[0002] In recent years, with the country's continued support for the new energy industry, the lithium-ion battery industry has experienced rapid expansion. China has become the world's largest producer and consumer of lithium-ion batteries. In the new energy vehicle sector, when battery capacity decays to 80% of its rated capacity, it no longer meets operational requirements, leading to the widespread retirement of lithium-ion batteries. Lithium-ion batteries contain a variety of toxic and hazardous substances, including heavy metals, organic and inorganic compounds. Improper disposal can cause significant pollution and waste resources.

[0003] Dry recycling is one of the current mainstream recycling methods. It mainly uses physical sorting after crushing to achieve the recovery of various components. This process will produce dust-containing exhaust gas, which requires dust removal. Bag dust removal is the most widely used dust removal method due to its high dust removal efficiency, simple structure, simple and reliable operation. Therefore, the demand for dust bags and the number of retired bags are also showing an increasing trend.
