Abstract

Pb0.97La0.02(Zr0.65Sn0.3Ti0.05)O3 (PLZST) antiferroelectric ceramics containing various contents of Ba were fabricated via the conventional solid-state reaction approach, in which the dependence of the microstructure, ferroelectric feature, and energy storage performance and its temperature stability were studied in detail. The findings demonstrate that introducing an appropriate content of Ba is able to not only upgrade the electric polarization as well as the recoverable energy density, but also improve the temperature stability of the energy density in PLZST ceramics. Compared to the PLZST without Ba which has a recoverable density around 1.0 J cm-3, the PLZST added with 6 mol. % Ba possesses a favorable recoverable density of 2.4 J cm-3. Furthermore, the introduction of an adequate content of Ba results in a desirable temperature stability of 90% over a 100 °C temperature span. We envisage that the systemically investigation of the recoverable energy density and its temperature stability of the antiferroelectric ceramics in this work will benefit the exploration of a high performance of energy-storage technology for the electric power systems.
