摘要：

A new core-shell coaxial carbon nanofibers web (C-CNFW), exhibiting high carbon purity (without any binders), structural integrity, enhanced stability under different current loads, long cycling life, large reversible capacity (over 520 mA h g(-1)), excellent capacity retention and good rate capability, is fabricated by coaxial electrospinning and subsequent carbonization. It is envisaged that the superior electrochemical properties of C-CNFW will make it a promising candidate for the anode material of high-power lithium-ion batteries (LIBs), owing to the unique combinative effects of core carbon material from mineral oil and sheath carbon material from PAN.
