The lithium battery recycling system is mainly used to recycle discarded power lithium batteries, as well as small lithium batteries that are discarded from the production line or can no longer be used. The lithium battery recycling system includes three aspects: recycling, classification and reuse. Through the recycling system, the internal materials of lithium batteries can be separated using high-temperature melting technology. The materials can then be separated back into their original components and used to produce new batteries or other devices.
With the rapid popularity of electric vehicles and the rapid development of electronic products, the actual demand for lithium batteries has grown rapidly, and the subsequent treatment of used lithium batteries has attracted more and more people's attention. The harmless treatment of used and scrapped lithium battery recycling systems and the effective recycling of scarce metals such as cobalt, nickel, and lithium have gradually become the focus of research at home and abroad. At present, the processing technology of scrapped lithium batteries is becoming increasingly mature, and a variety of lithium battery process equipment. The combined use of positive electrode materials and the direct recycling of cathode materials will become the development trend of waste lithium battery treatment in the future.
Features
The comprehensive recycling and treatment equipment for waste lithium batteries has a high degree of automation and is easy to industrialize. All recycling processes have been automated, and the valuable components of waste lithium batteries have a recovery rate of over 99%. Lithium battery processing equipment separates aluminum, copper, and positive and negative electrode materials from discarded positive and negative electrode plates for the purpose of recycling. The aluminum content of positive and negative electrode materials is less than three thousandths, and the copper aluminum grade is ≥ 96%.
The complete set of waste lithium-ion battery crushing and sorting equipment mainly handles power, energy storage and 3C single lithium-ion batteries and battery waste. Including batteries with common specifications such as cylindrical, soft-packed, and square batteries, as well as battery waste such as defective battery products and scrap pole pieces. The end products are ternary/lithium iron black powder, copper powder, aluminum powder and battery casing.
Flow chart:
1.The live crushing device allows the battery to directly enter the crushing process without being discharged, which greatly improves the production scale and efficiency.
2. Precise oxygen control environment eliminates possible combustion and explosion during the process of electrified crushing and material pyrolysis.
3.The oxygen-controlled pyrolysis process directly carbonizes, volatilizes, and pyrolyzes the separator, electrolyte, PVDF, etc., shortening the process flow.
4.The crushing device and pyrolysis device are equipped with segmentally controlled blocking valves to effectively prevent the backflow of air flow.
5. Dry peeling device and comprehensive copper and aluminum sorting device, with ideal peeling and sorting effect.
6.Oxygen real-time monitoring + temperature segmented inspection + video monitoring + PLC + centralized chain control of the host computer improve the safety of the entire process.
