N2 - Ceramics are reliable materials for energy storage and high-power pulse discharge capacitors. However, breakdown electric field (BDS), recoverable energy storage density (Wrec), discharge time (t0.9) become the main constraints. As regards, compositional engineering was adopted to induce relaxation behavior in (Na0.5Bi0.5)0.94Ba0.06TiO3 (NBT-BT) based ceramics by which energy storage performance (ESP) and charge discharge properties (CDP) were significantly improved. (Na0.5Bi0.5)0.94Ba0.06(Ti1−xZrx)O3 (NBBTZ, x = 0, 0.04, 0.08, 0.12, 0.16, 0.20) ceramics are compositional modulation by introducing Zr4+ at B-site. The relaxor ferroelectrics, ESP and CDP of NBBTZ ceramics were significantly improved with the injection of Zr4+. Excellent ESP such as Wrec with 2.83 J cm−3, ultra-high normalized response (ξ) with 134.76 J kV−1 m−2 and maximum polarization (Pmax) of 39.96 μC cm−2 are obtained at 210 kV cm−1. Excellent high-temperature CDP has been excavated simultaneously. Discharge energy density (Wdis), power density (PD) and t0.9 of 0.601 J cm−3, 35.9 MW cm−3 and 83.5 ns were obtained at 100 °C and 100 kV cm−1, respectively. The above results show that NBBTZ ceramics have the ability to become reliable energy storage and pulse power capacitors.
