The structural and electrochemical properties of the samples are characterized by means of inductively coupled plasma-atomic emission spectrometer (ICP-AES), X-ray diffraction (XRD), scanning electron microscope (SEM), cyclic voltammogram (CV) and charge-discharge studies. All the samples sintered at different temperatures have a typical layered structure with space group R3-m and good electrochemical performances. The sintering temperature has a remarkable effect on the electrochemical performance of the samples. The sample sintered at 730°C shows the largest initial discharge capacity 191.1mAhg−1 (50mAg−1, 3.0-4.3V) and the best cycling performance. The initial discharge capacity rises to above 200mAhg−1 with the voltage range 3.0-4.5V.
