New Lithium-ion Battery Recycling Equipment System
With the rapid development of new energy vehicles and the energy storage industry, the volume of retired lithium-ion batteries continues to rise. Safely and efficiently recovering their high-value materials has become a core challenge that the recycling industry cannot avoid. Against this backdrop, SUN GROUP's integrated lithium battery recycling equipment system, designed with a focus on sealed operation, safety, and high recovery rates, provides a more reliable solution for the physical crushing and front-end processing of lithium-ion batteries.
New Lithium-ion Battery Recycling Equipment System
I. Core Equipment and Process Structure
This integrated system comprises multiple core units that work in tandem, featuring low-speed, high-torque crushing equipment and efficient dissociation equipment. The front end utilizes a heavy-duty crusher designed for low rotational speed and high torque. Variable frequency drive precisely controls energy consumption and operational status, ensuring crushing efficiency while effectively reducing battery heating and sparking risks. The crushing chamber incorporates an inert gas interface, maintaining a controlled environment throughout processing.
During deep processing, the high-efficiency dissociation equipment utilizes a flywheel structure for load balancing, ensuring uniform stress distribution and thorough dissociation of internal battery materials. Critical components are constructed from high-wear-resistant steel and incorporate overload protection mechanisms, ensuring long-term stable operation under complex conditions. The replaceable screen structure allows flexible switching between different particle size requirements, creating optimal conditions for subsequent sorting and refining.
Through this integrated structure, black powder, copper, ferromagnetic metals, and plastics within lithium-ion batteries are efficiently released, providing clean, uniform material for downstream recycling processes.
II. Safety-First Sealed Design Philosophy
One of the greatest challenges in lithium-ion battery recycling stems from safety risks, particularly the potential for combustion or even explosion when residual electrolyte comes into contact with oxygen. Safety is prioritized from the initial system design phase, employing a fully enclosed, gas-tight structure to create an independent processing space.
During operation, continuous nitrogen injection displaces oxygen, establishing a stable inert environment during crushing and dissociation stages to minimize combustion and chemical reaction risks at the source. The main equipment features multi-seal door structures. Once materials enter, the system automatically completes sealing and interlock controls, ensuring the entire processing cycle occurs in a sealed state for maximum operational safety.
Material conveyance and processing follow an automated batch operation mode. Each batch undergoes complete processing within the system before the next batch automatically enters. This ensures continuous production capacity while eliminating safety hazards associated with frequent manual intervention.
III. High Capacity and Resource Recovery Value
While ensuring safety and stable operation, the system maintains exceptional processing capability, handling multiple tons of lithium-ion battery materials per hour per unit. Post-processing, batteries are dissociated into a mixture of smaller particles with a clear composition. This includes black powder rich in key elements like lithium, cobalt, and nickel, alongside directly recoverable copper, ferromagnetic metals, and plastics.
These output materials are highly suitable for subsequent drying, sorting, and refining processes. They demonstrate excellent compatibility whether serving as front-end processing systems for hydrometallurgical or pyrometallurgical methods, or as components within integrated recycling lines. Additionally, the compact design enhances flexibility in factory layout planning and project scalability.
Overall, by deeply integrating high-efficiency crushing, inert gas protection, and automated control, this equipment solution addresses safety, processing capacity, and resource recovery value for lithium-ion battery recycling. For enterprises seeking to enter or upgrade their lithium battery recycling operations, such highly systematic and engineered equipment undoubtedly represents a significant direction for industry development.
