On the Enhancement of Energy Storage Performance in Modified Relaxor Ferroelectric Ceramics for Pulsed Power Applications
Relaxor-type ferroelectrics show important potential in energy storage fields due to their significantly enhanced energy performance and good temperature stability compared to normal ferroelectrics. Here, a novel, high-performance ternary composition, (0.4−x)BiFeO<sub>3</sub>-xBi(Mg<s...

| description | Relaxor-type ferroelectrics show important potential in energy storage fields due to their significantly enhanced energy performance and good temperature stability compared to normal ferroelectrics. Here, a novel, high-performance ternary composition, (0.4−x)BiFeO<sub>3</sub>-xBi(Mg<sub>1/2</sub>Ti<sub>1/2</sub>)O<sub>3</sub>–0.6BaTiO<sub>3</sub> (x = 0.2, 0.25, 0.3, 0.35, 0.4), was designed by compositional modulation, which displays typical relaxor characteristics. The optimum energy storage properties can be attained at x = 0.35, accompanied by energy efficiency of 84.87%, a promising energy storage density of 2.3 J/cm<sup>3</sup> and good temperature stability of less than 10% over 20–160 °C. Moreover, the samples provide stable cycling fatigue after 10<sup>5</sup> cycles and a fast discharge time of <i>t</i><sub>0.9</sub> < 0.1 μs, indicative of promising applications in energy units. |
