(Top). Schematic of the experimental setup. (Bottom) Structural and phase characterization of one SnO2 nanowire anode during charging at −3.5 V against the LiCoO2 cathode. (a) TEM image of the nanowire containing a reaction front (dislocation cloud) that separates the reacted (amorphous) and nonreacted (single-crystal SnO2) areas. (b–e) EDP taken from different sections of the nanowire. (f) High-resolution transmission electron microscopy (HRTEM) image from a charged nanowire, showing that Sn nanoparticles are dispersed in an amorphous matrix. Reproduced with permission.43
