battery are 0.20-22.00mm, and the copper and aluminum with a particle size of 5.00-22.00mm are selected in the test, and the separation rate is as high as 100%.
At present, the treatment technology of waste lithium batteries is becoming more and more mature. The combined use of various process equipment and the direct regeneration of cathode materials will become the development trend of lithium battery treatment in the future, and the composite treatment technology with low energy consumption, less pollution and easy operation will become the main development direction.
With the development of battery research and industrialization, lithium-ion batteries have been popularized in many aspects of modern society, but the accompanying environmental pollution also faces severe challenges, and lithium-ion batteries contain a large amount of metal elements. Therefore, from the perspective of sustainable energy development and the environment, turning waste into treasure and recycling has become an effective means. It is believed that the recycling technology and equipment of lithium batteries will be more perfect and mature. As a professional manufacturer of waste lithium battery recycling equipment, SUNY GROUP welcomes friends in need to cooperate and communicate.
