摘要：

Free-standing carbon nanofibres (CNFs) are prepared by the carbonization of poly-acrylonitrile using a simple electro-spinning technique. The electro-spun fibres are studied as an anode material for lithium-ion batteries in half-cell configurations. The fibres showed an initial discharge capacity of 826 mAh g(-1) at a current density of 200 mA g(-1) and exhibited an appreciable capacity profile during cycling. The Li-storage mechanism has been explained based on the cyclic voltametric and galvanostatic cycling results.
