Lithium-ion battery mechanical and physical recycling technology
With the vigorous development of new energy vehicles, a large number of decommissioned power batteries need to be recycled. In 2022, 530,000 tons of decommissioned lithium-ion batteries will be produced. Generally, the power lithium batteries retired from new energy vehicles still have more than 70% energy remaining. After selection and testing, they can be further applied in many fields such as energy storage, distributed photovoltaic power generation, household electricity, and low-speed electric vehicles. It shows great reuse value. Metals such as cobalt, nickel, manganese, lithium, iron and aluminum can still be extracted from the waste power batteries that are going to be scrapped.
Lithium battery recycling and processing equipment will automatically process batches of batteries in a physically harmless manner to obtain positive electrode powder, negative electrode powder, copper powder, aluminum powder, separator, steel, etc., and various products can be recycled in the industry. Lithium battery recycling is based on the selection of advanced dry physical decomposition treatment technology to automatically disassemble the battery in an environmentally friendly manner. These batteries are first environmentally friendly and crushed by an automated production line, decomposing valuable metals such as waste positive electrode materials, copper powder, and aluminum powder.
Lithium battery recycling equipment adopts a multi-stage crushing method, which improves the crushing efficiency of the battery, and the desorption rate of the black powder on the battery current collector, and improves the recovery rate of the black powder; the pyrolysis treatment can effectively remove the battery debris There are binders, electrolytes and a small amount of plastic in the battery to realize the pollution-free treatment of invaluable components; multi-stage sorting is used to realize the accurate sorting of each component in the battery scrap step by step, so that the sorting The contents of other components in the selected components are less, and the recovery rate of the black powder is also improved.
Product features: 1. The combination of multiple equipments has a higher degree of sorting, and an integrated supporting production line. 2. The new technology of high-voltage electrostatic separation has a longer life and is more durable. 3. The equipment is stable, easy to operate, high in safety and easy to maintain.
There are about 15% cobalt, 14% copper, 25% iron, 4.7% aluminum, and 0.1% lithium in waste lithium-ion batteries. These metals are primary resources and have recycling value. The complete set of lithium battery crushing equipment crushes the raw materials with a coarse crusher to less than 10mm, and then enters the particle crusher for peeling and crushing, and then enters the micro-powder classifier for separation and treatment.
Lithium battery recycling equipment realizes the separation and collection of electrode materials, current collector metals, plastic diaphragms, and battery casings in waste lithium batteries through steps such as mechanical crushing, vacuum separation, vibration screening, specific gravity separation, and airflow separation. The separation and collection process does not introduce any chemical reagents, and the whole process is fully automated. It can collect and process electrolyte, dust, etc., and has the characteristics of high recovery efficiency, green and low carbon, environmental protection and energy saving, and easy industrialization.
Waste lithium battery recycling and processing equipment production line. At present, the research on waste lithium battery recycling mainly focuses on the recovery of high-value positive and negative electrode precious metals. Can this lithium battery recycling and processing equipment scientifically process and dispose of waste batteries? Not only has good Environmental benefits, but also has good economic benefits!
