With the rapid development of new energy vehicles and energy storage industries, a large number of lithium batteries have reached the end of their service life. Waste lithium battery shredding and sorting has become a key link in resource recovery and environmental protection.
Based on physical separation and closed-circuit operation, this technology realistically solves industry pain points such as difficult recycling, low separation efficiency and high pollution risks, turning retired batteries into reusable high-value materials.
Waste lithium batteries contain valuable resources including lithium, cobalt, nickel, copper and aluminum, but also pose risks such as flammable electrolyte and heavy metal pollution. Traditional rough handling not only wastes resources but also threatens safety and the environment.
The mature shredding and sorting process adopts multi-stage crushing, oxygen-free protection, physical sorting and tail gas purification. Without excessive chemical agents, it features stable performance and large-scale applicability.
In actual operation, waste batteries are fed in a sealed system and crushed under nitrogen protection. From coarse crushing to fine grinding, materials such as shells, pole pieces, separators and black powder are fully dissociated.
Through screening, air separation, gravity separation and magnetic separation, copper, aluminum, positive electrode powder and separators are accurately separated. The recovery rate of copper and aluminum can exceed 98%, and the powder purity meets the standards of renewable materials. The whole process is closed and negative-pressure operated with dust removal and waste gas treatment, realizing up-to-standard discharge without secondary pollution.
For enterprises, standardized shredding and sorting reduces raw material costs, meets policy requirements and improves market competitiveness. For the industry, it builds a closed loop of "use–recycle–regenerate–reuse", reduces the exploitation of primary mineral resources and ensures the supply of key metals.
Based on practical technology and reliable processes, waste lithium battery shredding and sorting truly turns waste into wealth, achieves safety, environmental protection and economic benefits, and provides a pragmatic and efficient solution for the lithium battery recycling industry.
