Abstract: Due to the existence of valuable and hazardous materials, it is of great practical significance to carry out the recovery and regeneration of spent lithium-ion batteries with environment-friendly ways. With the characteristics of short treatment process, high efficiency and easy industrial application, pyrometallurgy has become the hotspot of spent lithium-ion batteries recycling. It can realize the recycling of valuable metals such as Li, Co and Ni based on the chemical transformation at high temperatures. This paper summarized the application of pyrometallurgy in the cathode material from spent lithium-ion batteries and its research status, including electrode materials dissociation, valuable metals recycling, the positive active material regeneration, etc,. Meanwhile, the advantages and disadvantages of different thermal treatment technology were analyzed and the research direction of the cathode material by pyrometallurgy in the future was also prospected.
