Optimizing the performance of ion-transfer and energy store via hexagonally ordered alumina nanopore template based electrode

摘要

In order to establish enhanced electrochemical performance, the electrochemical properties of nanopore structures should be considered. Electrochemical properties such as charge density and ion transfer can characterize the performance of electrochemical reaction for energy storages, double layer capacitors, etc. Using the Cottrell equation and the Randles-Sevcik equation, it is possible to estimate the electrochemical property of a target material. These typical models are useful to predict and comprehend the electrochemical property. However, there is still lack of understanding of essential factor for electrochemical properties of nanopored structures. The electrochemical performances of the nickel-based hexagonally ordered nanopore electrode (NE) was investigated by various pore diameters in this research. This study has revealed the critical parameter that can affect to electrochemical property of the NE.
