　　Lithium batteries have a large number of copper metal and lithium powder, are valuable precious metal resources, the market of used lithium batteries produced in tens of millions of tons per year, recycling these used lithium batteries have a high commercial value, the service life of lithium batteries in about 3 years, the current waste lithium batteries of many kinds, lithium iron phosphate, lithium cobalt acid, lithium manganate, lithium cell phone batteries, 18650 lithium batteries, lithium batteries, lithium batteries, lithium batteries, lithium batteries, lithium batteries, etc. Electric car batteries and a large number of waste lithium batteries, recycling these waste lithium batteries to be classified, the different types of lithium batteries bring different values, in the lithium ion negative materials, the proportion of copper metal and graphite, positive materials, the proportion of lithium cobalt acid aluminum metal.

　　The recycling process of waste lithium-ion batteries includes pretreatment, secondary treatment and deep treatment, as the waste battery still remains part of the power, so the pretreatment part includes deep discharge, crushing, physical sorting; secondary treatment aims to achieve the separation of positive and negative active materials from the substrate. So what metal materials can be recovered from the waste lithium battery crushing and de-powdering? Lithium battery recycling treatment equipment physical method process introduction.

　　The positive active material is lithium manganate or lithium cobaltate, lithium nickel cobalt manganate material, the positive powder obtained after processing by the lithium battery recycling equipment will be sold to downstream gold treatment enterprises for purification, purification as the electric material of lithium batteries.

　　The negative one active material is graphite, or carbon similar to graphite structure, and the conductive collector is electrolytic copper foil of 7-15 microns thickness.

　　At present, graphite is the mainstream commercial lithium negative material, its theoretical gram capacity is 372mAh/g, the better performance of graphite negative material on the market has been able to reach 360mAh/g, gram capacity gradually tends to the limit. The negative material obtained after the processing of lithium battery recycling equipment is sold to downstream gold treatment enterprises and other graphite industries.

　　The conductive collector of Li-ion battery negative uses copper foil, and the general thickness of Li-ion copper foil as the collector of Li-ion battery is usually between 7-20μm.

　　At present, new energy vehicles are equipped with copper foil thickness of 8-12μm, and the weight of the entire copper foil reaches more than 10kg. After the treatment of lithium battery recycling equipment in the form of copper powder is separated, copper powder will be recycled as raw materials for lithium batteries and applied in various copper products, so that the product is truly green recycling.

　　Lithium battery is the conductive collector fluid used is aluminum foil, electric car lithium battery is required to use aluminum foil, and requires the car itself as light as possible, and aluminum is the current preferred material for lightweight automotive parts, aluminum plays a vital role in the development of electric and hybrid vehicles.

　　In 2030, China's pure electric vehicle ownership will account for more than 30% of the total ownership, China's new energy vehicle industry to open up a new application area for the application of aluminum. The aluminum foil inside the lithium battery is separated in the form of aluminum powder after treatment by the lithium battery recycling processing equipment, and the aluminum powder is sold to downstream metallurgical enterprises and various aluminum products enterprises, truly achieving resource recycling without waste.

　　Diaphragm is one of the key internal structures of lithium battery, its role. Is separated from the positive and negative to prevent the battery short circuit, as the electrolyte is an organic solvent system, so the need for organic solvent-resistant diaphragm materials, the use of high-strength thin film diaphragm, lithium battery recycling equipment to obtain the diaphragm is used in a variety of plastic products.

　　Battery shell is divided into steel shell, aluminum shell, nickel-plated iron shell, aluminum-plastic film, battery cap. Due to the different types of battery shell materials, the lithium battery recycling equipment will be classified and processed to collect various types of shells for sale to different metallurgical enterprises as well as steel product enterprises.
