N2 - Based on the significant advantages of dielectric ceramics in high power energy storage, (1-x) (0.55Bi0.5Na0.5TiO3-0.45Sr0.7Nd0.2TiO3)-xAgNbO3 (NBSNT-xAN) ceramics were prepared by traditional solid phase method. The introduction of AN in NBSNT ceramics not only increased the degree of relaxation, but also refined the grain size, enhanced the BDS, and finally improved the energy storage performance. It is found that the NBSNT-0.5AN ceramics obtained an effective energy storage density as high as 3.08 J/cm3 and an efficiency of 79.94%. In addition, good thermal stability and temperature stability were exhibited in the range of 30–120 °C and 10–350 Hz, and at the same time, it performed very well in the pulsed test at room temperature and variable temperatures. This provides a design idea for the miniaturization and integration of energy storage ceramic materials.
