Abstract:With the development of the new energy vehicles industry, the output of vehicles power batteries is growing rapidly, and the amount of discarded power battery is also increasing year by year. In order to realize the recycling of valuable elements in spent power batteries, reduce the pollution of waste to environment and alleviate the contradiction between supply and demand of lithium and cobalt resources, the recycling of spent power batteries is extremely urgent. Ternary cathode material is the most valuable recycling component in the spent vehicles power batteries. The technological progress of hydrometallurgy, combined pyrometallurgy and hydrometallurgy extraction technology, and other extraction technologies of waste ternary power battery cathode materials were summarized. The advantages and disadvantages of various technologies were analyzed. The research direction of the extraction technology of valuable elements from the cathode materials of waste ternary power battery was prospected.
