Abstract

Abstract: Pb0.97 La0.02 (Zr0.46-x Sn0.54 Tix )O3 (PLZST, x = 0.04, 0.06, 0.08, 0.15, and 0.18) antiferroelectric thick film ceramics were fabricated via a tape-casting approach. The energy storage performance and electrocaloric effect (ECE) were investigated in terms of the measurements on the hysteresis loops and Maxwell relation. The maximum value of energy storage density of 5.2 J/cm 3 and efficiency of 78.2% were procured at 600 kV/cm in Pb0.97 La0.02 (Zr0.42 Sn0.54 Ti0.04 )O3 thick film ceramics at room temperature. In addition, the ECE was indirectly calculated using the Maxwell relation and the polarizations extracted from the P-E loops as a function of temperature and electric field, an adiabatic temperature change of Δ T = 2.47 °C was procured in Pb0.97 La0.02 (Zr0.42 Sn0.54 Ti0.04 )O3 thick film ceramics at 500 kV/cm, corresponding to the calculated electrocaloric strength of 0.48 K(MV/m) −1 . These results indicate that the PLZST thick film ceramics are promising for practical applications in high-power energy storage capacitors and solid-state refrigeration devices.
