The cathode material LiMn2-xCrxO4(0≤x≤0.1) was prepared by the ultrasonic coordination precursor method. The synthesized materials were characterized by X-ray diffraction, scanning electron microscope, cyclic voltammetry and charge-discharge testing. The results show that the LiMn2-xCrxO4(0≤x≤0.1) powders have prefect surface morphology, highly discharge capacities and better cycle
performance. In addition, the method can be employed to synthesize cathode
material for lithium-ion battery as a new route.
