Deskripsi

In this study, 1T phase MoS<sub>2</sub> nanosheets were synthesized on the surface of a carbon cloth via a hydrothermal reaction. After heat treatment, the 1T phase MoS<sub>2</sub> was transformed into the 2H phase with a better capacity retention performance. As an anode material for lithium-ion batteries, 2H phase MoS<sub>2</sub> on the carbon cloth surface delivers a capacity of 1075 mAh g<sup>−1</sup> at a current density of 0.1 A g<sup>−1</sup> after 50 cycles; while the capacity of the 1T phase MoS<sub>2</sub> on the surface of the carbon cloth without heat treatment fades to 528 mAh g<sup>−1</sup>. The good conductivity of a carbon cloth substrate and the separated MoS<sub>2</sub> nanosheets help to increase the capacity of MoS<sub>2</sub> and decrease its charge transfer resistance and promote the diffusion of lithium ions in the electrode.
