The invention discloses a method of measuring electrochemical kinetic parameters of an electrode active material. The method includes: measuring charging and discharging curves and cyclic voltammetry curve of a positive electrode; studying the charging and discharging curves according to data obtained by measuring and simulating the cyclic voltammetry curve according to Fick diffusion laws and formulas I, II, III and IV to obtain diffusion coefficient and interface reaction constant of the electrode active material. Compared with conventional Nernst equation fitting, the method has the advantages that interference of internal factors like concentration polarization can be eliminated, some characteristic parameters which are most intrinsic of the electrode active material can be reflected truly, and the method has quite high value in the field of academic research; a scientific method is provided for comprehensive and in-depth understanding of the electrode active material, and a theoretical basis is provided for designing batteries more reasonably.
