A one-step hydrothermal method was employed, using urea (H2NCONH2) as an interlayer modulation agent, to realize the in situ growth of molybdenum disulfide (MoS2) within a three-dimensional conductive network constructed by carbon nanotubes (CNTs). MoS2@CNT composite was prpared and used as anode materials for sodium ion batteries, and theri electrochemical properties investigated. The results indicate that the MoS2@CNT composite materials can effectively alleviate volume expansion during sodium-ion insertion and extraction, thereby improving the sodium storage reaction kinetics and structural stability. Structural characterization results reveal that the incorporation of H2NCONH2 increases the interlayer spacing of MoS2 from 0.62 nm to 0.71 nm, thereby providing additional active sites and shortening ion diffusion pathways. Electrochemical properties test results demonstrate that, after 100 cycles at a current density of 0.1 A/g, the composite maintains a reversible capacity of 387.2 mAh/g, corresponding to a capacity retention rate of 97.5%. Furthermore, after cycling at various current densities, the specific capacity recovers to 402.3 mAh/g, indicating excellent rate capability and superior cycling stability.
