The value of lithium batteries
From the current technology, if the availability of waste ternary lithium-ion batteries is very small, there is no special technology to make more effective; because the waste ternary lithium-ion battery has heavy metals and chemical components inside, it must be specially treated to prevent pollution. The current technology is not too mature.
For the use of waste lithium batteries, we know that cobalt, lithium, copper and plastics in waste lithium batteries are valuable resources and have extremely high recycling value. Therefore, the scientific and effective treatment and disposal of waste lithium batteries not only has significant environmental benefits, but also has good economic benefits. In order to alleviate the increasingly serious resource shortage and environmental pollution caused by rapid economic development, it has become a global consensus to realize the full-scale recycling of used lithium batteries.
The waste ternary lithium ion battery is mainly composed of a casing, a positive electrode, a negative electrode, an electrolyte and a separator. The positive electrode is formed by coating the lithium cobaltate powder on both sides of the aluminum foil current collector through the bonding PVDF; the negative electrode structure is similar to the positive electrode, and is composed of carbon powder bonded to both sides of the copper foil current collector. For the recycling of used lithium batteries, the commonly used methods for recycling lithium batteries include hydrometallurgy, pyrometallurgy and mechanical physics. Compared to wet and fire methods, lithium battery shredders use mechanical physics without the use of chemical reagents and with lower energy consumption, making them an environmentally friendly and efficient method.
Recycling waste lithium battery processing to make money, investing in Kaidi mechanical lithium battery pulverizer equipment, which is based on the material characteristics of the positive and negative structures of lithium batteries and their constituent materials of copper and carbon powder, using hammer vibration crushing, vibrating screening and airflow sorting combination The process separates and recovers the negative electrode constituent materials of the waste lithium battery.
At present, the annual mobile phone battery is about 100 million discarded. Each lithium iron phosphate lithium ion battery weighs about 20g on average, of which the cobalt content is about 3g. At present, the price of metal cobalt is 400,000 yuan/ton, and the recycling of waste metal per ton is 160kg. Above, the value is 64,000 yuan, and the recycling value of cobalt alone can reach several hundred million yuan. Aluminum, copper and organic electrolytes can also be recovered from used lithium ion secondary batteries, which are of high value. The cost of re-recycling is mainly the power consumption, labor costs, raw materials, transportation costs, and enterprise management fees for mechanical equipment operation, and the recycling cost of used batteries. Under the support of an effective waste mobile phone battery recycling system, it is expected that the annual processing capacity will be 100t, the annual sales income will reach at least 22.5 million yuan, and the profit and tax will reach 4.5 million yuan. The recycling of waste lithium-ion batteries can realize the recycling of materials and has a major society. significance.
The waste lithium iron phosphate lithium ion battery positive and negative electrode processing production line has abandoned the traditional high-energy and high-pollution recycling technology such as fire method and wet method, mainly adopting physical recovery method, supplemented by “three wastes” disposal measures, with low green Carbon, energy saving and environmental protection, no secondary pollution, and taking into account economic and environmental benefits, not only the use of valuable components, but also the harmless treatment of harmful components. The whole recycling process has realized industrial automation, high recovery efficiency and strong processing capacity. The processing capacity per hour is 500 kg, the annual processing capacity is 5,000 tons, and the recycling rate of valuable components of waste lithium batteries is over 90%. With the increasing application of lithium-ion batteries, it is of great social and economic significance to recover valuable metals in lithium-ion batteries, reduce environmental pollution, and alleviate resource shortages.
Through the research on the recycling of used lithium-ion batteries, it can be found that the recycling method mostly focuses on the recycling of the positive active materials in the battery. In summary, according to the main key technologies and principles of recycling, the recycling technology of waste lithium batteries can be divided into three methods: physical method, chemical method and mechanical method. The lithium battery pulverizer equipment produced by Yingtong crushes the raw materials to less than 10mm with a coarse crusher, then enters the particle pulverizer for stripping and pulverization, and then enters the micro-powder classifier for separation treatment. The tail ash is collected by the rear cyclone separator and the pulse dust collector. The waste lithium battery positive and negative electrode sheet processing equipment is based on the material characteristics of the positive and negative electrodes of the lithium battery and the constituent materials of the copper and the carbon powder, and the composition of the negative electrode of the waste lithium battery is adopted by the combination of hammer vibration, vibration screening and airflow sorting. The material is separated and recovered, and the complete set of equipment operates in a negative pressure state without dust and diarrhea, and the separation efficiency can reach over 98%.
Yingtong Machinery is a professional manufacturer of waste lithium battery processing equipment. Its lithium manganate lithium ion battery crusher equipment is mainly used in lithium ion battery manufacturers. It is used to scrap aluminum and copper in copper and nickel.
