Abstract: To provide a method for predicting the c-axis length of a lithium compound crystal structure, a method for building a learning model for predicting a c-axis length, and a system for predicting a crystal structure having the maximum c-axis length. A method for predicting the c-axis length of a crystal structure of a lithium compound containing cobalt, nickel, and manganese includes preparing a descriptor including n values (n is an integer greater than or equal to 0) obtained by converting a crystal structure of the lithium compound in which manganese at any one or more of n sites is substituted by a metal atom among crystal structures of the lithium compound into binary data and a characteristic value of the metal atom; inputting the descriptor into a learned learning model; and outputting a predicted value of c-axis length of an optimized crystal structure and a descriptor corresponding to the optimized crystal structure as an output value of the learning model.
