MoS2 nanosheets uniformly coated TiO2 nanowire arrays with enhanced electrochemical performances for lithium-ion batteries

摘要

Three-dimensional heterogeneous nanocomposites exhibit eminent cycling stability and rate capability as electrode materials for lithium-ion batteries. In this work, the composites of MoS2 nanosheets uniformly coated TiO2 nanowire arrays are fabricated by a glucose-assisted hydrothermal approach. The usage of glucose can be favorable to the uniform growth of MoS2 morphology. As anode materials for lithium ion batteries, the composites exhibit good specific capacity, cycling stability and rate capacity. The enhanced electrochemical properties are attributed to uniformity of composites since the uniform composites can effectively integrate the good cycling stability of TiO2 nanowire arrays and high capacity of MoS2 nanosheets. The gentle synthesis procedure and excellent electrochemical properties make TiO2 nanowire@MoS2 nanosheet arrays promising in high-performance lithium-ion batteries. (C) 2018 Elsevier B.V.
