Multifunctional antiferroelectric (Pb0.92−xBa0.05La0.02Dyx)(Zr0.68Sn0.27Ti0.05)O3 multilayer ceramic capacitor (MLCC) was prepared successfully by the tape‐casting method. The MLCC with 10‐thick layers exhibits compact structure, excellent energy‐storage, and strain properties. For energy‐storage performance, the pulsed discharge current reveals that the stored energy can be released in a quite short time of about 600 ns. The maximum discharge energy density was obtained in the sample with x = 0.04 at 300 kV/cm, which was 3.8 J/cm3 calculated by the hysteresis loop and 2.7 J/cm3 by the pulsed discharge current, respectively. Meanwhile, the MLCC possesses large strain property, where the sample with x = 0.04 shows a high field‐induced strain of 0.71% at room temperature. In addition, the temperature dependence of energy‐storage and strain demonstrates that the MLCC has good temperature stability. The results indicate that the multifunctional MLCC can be a promising candidate for the application in energy and sensor fields.
