摘要：

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. © 2009 Wiley-VCH Verlag GmbH & Co.
