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

Abstract

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.
