Abstract
- Energy storage efficiency (η) and large recoverable energy density (W<subscript>re</subscript>) are necessary for antiferroelectric materials in order to develop antiferroelectric-based dielectric capacitors with exceptional energy storage capacity. In the present paper, the effect of doping La<superscript>3+</superscript> on the energy storage capacity of Pb<subscript>1−x</subscript>La<subscript>x</subscript>(Hf<subscript>0.45</subscript>Sn<subscript>0.55</subscript>)<subscript>0.995</subscript>O<subscript>3</subscript> antiferroelectric ceramics was studied. Adjusting the content of La and changing the phase structure of PLHS from antiferroelectric to relaxor ferroelectric gradually, which narrowed its hysteresis loop, yielded a high energy storage efficiency of 81.9% and the maximum breakdown field strength of 200 kV/cm when x = 2 mol%. In addition, the recoverable energy density and energy storage efficiency both showed excellent temperature stability and frequency stability in the temperature range of 10–110 °C and the frequency range of 10–100 Hz, suggesting that Pb<subscript>0.98</subscript>La<subscript>0.02</subscript>(Hf<subscript>0.45</subscript>Sn<subscript>0.55</subscript>)<subscript>0.995</subscript>O<subscript>3</subscript> are favorable materials candidates for the preparation of pulsed-power capacitors that can be used in a wide range of conditions.
