Optimizing the energy storage performance of NaNbO₃ ceramics by rare-earth-based composite perovskite Sm(Mg_0.5Zr_0.5)O₃ modification

Abstract

Researchers often improve the energy storage performance of NaNbO₃ ceramics through doping with Bi-based composites. Recent studies have shown that rare-earth elements, such as La and Sm, can suppress remanent polarization. In this study, a (1-x)NaNbO_3-xSm(Mg_0.5Zr_0.5)O₃ ceramic system was designed. Doping with Sm(Mg_0.5Zr_0.5)O₃ (SMZ) increases the resistance, activation energy, and bandgap of NaNbO₃ ceramics, improves the breakdown field strength, and optimizes the energy storage efficiency of NaNbO₃ ceramics. In this study, 0.92NaNbO₃-0.08 SMZ achieved an energy storage density of 4.3/cm³ and an energy storage efficiency of 85.6% at 560 kV/cm. When x = 0.15, the sample exhibited an ultrahigh breakdown field strength and energy storage efficiency (720 kV/cm and 91%, respectively). In addition, the 0.08 SMZ sample had an ultrafast release rate of t_0.9(57 ns), high current density (777.1 A/cm²), and high power density (69.93 MW/cm³). It has practical application prospects in high-performance energy storage capacitors.
