Zr-doped high-entropy perovskite oxide ceramic material with high energy storage efficiency, preparation method and application thereof
The invention discloses a Zr-doped high-entropy perovskite oxide ceramic material with high energy storage efficiency. The preparation method of the material comprises the following steps: taking Na2CO3, Bi2O3, BaCO3, SrCO3, CaCO3, TiO2 and ZrO2 as raw materials according to the ratio of the chemical formula (Na0.2Bi0.2Ba0.2Sr0.2Ca0.2) Ti1-xZrxO3, carrying out wet ball-milling mixing on the powder, presintering the dried powder at 875 DEG C for 2 hours, after secondary ball milling, sieving and molding, finally sintering at 1300 DEG C for 2h to obtain the single-phase high-entropy perovskite oxide ceramic material. The high-entropy ceramic material prepared by the method is simple in preparation process and low in manufacturing cost, the discharge energy storage density can reach 1.48 J/cm<3> by selecting a proper x value, meanwhile, the energy storage efficiency reaches 89.9%, and a new lead-free energy storage material matrix is provided.
