Abstrakt: The exploration and advancement of highly efficient anode materials for lithium-ion batteries (LIBs) are critical to meet the growing demands of the energy storage market. In this study, we present an easily scalable synthesis method for the one-pot formation of few-layer MoS 2 nanosheets on a N,S dual-doped carbon monolith with a two-dimensional (2D) architecture, termed MoS 2 /NSCS. Systematic electrochemical measurements demonstrate that MoS 2 /NSCS, when employed as the anode material in LIBs, exhibits a high capacity of 681 mA h g -1 at 0.2 A g -1 even after 110 cycles. The exceptional electrochemical performance of MoS 2 /NSCS can be attributed to its unique porous 2D architecture. The few-layer MoS 2 sheets with a large interlayer distance reduce ion diffusion pathways and enhance ion mobility rates. Additionally, the N,S-doped porous carbon matrix not only preserves structural integrity but also facilitates electronic conductivity. These combined factors contribute to the reversible electrochemical activities observed in MoS 2 /NSCS, highlighting its potential as a promising anode material for high-performance LIBs.
