Item Coaxial MoS2@Carbon Hybrid Fibers: A Low-Cost Anode Material for High-Performance Li-Ion Batteries(MDPI AG, 2017-02-13) Zhou, Rui; Wang, Jian-Gan; Liu, Hongzhen; Liu, Huanyan; Jin, Dandan; Liu, Xingrui; Shen, Chao; Xie, Keyu; Wei, Bingqing; Rui Zhou, Jian-GanWang, Hongzhen Liu, Huanyan Liu, Dandan Jin, Xingrui Liu, Chao Shen, Keyu Xie and Bingqing Wei; Wei, BingqingA 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 uniform growth 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 carbon makes the MoS2@carbon composites low-cost and promising anode materials for high-performance Li-ion batteries.
