Journal ArticleDOI
Potassium–sodium niobate based lead-free ceramics: novel electrical energy storage materials
TL;DR: In this article, a hybridization between the Bi 6p and O 2p orbitals was proposed to improve the recoverable energy density (Wrec) of lead-free bulk ceramics.
Journal ArticleDOI

Qingyuan Hu,Ye Tian,Qingshan Zhu,Jihong Bian,Li Jin,Hongliang Du,Denis Alikin,V. Ya. Shur,Yujun Feng,Zhuo Xu,Xiaoyong Wei +10 more
TL;DR: In this article, an effective strategy to achieve ultra-high energy storage performance via nano-scale polarization mismatch and reconstruction is proposed, which can be used to design novel high performance dielectric ceramics for future energy storage devices.
Journal ArticleDOI
Realizing high comprehensive energy storage performance in lead-free bulk ceramics via designing an unmatched temperature range
Zetian Yang,Hongliang Du,Li Jin,Qingyuan Hu,He Wang,Yongfeng Li,Jiafu Wang,Feng Gao,Shaobo Qu +8 more
TL;DR: In this paper, a new strategy was proposed to tailor the temperature region between the temperature corresponding to the maximum dielectric permittivity and the Burns temperature (TB) of relaxor ferroelectrics to room temperature via composition optimization, to explore lead-free bulk ceramics with high comprehensive energy storage properties.
