Effective Strategy to Achieve Excellent Energy Storage Properties in Lead-Free BaTiO3-Based Bulk Ceramics
Zhonghua Dai,Jinglong Xie,Weiguo Liu,Xi Wang,Lin Zhang,Zhijian Zhou,Jinglei Li,Xiaobing Ren,Xiaobing Ren +8 more
TL;DR: The proposed crossover relaxor ferroelectrics (CRFE) exhibits smaller free energy and lower defect density in modified Landau theory, which benefits to obtain ultra-high energy density and efficiency and a promising candidate to meet the wide requirements for high power applications.
Journal ArticleDOI
Enhanced energy storage properties and stability of Sr(Sc0.5Nb0.5)O3 modified 0.65BaTiO3-0.35Bi0.5Na0.5TiO3 ceramics
TL;DR: In this paper, a crossover relaxor ferroelectrics (CGF) was proposed to obtain higher energy density, energy efficiency, and stability in dielectric ceramics, and a series of lead-free (1-x)-0.9BBNT-0.1SSN ceramic was designed and investigated.
Journal ArticleDOI
A strategy for high performance of energy storage and transparency in KNN-based ferroelectric ceramics
Xiaobing Ren,Zhonghua Dai,Dingyan Li,S. A. Bustani,Zhijian Zhou,Shun Zhou,Weiguo Liu,Jingjing Liu,Xi Wang,Xiaobing Ren,Xiaobing Ren +10 more
TL;DR: In this article, a design strategy is proposed to optimize the energy storage characteristics and transparency of ceramics by introducing nanodomains, increasing the band gap energy and reducing the grain size.
Journal ArticleDOI
Improved energy storage density and efficiency of (1−x)Ba0.85Ca0.15Zr0.1Ti0.9O3-xBiMg2/3Nb1/3O3 lead-free ceramics
Zhonghua Dai,Jinglong Xie,Chen Zhaobing,Shun Zhou,Jingjing Liu,Weiguo Liu,Zengzhe Xi,Xiaobing Ren,Xiaobing Ren +8 more
TL;DR: In this paper, relaxor ferroelectric ceramics are used to enhance energy density and efficiency in the (1−x)Ba0.85Ca0.15Zr0.1Ti0.075BMN ceramic, which the energy density is 26 times as large as that of BCZT ceramic.
Journal ArticleDOI
Domain size engineering in 0.5%MnO2-(K0.5Na0.5)NbO3 lead free piezoelectric crystals
TL;DR: In this paper, the authors investigated the properties of [001]-oriented 0.5%MnO2-(K0.5Na0.3)NbO3 (Mn-KNN) crystals, being poled with different electric fields at 205°C.
