Lithium batteries have a wide range of uses, and it is worth considering how to deal with the waste lithium-ion batteries that accompany them. In 2015, new energy vehicles were promoted in the form of subsidies for the purchase of new energy vehicles, which led to an explosive growth in the installed capacity of lithium-ion batteries; accordingly, the number of retired lithium-ion batteries in the end-of-life stage of the product also increased dramatically. The life of lithium-ion batteries in cars is usually 4-6 years, so in the next few years there will be a wave of new energy vehicle retirement, and the recycling and treatment of used lithium-ion batteries has become a huge market.
The recycling of used power batteries is a "regeneration production line", which is a kind of recycling equipment that is friendly to the environment, and is a key link in the whole battery life cycle, and has a very important role in the industrialization of new energy vehicles. In the recycling process, the recycling of used lithium batteries is mainly in the crushing, battery crushing treatment technology is usually different from one manufacturer to another.
Applicable battery recycling range: lithium iron phosphate batteries, ternary lithium battery technology.
The main processing technology: oxygen-poor charged crushing (with inert gas protection)
Lithium-ion battery charged crushing production line processing process: the crushed charged lithium battery materials (with inert gas protection) directly into the oxygen-free cracking system, charged lithium battery heating in the cracking system discharge heat to make secondary use of charged electricity, while the electrolyte, plastic film, plastic and adhesives and other organic materials for their own cracking, cracking gas generated by the purification of the cracking system for heating, cracking materials after After cooling, iron, nickel, aluminum, copper and stainless steel are sorted out by magnetic separation and wind selection, and then the cracked pole pieces are sorted out by friction de-powdering and screening and grading to separate the pole powder and metal particles, and the metal particles are then separated from copper and aluminum by grading and specific gravity sorting. All kinds of waste gas, cracking gas and vacuum generated by the integrated combustion system combustion heating, combustion exhaust gas through cooling spray, water vapor separation and adsorption for standard emissions.
Lithium-ion battery charged crushing advantage: there is inert gas protection crushing, to ensure production stability, safety and environmental protection, and charged lithium batteries in the cracking discharge heat can allow electricity to be reused, reducing discharge input and production costs.
Waste lithium-ion battery recycling and reuse can resource the waste lithium batteries, recycling cobalt, lithium, toner, copper, aluminum recycling. Let the waste lithium battery component materials for effective separation, for the maximum realization of waste lithium battery resources, to eliminate its corresponding environmental impact has a driving role. New energy vehicles do the main power of waste batteries can be recycled, both to obtain economic benefits and reduce environmental pollution, the global automotive industry will usher in a new development.
