Such anisotropic expansion is attributed to the interfacial processes of accommodating large volumetric strains at the lithiation reaction front that depend sensitively on the crystallographic orientation. This anisotropic swelling results in lithiated Si nanowires with a remarkable dumbbell-shaped cross section, which develops due to plastic flow and an ensuing necking instability that is induced by the tensile hoop stress buildup in the lithiated shell. The plasticity-driven morphological instabilities often lead to fracture in lithiated nanowires, now captured in video. These results provide important insight into the battery degradation mechanisms.}}, Publisher = {{AMER CHEMICAL SOC}}, Address = {{1155 16TH ST, NW, WASHINGTON, DC 20036 USA}}, Type = {{Article}}, Language = {{English}}, Affiliation = {{Zhu, T (Reprint Author), Georgia Inst Technol, George W Woodruff Sch Mech Engn, Atlanta, GA 30332 USA.
