(Pb,La)(Zr,Sn,Ti)O3 (PLZST) antiferroelectric (AFE) materials have been widely investigated for advanced pulsed power capacitors because of their fast charge-discharge rates and superior energy-storage capacity. For practical applications, pulsed power capacitors require not only large energy density but also high energy efficiency, which are very difficult to achieve simultaneously. To address this problem, we herein investigate the energy-storage properties of PLZST AFE ceramics with a high Sn content by considering that the introduction of Sn can make the polarization versus electric-field (P-E) hysteresis loops slimmer. The results show that an optimum Sn content leads to the realization of both large recoverable energy density (Wre) and high energy efficiency (η) in a single material. With a Sn content of 46%, the PLZST AFE ceramic exhibits the best room-temperature energy storage properties with a Wre value as large as 3.2 J/cm3 and an η value as high as 86.5%. In addition, both its Wre and η vary very slightly in the wide temperature range of 20-120 °C. The high Wre and η values and their good thermal stability make the Pb0.97La0.02(Zr0.50Sn0.46Ti0.04)O3 AFE ceramic a promising material for making pulsed power capacitors usable in various conditions.
