Facile synthesis of electrospun Li(1.2)Ni(0.17)Co(0.17)Mn(0.5)O2 nanofiber and its enhanced high-rate performance for lithium-ion battery applications.

Abstract

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.
