Dielectric capacitors with high energy storage performance are highly desired for advanced power electronic devices and systems. Even though strenuous efforts have been dedicated to closing the gap of density between dielectric electrochemical capacitors/batteries, a single-minded pursuit without near-zero loss ultrahigh efficiency as grantee is in vain. Herein, purpose decoupling inherent conflicts polarization low electric hysteresis (loss), achieving simultaneously multilayer ceramic (MLCCs), we propose an interlaminar strain engineering strategy modulate domain structure manipulate behavior mediums. With heterogeneous layered consisting different antiferroelectric ceramics [(Pb0.9Ba0.04La0.04)(Zr0.65Sn0.3Ti0.05)O3/(Pb0.95Ba0.02La0.02)(Zr0.6Sn0.4)O3/(Pb0.92Ca0.06La0.02)(Zr0.6Sn0.4)0.995O3], our MLCC exhibits giant recoverable 22.0 J cm-3 96.1%. Combined favorable temperature frequency stabilities antifatigue property, this work provides paradigm designing MLCCs high-power conversion
