Ion Exchange Method to Synthesis LiMn1-xCoxO2 and Characterization as Cathode Materials for Lithium-Ion Batteries
Layered structure LiMn1-xCoxO2 (0.1≤x≤0.5) cathode materials were prepared by ion exchange method. The samples have an ordered layered structure and well-crystallized. LiMn0.5Co0.5O2 delivered the highest discharge capacity of 175 mAh/g and the charge retention was higher than 95% after 20 cycles. By analysis of the results, as more amount of cobalt is introduced into the LiMn1-xCoxO2 system, the more obvious layered structure and better cycle ability are obtained.
