The invention relates to a quality testing method of a ternary positive
electrode material, a medium and
terminal equipment, and the method comprises the steps: firstly, knowing the initial state of the material, and laying a foundation for subsequent changes; secondly, charging and discharging data and a structure change speed of a cycle period are collected, and a subsequent change direction and a process speed are established; the method comprises the following steps of: firstly, predicting charge-
discharge data of a next cycle period, and finally, continuously carrying out iterative prediction on new prediction data until charge-
discharge data after a final cycle number is obtained, so that the capacity
retention ratio after a final preset period can be determined, and whether the quality of the ternary positive
electrode material reaches the standard or not is judged according to the capacity
retention ratio. On one hand, various properties of the ternary positive
electrode material are comprehensively and systematically analyzed, and comprehensiveness is achieved; on the other hand, the experiment frequency can be effectively reduced, the labor intensity of workers and the time required for quality detection are reduced, the quality detection efficiency is improved, and the service life and customer satisfaction after delivery are improved.
