  • Title: 1T-Phase MoS2 with large layer spacing supported on carbon cloth for high-performance Na+ storage.
    Author: Wang LN, Wu X, Wang FT, Chen X, Xu J, Huang KJ.
    Journal: J Colloid Interface Sci; 2021 Feb 01; 583():579-585. PubMed ID: 33038607.
    Abstract:
    The design and construction of advanced electrode materials is important to the development of high-performance electrochemical energy storage devices. In this paper, V-doped 1T MoS2 nanosheets with a large layer spacing are grown on carbon cloth (CC) via a one-step hydrothermal method. The resulting material features abundant edge sites and active centers, and its large layer spacing facilitates the interlayer shuttle of Na+. Doping with V buffers the volume change and maintains the integrity of MoS2. The layered structure of the composite featuring CC as a conductive substrate effectively prevents the agglomeration of MoS2 during the electrochemical process. When used as an anode material for a Na+ battery, the material displays a high first-cycle irreversible discharge specific capacity of 1234.9 mAh g-1. A specific capacity of 453.2 mAh g-1 is obtained after 100 cycles at a current density of 200 mA g-1. This work provides an effective and eco-friendly route toward obtaining superior MoS2 electrodes for high-performance Na+ storage.
