Structure and morphology of molybdenum disulfide (MoS 2 ) play an important role in improving its reversible lithium storage and sodium storage as anodes. In this study, a facile method is developed to prepare C/C@SnO 2 /MoS 2 nanofibers with MoS 2 nanoflakes anchoring on the core–shell C/C@SnO 2 nanofibers through hydrothermal reaction. By adjusting the concentration of MoS 2 precursors, the synthesized MoS 2 with different slabs dimensions, size, and morphologies are obtained, constituting budding and blooming wintersweet branch‐like composite structure, respectively. Owing to scattered MoS 2 nanoparticles and sporadic MoS 2 nanoflakes, the budding wintersweet branch‐like composite nanofibers processes less slabs of staking in number and large specific surface area. Benefiting from the exposed C@SnO 2 shell layer, the synergistic effect among SnO 2 , carbon, and MoS 2 is strengthened, which maximizes the advantage of each material to exhibit stable specific capacities of 650 and 230 mAh g −1 for Li‐ion batteries and Na‐ion batteries after 200 cycles.
