Monodisperse sulfonated polystyrene (SPS) microspheres are employed as both the template and carbon source to prepare MoS 2 quasi‐hollow microspheres‐encapsulated porous carbon. The synthesis procedure involves the hydrothermal growth of MoS 2 ultrathin nanosheets on the surface of SPS microspheres and subsequent annealing to remove SPS core. Incomplete decomposition of SPS during annealing due to the confining effect of MoS 2 shells leaves residual porous carbon in the interior. When being evaluated as the anode materials of Li‐ion batteries, the as‐prepared C@MoS 2 microspheres exhibit excellent cycling stability (95% of capacity retained after 100 cycles) and high rate behavior (560 mAh g −1 at 5 A g −1 ).
