The invention discloses a high-dispersity Prussian blue nano particle/high-crystalline carbon composite material and a preparation method thereof. The preparation method comprises the following steps: dissolving iron salt in acetone, adding solid sodium hydroxide, uniformly mixing, and standing for reaction to obtain iron-containing carbon quantum dots; and roasting the iron-containing carbon quantum dots and a nitrogen-containing organic micromolecular compound in a protective atmosphere, and washing and drying the roasted product to obtain the high-dispersity Prussian blue nano particle/high-crystalline carbon composite material. The Prussian blue nano particles and the three-dimensional carbon nano flowers in the composite material are compounded in-situ, the Prussian blue nano particles are uniformly dispersed and firmly embedded on the three-dimensional carbon nano flowers, the Prussian blue nano particles are good in stability and not prone to falling off, the crystallinity of the carbon nano flowers wi
