core satellite batio3 srtio3 assemblies for a local compositionally graded relaxor ferroelectric capacitor with enhanced Energy storage density and High Energy Efficiency
Journal of Materials Chemistry C, 2015Co-Authors: Xiaohui Wang, Huiling Gong, Yanan Hao, Zhengbo ShenAbstract:Dielectric capacitors with High Energy density and low Energy loss are of great importance in High power electric and electronic systems. Traditional BaTiO3 (BT) or its solid solutions have been widely explored as High Energy density materials owing to their notably High dielectric constants. However, these materials often suffer from significant drawbacks of strong dielectric nonlinearity, low breakdown strength and High hysteresis loss, limiting the Energy storage density and Energy utilization Efficiency. In this study, by using core-satellite structured nanocubic SrTiO3 (ST) decorated BT assemblies, a composite capacitor with enhanced breakdown strength and weaker dielectric nonlinearity was successfully fabricated in contrast with the pure ferroelectric BT ceramic, resulting in elevated Energy storage density and High Energy Efficiency as extracted from the polarization-electric field loops. The mechanism behind the improved electric and dielectric performances was discovered to be the remarkable suppression of grain size owing to the existence of the ST nanocubes and also the ferroelectric relaxor behaviors arising from the local compositionally graded structure due to the controlled sintering and modulated diffusion of Sr. This work provided a new approach for fabrication of dielectric materials with promising High Energy density and low loss.

Achieving High Energy Efficiency and Energy density in PbHfO3-based antiferroelectric ceramics
Journal of Materials Chemistry C, 2020Co-Authors: Wenna Chao, Tongqing YangAbstract:Antiferroelectric materials with Higher electric field, reduced Energy dissipation and lower remanent polarization generally display excellent Energy storage performance. In this work, Pb0.98La0.02(HfxSn1−x)0.995O3 lead-based antiferroelectric ceramics were synthesized by a rolling process. It is revealed that the inhomogeneous distribution of Sn4+ can disorder the local structure, which is responsible for the slim hysteresis loops. Superior Energy storage performance (recoverable Energy density Wrec = 7.63 J cm−3, η = 94% at an electric field of 380 kV cm−1) with excellent thermal stability (20–120 °C) were achieved in Pb0.98La0.02(Hf0.45Sn0.55)0.995O3 ceramic. In addition, it also shows a notable discharge current density of 1430 A cm−2 and High level of power density of 193 MW cm−3 with a fast discharge speed (112 ns discharge period), which greatly promote the application of this series of component materials in Energy storage applications.
