The dopamine-MoVI complexation-assisted large-scale aqueous synthesis of a single-layer MoS2/carbon sandwich structure for ultrafast, long-life lithium-ion batteries

Single-layer MoS2-carbon nanocomposites (SLMoS2/C) are facilely prepared via a dopamine (DOPA)-Mo-VI complexation-assisted approach. The large interlayer spacing, sandwich structure and crumpled nanosheet morphology of SLMoS2/C render it excellent electrochemical performances as a lithium-ion battery anode, showing a reversible capacity of 500 mA h g(-1) at a discharge rate of 5 A g(-1).
