Upgraded Lithium-Ion Battery Recycling System
With the rapid development of new energy vehicles and the energy storage industry, the volume of retired lithium-ion batteries continues to rise, placing higher demands on the safety, stability, and recovery precision of recycling equipment. SUNY GROUP's upgraded lithium battery recycling system focuses on three core objectives: safety first, precise sorting, and high-value recovery. It has systematically optimized key equipment and processes, significantly enhancing overall operational efficiency and material recovery quality.
Multiple Core Equipment Upgrades
The front-end processing stage adopts a sealed crushing structure and incorporates a nitrogen protection system. This effectively isolates oxygen during crushing, reducing the risk of combustion or explosion caused by residual electrolyte and ensuring long-term continuous operational safety. The upgraded electric heating pyrolysis furnace replaces traditional heating methods, enabling more precise temperature control. This facilitates the stable decomposition of internal organic materials, creating optimal conditions for subsequent physical separation while delivering higher energy efficiency and operational stability.

Refined Sorting Process
During the core material recovery stage, the system significantly enhances black powder processing capabilities. A newly upgraded water-cooling system effectively controls material temperature, reduces metal adhesion, and enhances black powder recovery rates at the source. Concurrently, an ultra-fine grinding system is introduced to perform more precise dissociation processing on materials. This thoroughly separates active substances from metallic impurities, significantly improving black powder purity. Aluminum content can be stably controlled below 0.5%, providing high-quality raw materials for subsequent hydrometallurgical or pyrometallurgical processes.
High-Value Metal Separation Design
For copper-aluminum separation, the system incorporates optimized inclined screening equipment and air classification structures. Leveraging physical property differences achieves efficient separation, markedly improving the purity and market value of copper and aluminum products. Combined with carbonization treatment and air classification units, the entire production line forms a multi-stage process from crushing, pyrolysis, and sorting to refining. This ensures material recovery rates while balancing environmental protection and automation requirements.
Overall, this upgrade to the lithium-ion battery recycling system represents a qualitative leap in safety protection and equipment stability. It also achieves breakthrough progress in black powder purity and metal recovery value, providing a more competitive equipment solution for large-scale, standardized lithium battery recycling.
