Enhancement in electrochemical behavior of copper doped MnO2 electrode
چکیده انگلیسی
In the present work, we report a simple chemical precipitation method for the preparation of different levels of Cu doped MnO2 nanocrystals. X-ray diffraction, field emission transmission electron microscope and X-ray photoelectron spectroscopy were used to study the material properties. To demonstrate the suitability of the doped products for electrode applications electrochemical properties were evaluated by Cyclic Voltammetry (CV), galvanostatic charge-discharge studies and impedance spectroscopy. The results indicate that the MnO2 electrode modified with 0.1 M of Cu has a better electrode property with a specific capacitance of 583 F/g and an energy density of 80 W h kg−1.
