摘要：

LiNi1/3Mn1/3Co1/3O2 nanofibers as cathode materials for lithium ion batteries were prepared from sol-gel precursor by using electrospun method. The morphology of nanofibers mats was investigated by atomic force microscope (AFM). The results show that the diameter of LiNi1/3Mn1/3Co1/3O2 nanofibers was in the range of 100-300 nm and nanofibers retained the original morphology feature of gel fibers after sintering at high temperature. X-ray diffraction (XRD) and charge-discharge experiments were used to characterize its structure and electrochemical properties. The specific capacity of LiNi1/3Mn1/3Co1/3O2 nanofibers reached 162.82 and 135.18 m Ah g(-1) at 0.2 and 2.0 C, respectively. (C) 2007 Elsevier B.V. All rights reserved.
