Abstract (Na0.5Bi0.5)0.4Sr0.6Ti1-xZrxO3 relaxor ferroelectric ceramic were prepared by a traditional ceramic preparation process introducing Zr4+ at the B-site. It was observed that introducing an appropriate amount of Zr4+ ions into the NBST matrix can improve the energy storage efficiency. (Na0.5Bi0.5)0.4Sr0.6Ti0.5Zr0.5O3 shows excellent energy storage density up to 2.83 J/cm3, and excellent efficiency (83.90 %) at 220 kV/cm. A single layer ceramic capacitor (SLCC) was also prepared by the tape casting technique for multilayer ceramic capacitors (MLCCs) to further enhance the energy storage performance. The recoverable energy storage capacity is increased to 4.52 J/cm3 and the efficiency is 70.02 % at 460 kV/cm. Moreover, it still has a relatively stable energy storage performance after 105 cycles of charge and discharge. This sample has exhibited outstanding energy storage performance, fatigue resistance, and charge/discharge performance and has great potential value in practical applications.
