Abstract

LiNi1-3Co1-3Mn1-3O2 and Ce-doped LiNi1-3Co1-3Mn1-3O2 cathode materials were synthesized by a co-precipitation method and solid phase synthesis and characterized using X-ray diffraction XRD and scanning electron microscopy SEM.
The results indicated that the resultant cathode materials with different Ce content all had a good layer structure and high crystallinity.
Electrochemical performance testing of the cathode materials showed that the discharge capacity increased with increasing Ce content while the initial reversible capacity attenuation decreased with Ce doping.
When the Ce content of the cathode materials is x=0.2, and the current charge and discharge rate is a constant 0.2 C, the discharge capacity maintained 91% of its initial capacity after cycling 50 times.
