A simple hydrothermal plus annealing method has been developed to fabricate SnS/NC nanocomposites and their electrochemcial Li-storage performance has also been investigated. The as-prepared composites are characterized by XRD, SEM, EDS, Raman, BET and XPS. In this composite, ultrathin SnS nanosheets are well hybridized with glucosamine-derived nitrogen-doped carbon to form hierarchical porous architectures with large surface areas. Benefiting from the desirable structural merits as well as the generated synergism between components, the SnS/NC composite electrode delivers an enormously enhanced electrochemical lithium-storage performance including large reversible capacity of 832 mAhg(-1) after 100 cycles, enhanced cyclability and superior high-rate capability.
