The Li1.2Ni0.17Co0.17Mn0.5O2 nanofibers were synthesized by a simple electrospinning process. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) showed that electrospun nanofibers with small particle size of 10–30 nm were formed. It was found that the electrospinning process leads to the formation of an effective conducting nanofiber, which provides improved intercalation kinetics. The eletrospun Li1.2Ni0.17Co0.17Mn0.5O2 nanofibers showed a high discharge capacity of 256 mA h g–1 during the first cycle. In particular, the electrospun Li1.2Ni0.17Co0.17Mn0.5O2 nanofiber sample exhibited excellent rate capability when compared to the co-precipitated Li1.2Ni0.17Co0.17Mn0.5O2 particle sample.
