Embodiments of the present disclosure relate to the technical field of
chemical engineering process scale-up, and specifically provide a process parameter optimization method and device for large-scale production of ternary positive
electrode materials. The method comprises: obtaining reference data corresponding to a target process section of large-scale production of ternary positive
electrode materials, the reference data including a set of
pilot process parameter values, a set of
pilot quality detection values, and a set of large-scale
production quality target values; retrieving matching historical data from a pre-set historical
database, the historical data including historical process parameters and quality detection data of
pilot and large-scale production; using a process parameter optimization model corresponding to the target process section, obtaining a set of predicted values of large-scale production process parameters based on the above data; carrying out large-scale
process verification according to the predicted values, if the deviation between the actual value of the verified product quality and the quality target value meets a pre-set condition, determining the set of optimized process parameters, otherwise adjusting the parameters and iteratively verifying until the pre-set condition is met.
