| Abstract: | Ferroelectric materials are gaining considerable attention for energy storage, electrocaloric and pyroelectric energy harvesting applications. In particular, Ba0.85Ca0.15Zr0.10Ti0.90O3 (BCZT) and BaTi0.89Sn0.11O3 (BTSn) ceramics are among the best-studied lead-free BaTiO3-based ferroelectrics with high piezoelectric and electrocaloric properties. In this work, we prepared a 0.6BCZT–0.4BTSn solid solution. The structural, energy storage, electrocaloric, and pyroelectric properties are investigated. An energy density of 61.4 mJ cm-3 with a high energy efficiency of 82.4 % at 90 °C is achieved. The electrocaloric temperature change, which is determined indirectly via the Maxwell relation, is 0.5 K at 86 °C and 25 kV cm-1. It is stable over a wide temperature range of around 65 °C and has a coefficient of performance of 15. Moreover, a pyroelectric energy density of 124.1 mJ cm-3 is achieved. The results of this study show that the 0.6BCZT–0.4BTSn ceramics is a multifunctional material with energy storage, electrocaloric and pyroelectric properties. |
