Ceramic dielectric capacitors have gained significant attention due to their ultrahigh power density, current and ultrafast charge-discharge speed. However, potential applications been limited by relatively low energy storage density. Researchers employed various approaches enhance In this study, (1 - x)(Bi0.5Na0.5)0.7Sr0.3TiO3-xCa(Mg1/3Ta2/3)O3 ceramics were prepared via a solid-phase reaction, the effect of structure on properties was investigated. The results indicate that introduction Ca(Mg1/3Ta2/3)O3 significantly alters multiscale structures (Bi0.5Na0.5)0.7Sr0.3TiO3 ceramic, including transformation from T-phase C-phase, refinement ceramic grains, formation polar nanoregions (PNRs), accompanied an increase in bandgap relaxation degree. These structural changes collectively contributed improved overall modified ceramics. Notably, 0.92(Bi0.5Na0.5)0.7Sr0.3TiO3-0.08Ca(Mg1/3Ta2/3)O3 demonstrated recoverable density (Wrec) 8.37 J/cm3 with efficiency (η) 87.7% at electric field 530 kV/cm. It also exhibited good temperature stability (25-120 °C), frequency (1-100 Hz), fatigue (1-105). Furthermore, it displayed exceptional charge discharge properties, (WD), time (t0.9), (CD), (PD) attaining 4.06 J/cm3, 35.2 ns, 2143.28 A/cm2, 460.71 MW/cm3, respectively. findings suggest are promising candidates for high-power pulsed electronic systems.
