Preparation and Electrochemical Energy Storage of NiMoO4@NiMn2O4 Nanocomposites AITranslate
Abstract AITranslate
The NiMoO4@NiMn2O4 composite electrode material based on nickel foam was successfully prepared by two-step hydrothermal method.The phase composition and microstructure of the electrode material were studied by X-ray diffractometer(XRD)and scanning electron microscope(SEM).The electrochemical performance of the electrode material was tested by cyclic voltammetry(CV),galvanostatic charge-discharge(GCD)and electrochemical impedance spectroscopy(EIS).The results show that the velvet-like NiMn2O4is attached to the nanowire-like NiMoO4,which increases the specific surface area and the specific capacitance of the electrode material.At the current density of 1 mA/cm2,the specific capacitances of NiMoO4 and NiMoO4@NiMn2O4 are 240 mF/cm2and 2120 mF/cm2,respectively.Compared with the single NiMoO;electrode material,the NiMoO4@NiMn2O4composite electrode material exhibits more excellent electrochemical performance due to the dual optimization of composition and structure.
