Abstract
A novel layered-material, LiMn0.9Ni0.05Fe0.05O2 with O3-LiCoO2 structure and high electrochemical stability, has been synthesized by an ion exchange method. Specific capacity values of 250 mAh g-1 at C/10 rate and 210 mAh g-1 at C/2 rate have been obtained with little loss in capacity during 30 charge-discharge cycles conducted in the study. The X-ray diffraction and infrared spectroscopy data on the cycled samples suggest that the layered structure in LiMn0.9Ni0.05Fe0.05O2 is preserved after repeated charge-discharge cycles supporting stable specific capacity values. Owing to the high capacity and good stability, LiMn0.9Ni0.05Fe0.05O2 is attractive as a cathode material in Li-ion cells.
