Paper Title:
Electrochemical Properties of Li-Riched Li[Li0.2Co0.4Mn 0.4]O2 Cathode Material for Lithium Ion Batteries
  Abstract

The Li[Li0.2Co0.4Mn0.4]O2 cathode material was prepared by a sol-gel method. The X-ray diffraction (XRD) spectroscopic showed that the material was a solid solution of LiCoO2 and Li2MnO3. The material showed a reversible discharge capacity of 155.6 mAhg−1 in the voltage window of 2.0-4.3 V after percharge to 4.6 V. While the material cycled in the same voltage window without precharge could only deliver capacity of 77.6 mAhg−1. This high capacity was attributed to the loss of oxygen and structural rearrangement in the precharge process.
