Abstract

Abstract: The pristine Li1.20 [Mn0.52 Ni0.20 Co0.08 ]O2 and Ce 3+ -doped Li1.20 [Mn0.50 Ni0.20 Co0.08 Ce0.02 ]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 Ce 3+ doping on the crystal structural, morphology and electrochemical properties of Li1.20 Mn0.54 Ni0.13 Co0.13 O2 . The XRD result revealed the Ce 3+ doping modification could decrease the cation mixing degree. The galvanostatic charge-discharge tests results showed that the sample after Ce 3+ doping demonstrated the smaller irreversible capacity loss, more stable cyclic performance and better rate capacity than those of the pristine one.
