Ternary lithium batteries are key products in the fields of new energy power and energy storage, with Ni, Co, and Mn serving as the core active elements in their cathode materials. With the arrival of the first wave of retired power batteries, how to achieve the resource-oriented recovery of valuable metals has become a critical issue. The selection of nickel, cobalt and manganese extraction equipment is now a major concern directly related to environmental safety and the sustainable development of the industrial supply chain.
Zhengzhou Tiei Extraction Technology Co., Ltd. has continuously carried out research on the recovery and extraction of nickel, cobalt and manganese from ternary lithium batteries. If retired batteries are not properly treated, the heavy metals, fluorides and organic electrolytes they contain can pose serious threats to ecological environments and human health. Therefore, the development of efficient and green recycling technologies is both urgent and essential.
In response to industry demands, Zhengzhou Tiei Extraction Technology has developed a complete integrated recycling process combining “pretreatment + hydrometallurgical centrifugal extraction,” enabling the efficient enrichment and separation of valuable elements such as nickel, cobalt and manganese. In this process, retired batteries first undergo physical discharging, dismantling and sorting to obtain electrode materials rich in active substances. The materials then enter the hydrometallurgical centrifugal extraction stage, where an acid leaching system is used to transfer metal ions into the liquid phase. Subsequently, the CWL-M series centrifugal extractors are employed to carry out multistage countercurrent extraction and stripping. Ultimately, high-purity metal products are recovered in the form of salts or oxides, while the extractants are recycled and reused, achieving both resource efficiency and process sustainability.
As the core equipment of the process, the CWL-M centrifugal extractor demonstrates significant advantages in the recycling operation due to its high mass-transfer efficiency and rapid phase separation capability. The equipment integrates mixing and separation functions within a compact process layout, greatly reducing equipment footprint. It operates with low energy consumption and minimal solvent residue, effectively reducing the burden of subsequent processing. In addition, the system allows flexible adjustment of throughput and phase ratios, adapting to material systems of different scales and compositions. Its fully enclosed design ensures operational safety and meets the requirements of green and environmentally responsible production.
This process has been successfully implemented by multiple battery recycling enterprises. It not only achieves metal recovery rates and product purities that meet customer requirements, but also delivers dual breakthroughs in both economic performance and environmental sustainability. Zhengzhou Tiei Extraction Technology offers full-process services ranging from process design and equipment supply to operational support, helping the retired lithium battery recycling industry advance toward a new stage of high efficiency, standardization, and sustainable development.
