exhibited remarkable temperature stability and fatigue resistance. The energy storage density only decreased
5
by 11% from room temperature to 140 °C, and after 10 electrical cycles, the energy storage density
decreased by only 5.2%. Overall, these findings suggest that 0.91BNBT-0.09SBTZ ceramics have great
potential as dielectric materials for energy-storage dielectric capacitors.
