Fast Energy Storage of SnS₂ Anode Nanoconfined in Hollow Porous Carbon Nanofibers for Lithium-Ion Batteries.

ABSTRACT: The development of conversion-typed anodes with ultrafast charging and large energy storage is quite challenging due to the sluggish ions/electrons transfer kinetics in bulk materials and fracture of the active materials. Herein, the design of porous carbon nanofibers/SnS₂ composite (SnS₂ @N-HPCNFs) for high-rate energy storage, where the ultrathin SnS₂ nanosheets are nanoconfined in N-doped carbon nanofibers with tunable void spaces, is reported. The highly interconnected carbon nanofibers in three-dimensional (3D) architecture provide a fast electron transfer pathway and alleviate the volume expansion of SnS₂ , while their hierarchical porous structure facilitates rapid ion diffusion. Specifically, the anode delivers a remarkable specific capac
