Lithium-ion recycling plant and machinery

In view of the low recovery rate of waste lithium-ion battery negative treatment process, easy to produce secondary pollution, the material is difficult to be further recycled and other defects, SUNY GROUP proposed the use of crushing method to crush the lithium-ion battery negative material recycling equipment can be recovered negative copper and graphite and other metal process. The negative material of lithium-ion battery is an important part of the lithium-ion battery, and the composition and structure of the negative material has a decisive influence on the electrochemical performance of the lithium-ion battery. From the brief history of the development of lithium-ion batteries, the development of negative materials has led to the commercialization of lithium-ion batteries. Lithium batteries use metal as the negative material, but the metal is easy to produce lithium dendrites during charging and discharging and lead to fire and other safety problems. Then lithium alloy materials were developed to solve the above safety problems, but the alloy materials are prone to volume expansion during lithium embedding and de-lithiuming, leading to a decline in cycle performance. Later, after further research and comparison, graphitized carbon was selected as a commercial negative material for lithium-ion batteries.

Lithium battery structure

SUNY GROUP produces new waste lithium-ion battery separation and recycling equipment production line and treatment process, all using mechanical knocking, crushing, separation and other physical treatment methods to recover and separate the positive and negative materials in lithium batteries, the whole process does not add any chemical ingredients, does not use any chemical treatment process, green ecological and environmental protection. Waste lithium-ion battery separation and recycling equipment can realize the complete operation of separating and recycling the positive and negative materials of waste lithium batteries, without the need for other equipment, the process is complete and easy. In addition, it includes lithium battery scrap feeding device, crusher, airflow sorting screen, crusher, analyzer, first grading screen, second grading screen, first specific gravity sorting machine, second specific gravity sorting machine, induced fan, collector and pulse purifier. The lithium battery waste is transported to the crusher for crushing, and the material crushed by the crusher is firstly transported to the airflow sorting screen, and the material separated from the diaphragm paper pieces by the airflow sorting screen is transported to the crusher, and then to the analyzer, which separates graphite powder and lithium cobaltate mixed powder and metal waste; the graphite powder and lithium cobaltate mixed powder are transported to the collector by the induced draft fan; the metal waste from the analysis is further The metal scrap is further sorted and separated. Waste lithium battery separation and recycling equipment production line can realize the complete operation of recycling and separation of waste lithium batteries, without the need for other equipment to cooperate, with thorough separation of cobalt and aluminum, high purity, high automation and fast production efficiency.

Lithium battery recycling equipment manufacturing

Lithium battery and other raw materials into the hammer crusher to adhere to the negative copper foil surface of the carbon powder and acetylene black powder for hammering vibration stripping; in the lower part of the hammer crusher rotor set sieve plate, by hammering crushing less than the aperture of the sieve plate negative particles through the small holes in the sieve plate fall into the screening equipment below; size greater than the aperture of the sieve plate negative material in the hammer crusher is cyclic hammer vibration crushing, until the size is less than the aperture of the sieve plate; fall into the screening The crushed particles falling into the screening equipment use the size difference and shape difference between the particles to achieve the separation of metallic copper and non-metallic carbon powder and acetylene black powder after the hammer vibration stripping through the screen.

Waste lithium battery recycling equipment is mainly used for lithium-ion battery manufacturers to separate aluminum, copper and positive and negative materials in the end-of-life positive and negative pieces for the purpose of recycling. The complete set of equipment operates in the negative pressure state, without dust outflow, and the separation efficiency can reach more than 98%. As the application of lithium-ion batteries becomes more and more widespread, it is important to recycle the valuable metals in lithium-ion batteries, reduce the pollution caused to the environment and alleviate the problem of resource scarcity.

The rapid development of cell phones, notebook computers, digital cameras, models, electric toys, electronic devices, electric vehicles and hybrid cars and other industries have produced a large number of waste lithium batteries, the recycling of lithium batteries, SUNY GROUP waste lithium batteries separation and recycling equipment production line will be useful materials in lithium batteries recovery, the separation and purification of metals and non-metals, has a very good market development prospects.
