The invention provides a battery slurry preparation method based on dry stirring. The method includes the following steps: adding an active substance and a binder into a stirring tank, and stirring for 0.2 to 0.4 hours; adding methyl pyrrolidone for the first time into the stirring tank, stirring for 0.4 to 0.6 hours, and controlling the temperature to be 18 to 23 DEG C; adding CNT conductive liquid into the stirring tank continuously, then continuously stirring for 0.4 to 0.6 hours, and controlling the temperature to be 18 to 23 DEG C; continuously adding methyl pyrrolidone for the second time into the stirring tank, and then continuously stirring for 2-2.5 hours in a vacuum environment, and controlling the temperature to be 18 to 23 DEG C to obtain slurry, wherein the proportion of methyl pyrrolidone added for the second time to methyl pyrrolidone added for the first time is 5: 5-3: 7. Compared with the prior art, the scheme of the invention can improve the sedimentation stability, rheological characteristics and dispersion uniformity of the anode slurry in a mixing process.
