Abstract
The pristine Li1.20[Mn0.52Ni0.20Co0.08]O2 and Ce3+-doped Li1.20[Mn0.50Ni0.20Co0.08Ce0.02]O2 cathode materials have been synthesized by using the typical sol-gel method. The XRD, SEM, ICP-OES and galvanostatic charge-discharge tests were carried out to study the influence of Ce3+ doping on the crystal structural, morphology and electrochemical properties of Li1.20Mn0.54Ni0.13Co0.13O2. The XRD result revealed the Ce3+ doping modification could decrease the cation mixing degree. The galvanostatic charge-discharge tests results showed that the sample after Ce3+ doping demonstrated the smaller irreversible capacity loss, more stable cyclic performance and better rate capacity than those of the pristine one.
