Preparing MoS2‐based materials with reasonable structure and catalytic activity to enhance the sluggish kinetics of lithium polysulfides (LiPSs) conversion is of great significance for Li–S batteries (LSBs) but still remain a challenge. Hence, hollow nanotubes composed of N‐doped ultrathin MoS2 nanosheets (N‐MoS2 NHTs) are fabricated as efficient S hosts for LSBs by using CdS nanorods as a sacrifice template. Characterization and theoretical results show that the template effectively inhibits the excessive growth of MoS2 sheets, and N doping expands the interlayer spacing and modulates the electronic structure, thus accelerating the mass/electron transfer and enhancing the LiPSs adsorption and transformation. Benefiting from the merits, the N‐MoS2 NHTs@S cathode exhibits an excellent initial capacity of 887.8 mAh g−1 and stable cycling performances with capacity fading of only 0.0436% per cycle at 1.0 C (500 cycles). Moreover, even at high S loading that of 7.5 mg cm−2, the N‐MoS2 NHTs@S cathode also presents initial excellent areal capacity of 7.80 mAh cm−2 at 0.2 C. This study offers feasible guidance for designing advanced MoS2‐based cathode materials in LSBs.
