Abstract

Abstract:

Cobalt nitrate and hexamethylenetetramine as raw material,Co₃O₄ was prepared through hydrothermal method at different temperature and time.The structure and morphology of the products were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM).The results show that the obtained Co₃O₄ presents different morphologies with different experimental conditions changing.The galvanostatic charge-discharge,cyclic voltammetry (CV) and the electrochemical impedance spectroscopy (EIS) tests showed that Co₃O₄ synthesized at 120 ℃ for 24 h has a high initial discharge capacity which is up to 1 176.8 mAh/g,and it has good stability as well.

Key words: hydrothermal method, Co₃O₄, electrochemical properties, electrode materials
