为了研制具有上级储能能力的反铁电介质电容器，反铁电材料必须同时具有大的可恢复能量密度和高的能量效率。基于此，考虑到Sn元素可以使电滞回线变窄，从而提高能量密度和效率，本文设计并制备了高Sn含量的Pb 0. 97 La 0. 02（Zr0.50Sn0.43Ti0.07）O3反铁电陶瓷。实验结果表明，该陶瓷具有3.47 J/cm 3的室温可恢复能量密度和78%的能量效率。此外，在20-120 °C的宽温度范围内，可恢复能量密度和能量效率均显示出上级温度稳定性。Pb0.97La0.02（Zr0.50Sn0.43Ti0.07）O3反铁电陶瓷在较宽温度范围内具有较大的可恢复能量密度和较高的能量效率，是制备适用于各种条件的脉冲功率电容器的理想材料。
To develop antiferroelectric based dielectric capacitors with superior energy storage capacity, antiferroelectric materials must possess simultaneously large recoverable energy density and high energy efficiency. With this motivation, in this work, we design and prepare Pb0.97La0.02(Zr0.50Sn0.43Ti0.07)O3antiferroelectric ceramics with high Sn content considering that Sn element can narrow the electric hysteresis loops and thus improve the energy density and efficiency. The experiment results indicate that a large room-temperature recoverable energy density of 3.47 J/cm3and a high energy efficiency of 78% are realized simultaneously in this kind of ceramic. Besides, in the wide temperature range of 20–120 °C, the recoverable energy density and the energy efficiency both show superior temperature stability. The large recoverable energy density and high energy efficiency in a wide temperature range demonstrate that the Pb0.97La0.02(Zr0.50Sn0.43Ti0.07)O3antiferroelectric ceramic is a good candidate for preparing pulse power capacitors usable in various conditions.
