Extraordinary energy storage performance and thermal stability in sodium niobate-based ceramics modified by the ion disorder and stabilized antiferroelectric orthorhombic R phase
Ruirui Kang,Zepeng Wang,Weijie Yang,Xiaopei Zhu,Peng Shi,Yangfei Gao,Pu Mao,Jiantuo Zhao,Lixue Zhang,Xiaojie Lou +9 more
TL;DR: In this article, a lead-free NN-based energy storage ceramics with ion disorder was presented, where ion disorder is induced in the A-B sites. And the experimental results indicate that the antiferroelectric orthorhombic R phase is stabilized, and the breakdown strength is enhanced due to the decreased grain size after BZS modification, which are conducive to optimizing the energy storage performance.
Journal ArticleDOI

Boyang Zhang,Xiaojie Lou,Kun Zheng,Xuefan Xie,Peng Shi,Mengyao Guo,Xiaopei Zhu,Yangfei Gao,Qida Liu,Ruirui Kang +9 more
TL;DR: In this paper, the electrocaloric effect of BaHf0.2Ti0.8O3-xBa0.94Sm0.04TiO3 (BHT-xBST) ceramics fabricated by the conventional solid-reaction method was studied.
Journal ArticleDOI
Enhanced energy storage properties in lead-free NaNbO3–Sr0.7Bi0.2TiO3–BaSnO3 ternary ceramic
Siyi Li,Peng Shi,Xiaopei Zhu,Bian Yang,Xiaoxiao Zhang,Ruirui Kang,Qida Liu,Yangfei Gao,Haonan Sun,Xiaojie Lou +9 more
TL;DR: In this article, a lead-free 0.10BaSnO3 ceramic with high recoverable energy storage density (Wr 3.51 ǫ J/cm3) and decent energy storage efficiency (η 0.90(0.80NaNbO3)-0.20Sr0.7Bi0.2TiO3)
Journal ArticleDOI
Grain size modulated (Na0.5Bi0.5)0.65Sr0.35TiO3-based ceramics with enhanced energy storage properties
Geoffrey Wheatcroft,Yangfei Gao,Xiaopei Zhu,Bian Yang,Peng Shi,Ruirui Kang,Ye Yuan,Qida Liu,Ming Wu,Jinghui Gao,Xiaojie Lou +10 more
TL;DR: In this paper, a new type of lead-free ceramics (1-x) NBST-xBMS was prepared with the aim of enhancing the breakdown strength (Eb) and reducing the energy storage loss through grain refinement.
Journal ArticleDOI
Remarkably enhanced energy storage properties of lead-free Ba0.53Sr0.47TiO3 thin films capacitors by optimizing bottom electrode thickness
TL;DR: In this article, Ba0.53Sr0.47TiO3 (BST) thin films buffered with La0.67Sr 0.33MnO3 bottom electrode of different thicknesses were fabricated by pulsed laser deposition method on a (001) Sr TiO3 substrate, and it was found that the roughness of electrode decreases and substrate stress relaxes gradually with the increase of LSMO thickness.
