Abstract : We report on the self-supported, two-dimensional (2D) SnS nanosheets electrode directly grown on
metallic current collectors via non-catalytic and template-free, vapor transport synthetic route. The
self-supported SnS nanosheets electrode demonstrates good cycling performance and superior rate capabilities:
a capacity of 380 mAh g1 even at 20C rate (after charging for 3 min), larger than the theoretical
capacity of the carbon-based electrodes currently used in commercial Li ion batteries. The origin of such
an improvement in the long-term cycle stability and electronic/ionic transport kinetics, is understood by
means of various microscopic investigation as well as unique characteristics of self-supported nanostructuring
strategy itself.
