Journal ArticleDOI
Fracture toughness of graphene
Peng Zhang,Lulu Ma,Feifei Fan,Zhi Zeng,Cheng Peng,Phillip E. Loya,Zheng Liu,Zheng Liu,Yongji Gong,Jiangnan Zhang,Xingxiang Zhang,Pulickel M. Ajayan,Ting Zhu,Jun Lou +13 more
TL;DR: The combined experiment and modelling verify the applicability of the classic Griffith theory of brittle fracture to graphene and quantifies the essential fracture properties of graphene and provides mechanistic insights into the mechanical failure of graphene.
Journal ArticleDOI
In situ atomic-scale imaging of electrochemical lithiation in silicon
Xiao Hua Liu,Jiangwei Wang,Shan Huang,Feifei Fan,Xu Huang,Yang Liu,Sergiy Krylyuk,Sergiy Krylyuk,Jinkyoung Yoo,Shadi A. Dayeh,Albert V. Davydov,Scott X. Mao,Scott X. Mao,S. Tom Picraux,Sulin Zhang,Ju Li,Ting Zhu,Jian Yu Huang +17 more
TL;DR: It is shown that in situ transmission electron microscopy can be used to study the dynamic lithiation process of single-crystal silicon with atomic resolution and observe a sharp interface between the crystalline silicon and an amorphous Li(x)Si alloy.
Journal ArticleDOI
Two-phase electrochemical lithiation in amorphous silicon
Jiangwei Wang,Yu He,Feifei Fan,Xiao Hua Liu,Shuman Xia,Yang Liu,C. Thomas Harris,Hong Li,Jian Yu Huang,Scott X. Mao,Ting Zhu +10 more
TL;DR: The two-phase lithiation can be the fundamental mechanism underpinning the anomalous morphological change of microfabricated a-Si electrodes, i.e., from a disk shape to a dome shape, which is critical to the development of microstructurally stable electrodes for high-performance lithium-ion batteries.
Journal ArticleDOI
In situ transmission electron microscopy study of electrochemical sodiation and potassiation of carbon nanofibers.
Ying Liu,Feifei Fan,Jiangwei Wang,Yang Liu,Hailong Chen,Katherine L. Jungjohann,Yunhua Xu,Yujie Zhu,David I. Bigio,Ting Zhu,Chunsheng Wang +10 more
TL;DR: In situ TEM experiments reveal the mechanical degradation of CNFs through formation of longitudinal cracks near the c-C/d-C interface during sodiation and potassiation, shedding light onto the development of carbon-based electrodes for NIBs and KIBs.
Journal ArticleDOI
Self-limiting lithiation in silicon nanowires.
TL;DR: In this article, the rate of growth of a surface layer of amorphous LixSi in crystalline Si nanowires during the first lithiation was measured using in situ transmission electron microscopy, which is attributed to the retardation effect of the lithiation-induced stress.
