The invention relates to a low-cost energy storage multilayer ceramic capacitor and a ceramic dielectric material and a preparation method thereof, the ceramic dielectric material comprises the following components in percentage: [awt% (Sr1-xCax) (Ti1-yZry) O3 + bwt% (10SiO2-Al2O3-zH3BO3)], a main base material is (Sr1-xCax) (Ti1-yZry) O3, a sintering aid is SiO2-Al2O3-H3BO3, a is more than 90 and less than 98, b is more than 2 and less than 10, and z is more than 0.5 and less than 1.5. Si and B doped mesoporous Al2O3 nanoparticles are synthesized by adopting an ultrasonic-assisted sol-gel method to serve as a sintering aid, and are distributed on the surface of the main base material through ultrasonic waves; growth of crystal grains of the main base material is effectively restrained, then the ceramic dielectric powder with the controllable crystal grain size and uniform distribution is obtained, the ceramic powder can be matched with a base metal electrode, and meanwhile the bias voltage characteristic of a capacitor is improved on the basis that the excellent electrical performance is guaranteed.
