The invention relates to the technical field of energy storage of dielectric ceramic materials, in particular to a barium titanate-based ceramic material with high energy storage density and a preparation method thereof.The preparation method comprises the steps that BaCO3, TiO2, Bi2O3, MgO, ZnO and Na2CO3 are pre-sintered and subjected to heat preservation, barium titanate-based ceramic powder is obtained and put into a ball milling tank to be pretreated, then a first product is obtained after pressing and pre-sintering, and the first product is obtained; pouring the first product into a ball-milling tank, mixing, separating, pressing the obtained powder by using a mold to obtain a wafer, sintering the wafer in a muffle furnace according to sintering conditions to obtain the barium titanate-based ceramic material with high energy storage density, introducing strong ferroelectric Bi (Mg1/4Zn1/4Ti1/2) O3 and (Bi0. 5Na0. 5) TiO3 to form a uniform solid solution with a BaTiO3 antiferroelectric, and sintering the barium titanate-based ceramic material with high energy storage density to obtain the barium titanate-based ceramic material with high energy storage density. The maximum polarization intensity and the breakdown field strength of the ceramic material are improved, the energy storage density of the dielectric ceramic material is improved, and therefore the problem that an existing dielectric ceramic material is low in energy storage density is solved.
