How to deal with and produce waste lithium batteries after recycling? How to deal with and produce waste lithium batteries after recycling? With the development of my country's electronics industry, lithium batteries are used more and more, and there are more and more waste lithium batteries. How to recycle and dispose of these used lithium batteries has become an urgent problem to be solved. Therefore, scientific and effective disposal of waste lithium batteries not only has obvious environmental benefits, but also has good economic benefits. How to deal with and produce waste lithium batteries after recycling? After pretreatment of waste lithium batteries, the composition of broken products is generally more complicated, including lithium battery shell, positive electrode data, negative electrode data, copper liquid collection, aluminum liquid collection, separation, electrolyte, etc. To be further separated. Recovery and utilization of precious metals recycling and utilization of precious metals recycling and utilization of precious metals recycling and utilization of precious metals recycling and utilization of precious metals recycling and utilization of precious metals recycling and utilization of precious metals waste of lithium batteries, we know that waste in cobalt lithium batteries, lithium, copper and plastic is precious Resources have a high recycling value. The waste lithium battery is mainly composed of a shell, a positive electrode, a negative electrode, electrolyte and separation. The positive electrode is formed by coating polyvinylidene fluoride (PVDF) lithium cobalt oxide powder as a binder on both sides of the aluminum foil collection solution. The structure of the negative electrode is similar to that of the positive electrode. Regarding the recycling of used lithium batteries, the commonly used recycling methods include hydrometallurgy, pyrometallurgy and mechanical physical methods. Compared with wet method and fire method, the lithium battery grinder adopts mechanical and physical methods, does not use chemical reagents, and has low energy consumption, which is an environmentally friendly and efficient method. Lithium battery retrieve.jpg(1) Physical sorting method Physical sorting method is a sorting method based on the particle size, density, and functional difference of magnetic materials. First screening, gravity separation, flotation, and magnetic separation. First, vertical shears, wind turbines and vibrating screens are used to classify the discarded lithium batteries, and the positive electrode data, negative electrode data, gap data and fluid collection data are obtained through crushing and sorting. After heat treatment of 500 positive and negative data, the flotation method is used to remove cobalt lithium and graphite. The recovery rate of lithium cobalt oxide can reach 97%. (2) Pyrometallurgy The method of pyrometallurgy is to abandon the lithium battery pretreatment, take off the battery case, and then mix the data to restore the baking, the binder and other organic gases escape, and the low-boiling lithium oxide escapes in the steam in most cases When water is absorbed, the metals of other metals (copper, nickel, cobalt, etc.) form alloys, which are subsequently produced by hydrometallurgical technology and solidified slag such as fluorine and phosphorus in the electrolyte. Merica International Co., Ltd. has a recycling plant in Oren, Belgium, with an annual processing capacity of 7,000 tons. my country's new energy vehicles mainly adopt pure electric mode, so the problem of power lithium-ion battery failure after the government expires has become a serious problem. my country's new energy vehicles mainly adopt pure electric mode, so the problem of power lithium-ion battery failure after the government expires has become a serious problem. The lithium battery recycling industry is of great significance. The pilot work of power lithium-ion battery recycling will promote the market to accelerate the improvement of the power lithium-ion battery recycling system. Lithium battery recall, the next industry will explode! Multi-billion-dollar lithium batteries are less toxic, so it doesn't make much sense to talk about their pollution. First, we can see the management and control of the manufacturing company. The management and control of chemical pesticide processing are very good. On the contrary, lithium battery processing companies have not implemented management and control, which cannot be ignored. According to the research report, power lithium-ion batteries will soon usher in the first wave of decommissioning. It is estimated that by 2020, the overall scale of the lithium battery recycling mall will reach 15.6 billion yuan. The recycling of ternary lithium battery resources may become dominant, and the business model of recycling network + professional processing framework is continuously optimized.
