摘要：
High-entropy perovskite oxides in (Bi0.4Na0.2K0.2Ba0.2)TiO3- Sr(Mg1/3Nb2/3)O3 system were designed and pre-pared for dielectric energy storage. The effects of composition and sintering temperature on energy storage performance were investigated. The temperature-and frequency-dependent energy storage performance was characterized. A ceramic with a recoverable energy storage density of 3.37 J/cm3 and an energy storage effi-ciency of 80 % was obtained at 310 kV/cm. The energy density is one of the best ever reported at low electric fields. The current result provides an idea for developing high-entropy dielectric energy storage ceramics.
