With the rapid development of the new energy industry, lithium-ion batteries are widely used in consumer electronics, new energy vehicles, energy storage equipment and other fields due to their excellent performance, resulting in a continuous increase in market output and ownership. At the same time, a large number of retired and scrapped waste lithium-ion batteries are generated constantly. Containing various valuable metals such as cobalt, nickel, lithium, copper and aluminum, waste lithium-ion batteries are high-value renewable resources. Improper disposal and random abandonment will not only cause pollution to soil, water bodies and the atmosphere, aggravating ecological and environmental pressure, but also lead to serious waste of rare metal resources, depletion of primary mineral resources, and restrict the green and sustainable development of the new energy industry.
The resource recycling of waste lithium-ion batteries is a core track that balances environmental protection, resource circulation and economic benefits, delivering remarkable environmental, economic and social value. is deeply engaged in the field of new energy solid waste recycling equipment. We specialize in the R&D, production, upgrading and customized services of waste lithium-ion battery recycling and processing equipment. Focusing on the whole-process technologies of lithium battery pretreatment, material sorting and valuable metal recovery, we provide automated, efficient, environmentally friendly and high-recovery-rate complete equipment solutions for recycling enterprises, environmental protection factories and new energy industry chain enterprises, supporting the harmless, reduction and resourceful disposal of waste lithium batteries.
The complete resource recycling process of waste lithium-ion batteries consists of two core links: pretreatment and precision metal recovery and sorting. Relying on accumulated core technologies, optimizes equipment performance for each link and solves the industry pain points of traditional recycling processes, such as low efficiency, poor purity and secondary pollution.
Battery pretreatment is the fundamental and core procedure of lithium battery recycling, which directly determines the sorting accuracy and metal recovery rate of subsequent materials. The integrated pretreatment equipment of YuSai Precision Machinery realizes one-stop functions including safe discharge, intelligent disassembly, precise crushing and multi-stage screening. It can perform standardized pretreatment operations for various waste lithium batteries such as lithium cobalt oxide batteries, ternary lithium batteries and lithium iron phosphate batteries. The equipment can completely separate the internal components of batteries including positive plates, negative plates, separators and electrolyte. Through refined crushing technology, battery cores are processed into uniformly sized mixed powder materials, which thoroughly breaks the battery structure and lays a solid foundation for subsequent sorting and recovery of valuable metals.
In the core sorting and recovery stage, relying on the differences in physical properties of materials, YuSai Precision Machinery independently develops complete intelligent equipment integrating multiple core processes including screening, wind separation, magnetic separation, flotation and gravity separation. Adopting a physical sorting method without a large amount of chemical reagents, it realizes green recycling. According to the differences in particle size, magnetism, conductivity and specific gravity of crushed mixed materials, the equipment achieves precise separation and screening, and respectively purifies copper foil particles, aluminum foil particles, positive and negative electrode active material powder, graphite powder, plastic powder and other materials.
For the mainstream recycling scenario of waste lithium cobalt oxide batteries, our complete equipment supports standardized and efficient operation. After the precise crushing of battery cores by special crushers, primary sorting is completed through wind tables and multi-layer vibrating screens to accurately separate plastic impurities and mixed metal materials. Flotation and high-temperature debonding processes are then adopted to remove adhesives from positive and negative electrode materials and precisely separate graphite powder and lithium cobalt oxide active materials. With professional recycling equipment, the recovery rate of lithium cobalt oxide exceeds 97%, and the effective content of lithium and cobalt in recovered metal oxides is over 93%, keeping the resource utilization rate at the leading level of the industry.
Compared with traditional recycling equipment, the complete lithium battery recycling equipment of has prominent advantages. The equipment optimizes the hierarchical sorting logic and carries out differentiated treatment for materials with a critical particle size of 1mm. Small-particle materials are separated into positive electrode powder and carbon powder via flotation, while large-particle materials undergo precise sorting through high-precision magnetic separation equipment. The whole process adopts physical sorting technology without secondary pollution such as waste water and waste gas, fully complying with green environmental protection standards. To solve the common industry problem of low purity of recycled copper and aluminum metals that cannot be sold directly, we continuously iterate on equipment processes and core accessories to improve sorting accuracy and purification effects. This effectively enhances the purity of recycled copper and aluminum products, making recycled materials directly marketable and greatly improving the profitability of customers’ projects.
At present, the recycling industry of waste lithium-ion batteries has become a core part of the new energy circular economy, showing an obvious trend of standardization, intelligence and greening. Centering on industry demands and adhering to technological innovation, continuously optimizes the automation level, processing efficiency and recovery accuracy of lithium battery recycling equipment. We can meet the customized demands of large, medium and small-scale lithium battery recycling production lines, and provide one-stop services including equipment production, installation and commissioning, technical training and after-sales operation and maintenance. In the future, the company will continue to delve into the field of new energy solid waste resource utilization, iteratively upgrade recycling technologies and intelligent equipment, help customers reduce costs and increase efficiency, and promote the green and circular sustainable development of the lithium battery industry.
