Abstract High‐entropy perovskite ceramics have garnered widespread attention in the energy storage field due to their diversified composition and superior performance. However, preparation of high‐performance high‐entropy ceramic materials still faces many challenges complex structure. This work systematically studies effects MgO, SiO 2 , Li CO 3 MnCO on sintering temperature performance (Na 0.2 Bi Ba Sr Ca )TiO (NBBSCT) ceramics. The introduction successfully reduced 1150°C achieved a high efficiency 95.5% with this composition. NBBSCT 0.5 wt%MgO exhibited breakdown 300 kV/cm an density 3.7 J/cm . study indicates that adding appropriate aids can significantly improve behavior method provides new insights into enhancement
