Abstract: Addressing the escalating demand for high-performance lithium-ion batteries (LIBs) in light of the energy crisis and environmental concerns, this study aimed to develop an advanced anode material. To overcome the limitations of conventional graphite anodes, a novel NG@MoS 2 @LS-C composite was synthesized via a hydrothermal method combined with lignin–carbon coating and carbonization. Specifically, MoS 2 nanoparticles were uniformly deposited on the surface of natural graphite, followed by lignin–carbon coating and carbonization, resulting in a unique structure with enhanced electrochemical properties. The experimental results show that the incorporation of MoS 2 nanoparticles significantly improved cycling performance, while the lignin–carbon coating mitigated volume expansion, enhancing cycle stability. The composite exhibited an initial capacity of 588.2 mAh·g⁻¹ and retained a reversible capacity of 326.2 mAh·g⁻¹ after 30 cycles, outperforming pristine graphite. In addition, the lamellar structure of MoS 2 nanoparticles, combined with the buffering and electrolyte blocking effects of a lignin-derived carbon shell, endows the composite with low charge transfer resistance and a high lithium-ion diffusion rate, resulting in excellent electron-ion cooperative transmission characteristics. This study presents a promising anode material for next-generation LIBs, which can contribute towards green and sustainable energy storage solutions.
