Antiferroelectric (AFE) ceramics exhibit significant potential for diverse applications in pulsed power capacitors, chiefly owing to their electric field-induced AFE-ferroelectric (FE) phase transitions. However, their lower intrinsic breakdown strength (BDS) frequently results in dielectric breakdown prior to the field-induced phase transition, critically undermining their energy storage performance. Herein, we introduced a high-performance PbHfO
