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@MoS2@LS-C composite was synthesized via a hydrothermal method combined with lignin–carbon coating and carbonization. Specifically, MoS2 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 MoS2 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 MoS2 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.
