Electrochemical characteristics of polyoxometalate/polypyrrole/carbon cloth electrode synthesized by electrochemical deposition method

초록

In this report, polyoxometalte (POM)-doped polypyrrole (Ppy) was deposited on surface of three-dimensional carbon cloth (CC) using an electrodeposition method and its pseudocapacitive behavior was investigated using cyclic voltammetry and galvanostatic charge-discharge. The POM-Ppy coating was thin and conformal which can be controlled by electrodeposition time. As-prepared POM-Ppy/CC was characterized using scanning electron microscope and energy-dispersive X-ray spectroscopy. The unique 3D nanocomposite structure of POM-Ppy/CC was capable of delivering excellent charge storage performances: a high areal capacitance (561 mF/cm2), a high rate capability (85%), and a good cycling performance (97% retention). © 2016 The Korean Society of Industrial and Engineering Chemistry.
