High-entropy and phase engineering towards excellent energy storage performance in lead-free Bi0.5Na0.5TiO3-based ceramics under moderate electric fields

While the high-entropy (HE) strategy has enabled lead-free dielectric ceramics to achieve ultra-high energy storage performance (ESP) under extreme electric fields ( E > 500 kV/cm), their ESP at moderate field fields (200 kV/cm ≤ E ≤ 500 kV/cm) remains restricted by the trade-off...

Unraveling phase evolution and polarization anomaly driven by chemical strain in BNT-based energy storage ceramics

Abstract Chemical substitution in ferroelectric ceramics is widely used to tune phase stability and electromechanical response; however, the role of substitution-induced chemical strain on polarization and structural stability remains insufficiently understood. Herein, we report...
