超级电容材料La掺杂NiCo-LDH的研究

In this paper, La-doped NiCo-LDH electrode materials were prepared by hydrothermal method. The composition and structure of the materials were characterized by electron scanning electron microscopy (SEM), X-ray diffraction (XRD) and infrared spectroscopy (FTIR). The electrochemical test results such as cyclic voltammetry (CV), galvanostatic charge discharge measurement (GCD) and electrochemical impedance spectroscopy (EIS) show that the doping of La can affect the electrochemical performance of NiCo-LDH and improve the charge discharge capacity of the material. When the doping amount of La is 4%, NiCo-LDH has the highest specific discharge capacity.
