description	The invention provides a sodium bismuth titanate-based ceramic material with low electric field, high energy storage and ultrafast discharge rate and a preparation method thereof, the chemical formula is (Na < 0.5 > Bi < 0.5 >) < 0.94 > Ba < 0.06 > (Ti < 1-x > Zr < x >) O < 3 >, and x is greater than or equal to 0.04 and less than or equal to 0.20. And sintering at 1150-1200 DEG C by controlling the solid solution amount of Zr < 4 + > to obtain the compact sodium bismuth titanate-based ceramic. According to the present invention, the energy storage performance can achieve 2.83 J/cm < 3 > and 73.89% at the room temperature, the current density can achieve 519 A/cm < 2 > at the room temperature under the 100 kV/cm electric field intensity, the power density can achieve 26 MW/cm < 3 >, and the discharge time is as short as 69.8 ns. The sodium bismuth titanate-based energy storage ceramic dielectric material effectively overcomes the defects that a sodium bismuth titanate-based ceramic dielectric material is rela
