The direct regeneration of deeply deactivated ternary cathode materials can effectively reduce energy consumption and alleviate environmental burdens，achieving clean recycling and reuse of lithium-ion batteries. However，it has been found that the direct regeneration of materials dismantled often has poor effects. Therefore，research on the characteristic analysis and pretreatment of deeply deactivated ternary cathode materials from retired lithium-ion batteries was conducted. A systematic study of the deactivated cathode materials using various characterization techniques showed that the deeply deactivated ternary cathode materials contained a significant amount of binder PVDF，conductive carbon black，and salt impurities，and their crystal structure was severely damaged. Moreover，electrochemical results showed that the specific capacity was only 30 mA·h/g，which was far below that of commercial material，indicating a significant degradation in battery capacity. In order to effectively regenerate the ternary cathode materials，a high-temperature calcination pretreatment for impurity removal was carried out in an oxygen atmosphere. Calcination at 550 ℃ for 4 h could completely remove conductive carbon black and other impurity components from the deactivated cathode materials，without significantly affecting the composition and structure of the materials，thus laying the foundation for subsequent processing such as direct regeneration.
