Abstract: | The anode material cobalt disulfide for lithium-ion batteries was synthesized using the hydrothermal method at a lower temperature. The microstructure and surface morphology of the powders were characterized by means of X-ray diffraction (XRD) and scanning electron microscopy (SEM). Electrochemical tests showed that this sample had superior electrochemical properties. The first discharge capacity is up to 1313.9 mAh/g in the voltage range of 3.00–0.02 V at a current density of 50 mA/g. Adjusting the voltage range to 3.00–0.50 V, the first discharge capacity decreases, but the 20th discharge capacity is 435.5 mAh/g, which is better than what has been reported in the literature. |
