(Pb0.97La0.02) (Zr0.5Sr0.5-xTix)O-3 (0.04 < x < 0.10) antiferroelectric (AFE) ceramics were fabricated by the roll forming, and the dielectric properties and high energy-storage performance were investigated in detail. The results showed that all samples had different dielectric behaviors at room temperature. The switching field (E-AF) obviously increased with the increase of Sn, and led to the increase of energy storage. A maximum recoverable energy-storage density of 4.2 J/cm(3) with an efficiency of 82% was achieved in the (Pb0.97La0.02) (Zr0.5Sn0.44Ti0.06)O-3 ceramic at room temperature, and also showed the stable energy-storage behavior. It was also observed that the applied of dc bias field caused the Curie temperature of PLZST move to the lower temperature. The high energy storage density and efficiency indicated that (Pb0.97La0.02) (Zr0.5Sn0.44Ti0.06)O-3 AFE ceramic was a promising material for high-power energy storage. (C) 2015 Elsevier B.V.
