“…Figure 10 exhibits the comparison of energy storage performance (W r and η) between this work and other recently reported NBT-based ceramics. 38,41, Both the samples of x = 0.12 and x = 0.15 have an ultrahigh recoverable energy storage density (4.77 and 4.37 J/cm 3 ) and moderate efficiency (69.0% and 81.4%), which makes them become promising candidates for the electrostatic energy storage technology and pulsed power systems.…”

“…c) Comparison of discharge time of textured ceramics with other lead-based and lead-free ceramics. [5,73,[75][76][77][78][81][82][83][84][85][86][87][88][89][90][91][92][93] inset of Figure 6b. Notably, the textured ceramics behave not only enhanced W d but also the short τ 0.9 at a value of less than 0.1 µs, which is faster than that of random case (≈0.27 µs).…”
