The invention relates to a method for reducing fusion of crosslinked starch particles. The invention belongs to the technical field of starch-based activated carbon material preparation. The technicalproblem of cross-linking and hardening phenomena of starch particles is solved. According to the solution, starch, a cross-linking agent and deionized water are mixed to form starch slurry, then an alcohol coating agent and the starch slurry are mixed and dried to form dry starch particles uniformly coated with the alcohol coating agent, and finally monodisperse starch particles are obtained through cross-linking at the temperature of 150-200 DEG C. Because the alcohol coating agent has strong compatibility with the starch, the coated starch can effectively isolate starch particles with micro-nano sizes from melting. The method has a simple process route, and can improve the charring rate of the capacitor carbon, reduce the tar content and realize the monodispersity of the starch particles in industrial production.
