Xiaopei Zhu,Peng Shi,Ruirui Kang,Siyi Li,Zepeng Wang,Wenjing Qiao,Xiaoxiao Zhang,Liqiang He,Qida Liu,Xiaojie Lou +9 more
TL;DR: In this article, a high recoverable energy density of 4.77 J/cm3 with prominent efficiency of 85.7% at 570kV/cm is achieved in Sr0.7Bi0.2TiO3 ceramic.
Journal ArticleDOI
Remarkably enhanced energy-storage density and excellent thermal stability under low electric fields of (Na0.5Bi0.5)TiO3-based ceramics via composition optimization strategy
TL;DR: In this paper, a composition-optimization approach was used to break the long-range ferroelectric order and modulate polar nanoregions (PNRs) in the local structure of (1-x)[0.7(Na0.5Bi0.3(Sr0.2)TiO3]-xBi(Mg 0.5Ti0.4)O3 system.
