Multiple-Stripe Lithiation Mechanism of Individual SnO2 Nanowires in a Flooding Geometry

PRL 106, 248302 (2011)     The atomic scale lithiation mechanism of individual SnO2 nanowires in a flooding geometry was revealed by in situ transmission electron microscopy. The lithiation was initiated by the formation of multiple stripes with a width of a few nanometers parallel to the (020) plane traversing the entire wires, serving as multiple reaction fronts for later stages of lithiation. Inside the stripes, we identified a high density of dislocations and enlarged interplanar spacing, which provided an effective path for lithium ion transport.
