CaO doped 0.5Na[Formula: see text]Bi[Formula: see text]TiO 3 (NBT)-0.5SrTiO 3 (ST) were prepared by a traditional solid-reaction method under various sintering temperatures. X-ray diffraction (XRD), electron scanning microscopy (SEM), and electrical measurements were employed to check the phases, microstructures, and energy storage properties. The doping of CaO can deeply affect the relaxation nature of NBT-ST ceramics. So the energy storage performance could be modified. Specially, sample with 1 at.% CaO exhibits a high energy storage density of 1.51[Formula: see text]J/cm 3 . Any further details can be found within this study.
