3D Interconnected Porous Graphitic Carbon@MoS2 Anchored on Carbonized Cotton Cloth as an Anode for Enhanced Lithium Storage Performance

Abstract

Developing advanced electrode materials with hierarchical porous structure is one of the promising strategies to achieve superior properties in lithium-ion batteries (LIBs). Herein, this study reports the design and fabrication of MoS2 nanosheets @ 3D interconnected porous graphitic carbon anchored on carbonized cotton cloth (CC/PGC@MoS2) as an anode for LIBs. The uniform interconnected porous PGC@MoS2 is not only grown on the surface of carbon fibers of CC, but also filled in the spaces among carbon fibers to achieve a dense and interconnected conductive network. The intermediate graphitic carbon network in CC/PGC@MoS2 nanostructure can greatly enhance the electronic conductivity, provide short ion transport paths and create abundant active sites. Benefiting from its unique structure, the CC/PGC@MoS2 electrode delivers a high reversible capacity (reversible capacity of 1095.1 mA h g−1 at 0.1 A g−1), excellent rate capability, and remarkable cycling stability (reversible capacity of 816 mA h g−1 at 1.0 A g−1 after 400 cycles), making it promise as an electrode material for LIBs. This study provides a new strategy for designing carbon-based materials with superior electrochemical properties.
