Encapsulation of Sn@carbon Nanoparticles in Bamboo-like Hollow Carbon Nanofibers as an Anode Material in Lithium-Based Batteries

Carbon‐coated Sn nanoparticles in carbon nanofibers (see image) were fabricated by pyrolysis of coaxially electrospun nanofibers as an anode material for Li‐ion batteries. The significantly improved electrochemical performance of such an electrode is believed to result from the unique nanostructure consisting of a thin carbon shell around tin nanoparticles, which are further encapsulated in hollow carbon nanofibers.
