Core–Shell Structure of Hierarchical Quasi‐Hollow MoS 2 Microspheres Encapsulated Porous Carbon as Stable Anode for Li‐Ion Batteries

Monodisperse sulfonated polystyrene (SPS) microspheres are employed as both the template and carbon source to prepare MoS quasi‐hollow microspheres‐encapsulated porous carbon. The synthesis procedure involves the hydrothermal growth of MoS ultrathin nanosheets on the surface of SPS microspheres and... Full description

description: Monodisperse sulfonated polystyrene (SPS) microspheres are employed as both the template and carbon source to prepare MoS quasi‐hollow microspheres‐encapsulated porous carbon. The synthesis procedure involves the hydrothermal growth of MoS 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 shells leaves residual porous carbon in the interior. When being evaluated as the anode materials of Li‐ion batteries, the as‐prepared C@MoS microspheres exhibit excellent cycling stability (95% of capacity retained after 100 cycles) and high rate behavior (560 mAh g at 5 A g). is fabricated using monodisperse sulfonated polystyrene microspheres as both template and carbon source. The as‐prepared C@MoS microspheres exhibit excellent cycling stability (95% of capacity retained after 100 cycles) and high rate behavior (560 mAh g at 5 A g) for application as the anode materials of Li‐ion batteries.
