Abstract
A low-cost bio-mass-derived carbon substrate has been employed to synthesize MoS2@carbon composites through a hydrothermal method. Carbon fibers derived from natural cotton provide a three-dimensional and open framework for the uniformgrowth of MoS2 nanosheets, thus hierarchically constructing coaxial architecture. The unique structure could synergistically benefit fast Li-ion and electron transport from the conductive carbon scaffold and porous MoS2 nanostructures. As a result, the MoS2@carbon composites-when serving as anodes for Li-ion batteries-exhibit a high reversible specific capacity of 820 mAh·g-1, high-rate capability (457 mAh·g-1 at 2 A·g-1), and excellent cycling stability. The use of bio-mass-derived carbonmakes the MoS2@carbon composites low-cost and promising anode materials for high-performance Li-ion batteries.
