| Abstract: | Layered LiNixMn1-xO2 as cathode material for lithium-ion battery was prepared by the process of high temperature solid reaction && ion exchange. The electrochemical properties at different charge-discharge voltages and the XRD analysis of the material were investigated. The results show that the capacity is about 160 mAh/g during the discharging from 4.3 V to 2.5 V, and it is about 180 mAh/g during the discharging 4.3 V to 2.0 V, or is more than 225 mAh/g when it is discharged from 4.3 V to 1.0 V. The material has not significant structure transformation to the spinel-type phase on cycling. |
