Lithium batteries have recycling value with the continuous development of technology, in advocating environmental protection on today, new energy technology has become more and more mature. Advanced technology is constantly updated, it is inevitable that some electronic waste will be generated. For example, batteries, lithium batteries, cell phone batteries, electric car batteries, energy storage batteries and so on. So many eliminated "retired" waste batteries, how should be to? If the disposal is not good will cause a lot of pollution to the environment, so lithium batteries have recycling value? With this question A Rong for everyone to introduce. Lithium battery recycling and reuse of new resources.
First, we need to understand the structure of lithium batteries. Used lithium batteries are mainly composed of: metal shell, positive and negative electrode, electrolyte, diaphragm, nickel, aluminum, copper and other important metal resources. Positive electrode: It is composed of PVDF by bonding lithium cobaltate powder evenly coated in the space on both sides of the aluminum foil. There are many types of positive electrode materials, such as: cobalt oxide, lithium manganate, lithium ternary, lithium iron phosphate, etc. Negative electrode: Its structure is similar to that of the positive electrode sheet, while it is composed of carbon powder bonded to the space on both sides of the copper foil. At present, the common international methods for recycling used lithium batteries are: wet metallurgy, pyrometallurgy and mechanical-physical methods. Wet metallurgy and pyrometallurgy require the use of certain chemical reagents in order to achieve a certain recovery effect. Mechanical-physical method does not require the addition of any chemical additives, and low energy consumption, because this recycling method is currently more environmentally friendly, and high recovery efficiency.
Therefore, the recovery of lithium batteries for the effective recovery of rare metals and resource recycling. Can achieve a certain economic value and recycling value. Lithium battery crushing and recycling equipment is mainly through the lithium battery positive and negative electrode sheet structure and other combined metal materials. Lithium battery recycling processing production line is the use of hammer vibration for effective processing crushing, and then through the vibrating screen for screening, airflow sorting and a series of combined recycling process, thereby effectively recycling the waste lithium battery separation and processing.
At present, cell phones are constantly being updated, resulting in a lot of scrap cell phone batteries, the annual scrap volume of cell phone batteries up to 100 million or so, common in each battery about 20g, its structure contains more than 3g of cobalt, which belongs to the chemical metal friends must understand the price of cobalt, up to 400,000 yuan per ton, each ton of used cell phone batteries can be recycled more than 160 kg, so the value of the metal The value of such metal is as high as 64,000 yuan. The annual value of cobalt recycling is up to hundreds of millions of dollars, and used lithium batteries also contain: copper, aluminum, nickel, electrolyte and other chemicals, the recycling value is very high. The cost of recycling used lithium batteries, including: lithium battery recycling equipment operating electricity, labor costs, company management, manpower and so on, the annual output of used cell phone batteries in about one hundred tons, (of course, according to the production capacity of lithium battery recycling equipment to determine,) then the income is prayer 22.5 million yuan, the profit tax can reach 4.5 million recycling used lithium batteries, to achieve the recycling of materials Use, resource recycling.
Waste lithium battery recycling equipment production line using physical and mechanical recycling process, has a green low-carbon, and energy-saving environmental protection, will not cause secondary pollution to the environment, so there are economic and environmental benefits, through the use of valuable components, there is a radical harmless treatment of harmful substances. The whole recycling process is automated, the recycling efficiency is high, the capacity will be born out very strong, the processing capacity is up to 500kg per hour, the specific recycling capacity can be decided according to the output of different equipment, you can consult Xingmao Environmental Protection for details, the recycling rate of waste lithium battery is up to 98 or more. It has great social significance and economic value.
