Electrochemical Characteristics of Lithium Transition-Metal Oxide as an Anode Material in a Lithium Secondary Battery
Doh CH, Jin BS, Lim JH, Moon SI
Lithium transition-metal oxides (LiTMOs) such as LiCoO2 and LiMn2O4 were investigated for their use as anode material for the lithium secondary battery. Ni|Li(0)|LiPF6(1M, EC + DEC (1 : 1))|LiTMO|Cu cell was fabricated and its electrochemical properties were examined. LiCoO2 and LiMn2O4 showed fairly good characteristics as anode material as well as cathode material. At the 1st cathodic process, LiCoO2 had a potential plateau at 1.4 V on open circuit potential line, but LiMn2O4 had two ambiguous potential plateaus between 0.6 and 0.1 V. The specific resistance of Li|LiCoO2 cell was 8 ohm·g, but that of Li|LiMn2O4 cell decreased gradually while the reaction proceeded. The specific capacities of Li|LiCoO2 and Li|LiMn2O4 cells at the 1st discharge were about 300 mAh/g. Capacity retention of Li|LiMn2O4 cell during charge-discharge cycling was higher than that of Li|LiCoO2 cell.
