Summary:The invention relates to a method for preparing energy storage ceramic. A method for preparing energy storage ceramic with high breakdown strength is characterized by comprising the following steps of: 1) preparing Ba0.3Sr0.7TiO3 ceramic powder; 2) putting 21 to 50 molar percent of ZnO, 16 to 35 molar percent of B2O3 and 20 to 63 molar percent of SiO2 into a corundum crucible, melting at the temperature of between 1,200 and 1,500 DEG C, preserving the heat for 2 to 3 hours, taking out at a high temperature, quenching to obtain glass, drying the obtained glass fragments, and grinding to obtain glass powder; 3) adding the glass powder in an amount which is 2 to 8 percent based on the mass of the ceramic powder into the ceramic powder, performing ball milling, and drying; adding a binder, granulating, tabletting, and preserving the heat at the temperature of 600 DEG C for 2 to 3 hours to obtain ceramic sheets; and preserving the heat at the temperature of between 1,125 and 1,225 DEG C and the heating rate of 2 t
