Tailoring polar nanoregion dynamics via defect dipole and Nb5+ substitution for high-performance lead-free energy storage SrTiO3-based ceramics

Puntos clave

• Enhanced energy storage capacity is achieved through controlled polar nanoregion dynamics.
• Defect dipole and Nb5+ substitution significantly influence the ceramic properties at a molecular level.
• Assessment using advanced characterization techniques shows a strong correlation between defects and performance metrics.
• Further studies are needed to explore long-term durability in practical applications and scaling up.
