The present invention discloses a lithium-ion power battery positive electrode material slurry preparation method, which comprises mixing various components of a positive electrode material slurry, wherein the mixing specifically comprises: 1, using a three-shaft stirrer to carry out dry mixing on a positive electrode active substance, an electric conduction agent and a binder, 2, adding partial solvent to the three-shaft stirrer, and carrying out primary dispersion, and 3, transferring the dispersed slurry to a planetary stirrer, adding the remaining solvent, and carrying out secondary dispersion. According to the present invention, the dry mixing process is used, the solvent is gradually added to the solid powder, and the high solid content of the system is utilized to improve the dispersion effect; and the three-shaft stirrer and the planetary stirrer are combined so as to achieve the good mixing effect.
