The advancement of sodium-ion batteries (SIBs) depends on designing high-performance anode materials. Hard carbon (HC) is a suitable candidate due to the availability and low cost of resources for production, but its limited reversible capacity and unsafeness upon high-rate charging remain obstacles. Herein, a novel simple strategy combining low-temperature pyrolysis and hydrothermal treatment for the fabrication of a synergistic composite based on hard carbon coated by molybdenum disulfide nanosheets has been developed. The MoS2@HC composite shows superior electrochemical characteristics for SIBs in contrast with HC and MoS2 on their own. In particular, it demonstrates almost two times better sodium storage ability at high current densities as compared to HC. The operating potential of the MoS2@HC composite is higher than that of HC, implying improved battery safety. At the same time, the composite shows a better cycle life than MoS2. It stays stable during long-term cycling, whereas MoS2 shows unacceptable behavior already after the 100th cycle. The resulting MoS2@HC composite at low current density of 20 mA g–1 delivers a reversible capacity stabilized at 304 mAh g–1. It also demonstrates cycling stability at high current densities with a capacity of 131 mAh g–1 over 200 cycles at 1000 mA g–1. This research opens a facile way for designing hard carbon based anode for sodium-ion batteries with increased capacity and improved safety.
