Antiferroelectric (AFE) materials demonstrate potential application in pulse power systems and energy-storage devices due to outstanding density (PD) rapid charge-discharge capability. Simultaneously achieving a high discharge energy (Wdis) large AFE ceramics remains key research focus. In this work, method for optimizing parameters is proposed ameliorating the grain size of ceramic enhancing antiferroelectricity, ultimately breakdown strength (Eb). Therefore, an excellent recoverable (Wrec) 13.6 J/cm3 efficiency (η) 82% along with thermal frequency stabilities are simultaneously achieved (Pb0.96La0.02Ca0.02)(Hf0.9Sn0.1)O3 (C1) at maximum electric field. The multistage field-induced phase transition phenomenon detected polarization-electric field (P-E) hysteresis loop C1 ceramic. Meanwhile, superior PD 314.6 MW/cm3 Wdis 9.05 as well time (84 ns) also obtained 380 kV/cm. results highlight (Pb0.98-xLa0.02Cax)(Hf0.9Sn0.1)O3 pulsed applications.
