A novel synthesis method,organic solution combustion,was proposed to prepare LiNi0.4Co0.2Mn0.4O2 cathode.XRD experiment revealed that the cathode with α-NaFeO2 layer structure was successfully synthesized.The cathode delivered discharge capacities 140mAh/g(vs Li+/Li)between voltages of 3.0V and 4.3V(vs Li+/Li).And the cathode retained 95%discharge capacity of the initial one at the 20th cycle with cut-off voltage 4.3V(vs Li+/Li).
