摘要:
A low-temperature reaction route is introduced based on hydroxide precipitation method to synthesize the cathode material LiNi 1/3Co1/3Mn1/3O2. The crystal structure and morphology of the prepared powder have been characterized by X-ray diffraction and Scan electron microscope, respectively. The charge-discharge tests were performed between 2.5 and 4.5 V. The discharge capacity of the material is strongly impacted by the reaction temperature. The powders sintered at 850 °C show the best electrochemical performance and the initial discharge capacity is about 160 mAh g-1 at 5 C. Powder X-ray...
