Lead-free antiferroelectric AgNbO3 ceramics have garnered extensive attention due to their rapid charge/discharge capabilities and environmentally friendly nature, holding immense potential for energy storage applications. However, the practical utilization of has been hindered by its low density. This study employed an A/B-site co-doping strategy, which yielded positive effects on performance ceramics. By modifying A/B-sites with equivalent amounts Bi3+ Y3+ ions, enhanced maximum...
Abstract Antiferroelectrics with excellent energy storage density have attracted considerable attention due to their potential applications in electric vehicles, pulsed power weapons, etc. With the trend of environmental protection, lead-free antiferroelectric AgNbO 3 is a promising candidate for applications. However, limited recoverable ( W rec ) severely restricts its application high-power systems. To enhance , A/B-site Sm 3+ /Hf 4+ co-doping approach was adopted. It positively...
Ion displacements are the cause of ferroelectricity in perovskites. By properly shifting ions, ab initio computations have been extensively used to investigate properties perovsites various structural phases. In addition relatively simple ion displacements, perovskites another type distortion known as antiferrodistortion or oxygen octahedron tilting. The interplay between these two types distortions generated abundant phases that can be tedious prepare for computation, especially large...
High specific capacitance, rapid charge–discharge kinetics, good cycle stability, scalability, and synthetic control are just a few of the many advantages that Co 3 O 4 nanoflowers provide as electrode materials for supercapacitors. Based on aforementioned outstanding capabilities, attractive options range energy storage uses, such grid-level storage, electric cars, portable devices, renewable systems. Herein, an exhibit electrochemical supercapacitance 700 F/g at 15 A/g, with exceptional...
Abstract In this work we report experimental evidence for the weak high-temperature ferromagnetism in Bi 1− x R FeO 3 ( = Dy, Y) compounds by systematic characterizations, excluding possible side-effects from other iron-based impurities. Remarkable saturated magnetic moment was observed Y-substituted samples, Y , which is larger than obtained Dy Dy-substituted samples with antiferromagnetic background. The physical origin of ferromagnetic transition discussed and serious lattice distortions...
