Lithium battery is mainly composed of shell, positive, negative, electrolyte and diaphragm. + is composed of PVDF coating lithium sulphate powder on both sides of the aluminum foil current collector;-structure is similar to +, it is made of carbon powder. It is formed on both sides of the copper foil current collector. Lithium-ion batteries have significant advantages such as high voltage, large specific capacity, long life and no memory effect. Since their commercialization, they have quickly occupied the power source market for portable electronic and electrical equipment, and their output has increased year by year. The service life is about 2 years. If the discarded lithium battery is improperly handled, the lithium hexafluorophosphate, carbonate organics and heavy metals such as diamond and copper will inevitably pose a potential pollution threat to the environment. On the other hand, the drill, lithium, copper and plastics in waste lithium batteries are precious resources and have high recycling value. Therefore, scientific and effective treatment of waste lithium batteries not only has significant environmental benefits, but also has good economic benefits.

1. Through the combined process of hammer crushing, vibrating screening and airflow sorting, the resource utilization of metal copper and carbon powder in waste lithium battery materials can be realized.

At present, research on the recycling of waste lithium batteries is mainly focused on the recovery of valuable precious metals and lithium, and there are few reports on the separation and recovery of materials. In order to alleviate the increasingly serious resource shortage and environmental pollution caused by rapid economic development, it has become a global consensus to realize full-component recycling of waste materials.
