A Flexible Solid Composite Electrolyte with Vertically Aligned and Connected Ion-Conducting Nanoparticles for Lithium Batteries.
TL;DR: The vertically aligned and connected Li1+xAlxTi2-x(PO4)3 (LATP) NPs in the poly(ethylene oxide) (PEO) matrix to maximize the ionic conduction, while maintaining the flexibility of the composite.
Journal ArticleDOI

Xue Wang,Xue Wang,Haowei Zhai,Boyu Qie,Qian Cheng,Aijun Li,James Borovilas,Bingqing Xu,Changmin Shi,Tianwei Jin,Xiangbiao Liao,Yibin Li,Xiaodong He,Shanyi Du,Yanke Fu,Martin Dontigny,Karim Zaghib,Yuan Yang +17 more
TL;DR: Li et al. as mentioned in this paper used a vertically aligned ceramic/polymer composite electrolyte composed of high ionic conductivity Li 1.5Al0.5Ge1.5(PO4)3 and polyethylene oxide (PEO) polymer.
Journal ArticleDOI
Direct Observation of Dynamic Symmetry Breaking above Room Temperature in Methylammonium Lead Iodide Perovskite
Alexander N. Beecher,Octavi E. Semonin,Jonathan M. Skelton,Jarvist M. Frost,Maxwell W. Terban,Haowei Zhai,Ahmet Alatas,Jonathan S. Owen,Aron Walsh,Simon J. L. Billinge,Simon J. L. Billinge +10 more
TL;DR: In this paper, the authors measured phonon dispersions in CH3NH3PbI3 and found direct evidence for another form of disorder in single crystals: large-amplitude anharmonic zone edge rotational instabilities of the PbI6 octahedra that persist to room temperature and above.
Journal ArticleDOI
Stabilizing Solid Electrolyte-Anode Interface in Li-Metal Batteries by Boron Nitride-Based Nanocomposite Coating
Qian Cheng,Aijun Li,Aijun Li,Na Li,Shuang Li,Amirali Zangiabadi,Tai-De Li,Wenlong Huang,Alex Ceng Li,Tianwei Jin,Qingquan Song,Weiheng Xu,Nan Ni,Haowei Zhai,Martin Dontigny,Karim Zaghib,Xiuyun Chuan,Dong Su,Kai Yan,Yuan Yang +19 more
TL;DR: Li et al. as mentioned in this paper utilized a chemically inert and mechanically robust boron nitride (BN) film as the interfacial protection to preclude the reduction of Li1.3Al0.3Ti1.7(PO4)3 (LATP) solid electrolyte by Li, which is validated by in situ transmission electron microscopy.
Journal ArticleDOI
PVDF/Palygorskite Nanowire Composite Electrolyte for 4 V Rechargeable Lithium Batteries with High Energy Density
Pengcheng Yao,Bin Zhu,Bin Zhu,Haowei Zhai,Xiangbiao Liao,Yuxiang Zhu,Weiheng Xu,Qian Cheng,Charles Jayyosi,Zheng Li,Jia Zhu,Kristin M. Myers,Xi Chen,Yuan Yang +13 more
TL;DR: This work prepares poly(vinylidene fluoride) polymer electrolytes with an organic plasticizer, which possesses compatibility with 4 V cathode and high ionic conductivity and introduces palygorskite nanowires as a new ceramic filler to form composite solid electrolytes (CPE), which greatly enhances both stiffness and toughness of PVDF-based polymer electrolyte.
