With the development of new energy vehicles, urgent issues have attracted considerable attention. Some power batteries have entered the scrapping period, with the imperative recycling of used power batteries. Some studies have predicted that by 2020, the amount of power lithium battery scrap will reach 32.2 GWh, corresponding to ~500,000 tons, and by 2023, the scrap will reach 101 GWh, corresponding to ~1.16 million tons. In this study, nickel-cobalt-lithium LiNi0.7Co0.3O2cathode materials are regenerated from spent lithium-ion battery cathode materials as the raw material, which not only aids in the reduction of pressure on the environment but also leads to the recycling of resources. First, extraction is employed using extracting agent p204 to remove aluminum ions from an acid leaching solution. Extraction conditions for aluminum ions are: include a phase ratio of 1:2,a pH of 3, an extractant concentration of 30%, and a saponification rate of 70%.Next, the precursor was prepared by co-precipitation using sodium hydroxide and ammonia water as the precipitant and complexion agents, respectively; hence, the cathode material can be uniformly mixed at the atomic level. The precursor and lithium hydroxide were subjected to calcination at high temperature using a high-temperature solid-phase method. The Calcination conditions include an air atmosphere ; a calcination temperature of 800° °C ; a calcination time of 15 h, an n (precursor): n (lithium hydroxide) ratio of 1:1.1.The Thermogravimetric analysis revealed that the synthesis temperature should not exceed 850°C. X-ray diffraction analysis, scanning electron microscopy, and energy spectrum analysis of the cathode material revealed a composition comprising Li, Ni, and Co oxides. After analysis, the material obtained is lithium nickel-cobalt-oxide, LiNi0.7Co0.3O2, which is a positive electrode material with good crystallinity and a regular layered structure.
