An innovative approach for efficient synthesis of petal-like molybdenum disulfide nanosheets inside hollow mesoporous carbon spheres (HMCSs), the yolk–shell structured MoS2@C, has been developed. HMCSs effectively control and confine in situ growth of MoS2 nanosheets and significantly improve the conductivity and structural stability of the hybrid material. The yolk–shell structured MoS2@C is proven to achieve high reversible capacity (993 mA h g–1 at 1 A g–1 after 200 cycles), superior rate capability (595 mA h g–1 at a current density of 10 A g–1), and excellent cycle performance (962 mA h g–1 at 1 A g–1 after 1000 cycles and 624 mA h g–1 at 5 A g–1 after 400 cycles) when evaluated as an anode material for lithium-ion batteries. This superior performance is attributed to the yolk–shell structure with conductive mesoporous carbon as the shell and the stack of two-dimensional MoS2 nanosheets as the yolk.
