Study on Cobalt-doped LiCoxMn2-xO4 as Cathode Materials for Lithium Ion Battery |
| |
| Abstract: | Cobalt doped LiCoxMn2-xO4 as cathode materials for lithium ion battery were prepared by sol gel method using glycine as chelating agent. The effects of cobalt quantity and sintering temperature on the structure, surface morphology and electrochemical properties of LiCoxMn2-xO4 were investigated by means of XRD, SEM and electrochemical methods. The results showed when x=0.12 and the sintering temperature is 750℃, LiCoxMn2-xO4 display the best electrochemical properties. |
