Enhanced energy storage performance with high temperature stability in ABS-PLZST composites

Polymer capacitors exhibiting high energy storage property at high temperatures is very important to many modern applications. But the energy storage properties of many polymer-based capacitors quickly degrade with rising temperature. This paper designed composite films by combining acrylonitrile-butadiene-styrene (ABS) with various amount of antiferroelectric ceramic fillers ((Pb0.97La0.02) (Zr0.63Sn0.3Ti0.07) O-3), PLZST). The dielectric and energy storage performance were researched from room temperature to 120 degrees C. As a result, a high discharge energy density of 13.92 J/cm(3) and energy efficiency of 83.5 % were achieved under 525 MV/m at 120 degrees C, which are superior those of the state-of-the-art counterparts. The polymer-antiferroelectric composites design could be beneficial for developing high-temperature dielectric capacitors.
