Dry recycling process for waste lithium batteries

From the collection and sorting of waste lithium batteries to the recycling of black powder and the purification of metals, a highly efficient and low-burden resource regeneration process has been established.

Our recycling process is mainly divided into three stages.

Discharge crushing and exhaust gas treatment

Section A

Employing specialized technology, the process eliminates the need for time-consuming brine discharge, directly saving discharge time and high wastewater treatment costs. After disassembling the casing to obtain the battery cells, the equipment can break them into coarse particles in just 10 seconds using nitrogen explosion technology. It is also equipped with a multi-stage exhaust gas purification system including dust collection, spraying, activated carbon, and UV photolysis, achieving a conversion efficiency exceeding 99% and ensuring explosion-proof, leak-proof, and zero-pollution emissions.

Sorting process

Section B

Physical screening is performed based on differences in the size, density, magnetism, hydrophilicity/hydrophobicity, and conductivity of the debris. This stage can efficiently separate high-purity black mass, aluminum powder, and copper powder, with impurity content strictly controlled to an extremely low proportion (e.g., the aluminum/copper content of black mass is less than 3-4%).

Purification process and resource reuse

Section C

We refine black powder and rare earth elements, harmlessly process separators and anode materials, and efficiently recover metals (such as lithium, copper, and cobalt) or graphite from cathode materials, ultimately providing high-purity recycled products according to customer needs.
