Development of Recycled Material Products from Waste Lithium-Ion Battery Recovery( I )

As the world undergoes a transition to clean energy, lithium batteries play a crucial role in this process. With the demand for lithium batteries rapidly increasing, a large number of waste lithium batteries will be generated in the future, making lithium battery recycling and material reuse critically important. Current recycling technologies typically target single-component lithium batteries. Our research team has developed an aqueous phase recycling technology that can effectively process various types of waste lithium battery black powder, ultimately obtaining high-purity products such as iron phosphate, manganese oxide, cobalt oxide, nickel hydroxide, and lithium carbonate. This project, based on previous industry-academic collaboration, focuses on developing applications for the recycled anode and cathode materials from lithium batteries. In the first year, the focus will be on developing recycled NCM cathode materials using coprecipitation technology. We will explore the control of the co-precipitation reaction to directly recover NCM cathode materials and discuss the impact of recycled material proportion adjustments on the final battery performance, providing the company with a basis for product competitiveness evaluation. Through this project, from the development of metallurgy recycling technology and the establishment of small-scale production equipment to the application development of recycled products, it is expected to significantly enhance the capabilities in the field of lithium battery recycling.
