Dielectric materials with high energy storage density ([Formula: see text]) and efficiency ([Formula: see text]) are expected for energy storage capacitors. In this work, [Formula: see text]001[Formula: see text]-textured [Formula: see text][Formula: see text]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 [Formula: see text] of 2.4 J/cm3 and [Formula: see text] 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.
