Abstract

The efficient recycling of valuable metals such as lithium, cobalt, and nickel contained in waste lithium batteries is of great significance for resource recycling and environmental protection. This paper proposes a green and efficient recycling process. By optimizing the key technical parameters in the processes of dissolution, separation, and purification, the high-efficiency recycling of the above-mentioned valuable metals is achieved. The research results show that this process can not only significantly improve the recovery rate of valuable metals but also demonstrate obvious advantages in reducing environmental pollution. Through the quality evaluation of the recycled products, the feasibility and economic efficiency of this process are verified. This study provides a new idea for the recycling of valuable metals in waste lithium batteries and helps to promote the development and application of related technologies.
