Negative Electrode Sheet Recycling Machine

Lithium-ion batteries (hereinafter referred to as lithium batteries) have been rapidly occupying the power source market of portable electronic and electrical equipment since their commercialization because of their significant advantages such as high voltage, high specific capacity, long life and no memory effect, and the output is increasing year by year. Lithium batteries are electronic consumables with a service life of about 3 years. If the end-of-life lithium batteries are not properly disposed of, the lithium hexafluorophosphate, organic carbonate and heavy metals such as cobalt and copper will definitely pose a potential pollution threat to the environment. In order to alleviate the increasingly serious problem of resource shortage and environmental pollution caused by rapid economic development, it has become a global consensus to realize the recycling of all components of waste materials. The copper (content of about 35%) of waste lithium battery negative sheet is an important production material widely used, and the carbon powder adhered to it can be used as an additive for plastics and rubber. Therefore, the effective separation of the constituent materials of waste lithium battery cathodes is a driving force for the resourcefulness of waste lithium batteries to a high extent and the elimination of their corresponding environmental impact. Commonly used waste lithium battery treatment methods include wet, thermal and mechanical-physical methods. Compared with the wet and fire methods, the mechanical-physical method does not need to use chemical reagents and consumes less energy, which is an environmentally friendly and effective method. Based on the structural characteristics of Li-ion battery negative, our company adopts a combination of crushing and screening and airflow sorting process to separate and screen them, so as to realize the recovery of aluminum and carbon powder in the waste Li-ion battery negative.
