In this study, we investigated the outcome of SrTiO3 (ST) doping on the performance of energy storage of Bi0.5 Na0.5 TiO3 (BNT)based ceramics. A 0.8BNT–0.2ST composition was synthesized via the conventional solid-state route and characterized for structural, microstructural, and dielectric properties. X-ray diffraction confirmed the formation of a single-phase P4bm perovskite structure, and FESEM analyses showed a noticeable reduction in grain size with 20wt% ST doping. A reduction in the dielectric constant was observed, along with a downward shift in the phase transition temperature. Consequently, an obvious improvement in recoverable energy density (Wrec ) and efficiency (η) had been noticed from ferroelectric results, reflecting enhanced relaxor characteristics in the doped specimen. Overall, SrTiO3 addition was found to be an effective strategy for boosting the energy storage capability of BNT ceramics.
