Abstract

Dielectric materials with high energy storage density (

W_{rec}

) and efficiency (

η

) are expected for energy storage capacitors. In this work,

NbO₃ (NBN) ceramics were prepared by a templated grain growth technique. The effects of microstructure and orientation degree on dielectric properties, polarization and energy storage performance were investigated. The textured ceramic with an optimized orientation degree (70%) showed a high

W_{rec}

of 2.4 J/cm³ and

η

of 85.6%. The excellent energy storage properties of textured ceramic originate from the co-effect of interfacial polarization and clamping effect. The results indicate that texture development is a potential candidate to optimize the energy storage properties of functional ceramics.
