Preparation of LiMn_(2-x)Cr_xO_4 for Cathode Material of Lithium Ion Battery by Ultrasonic Coordination Precursor Method

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.
