Ruthenium Oxide: Thin Film and Electrochemical Properties
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 8
Abstract
Electrochemical supercapacitors have attracted increased interest due to their high power density and long life cycle compared to batteries and high energy density compared to conventional capacitors. In recent years various metal oxides have involved attention for use as electrochemical capacitors in high power applications. In particular Ruthenium Oxide offer the advantage of providing higher energy density and electrochemical stability compared to carbon and polymer materials. Here Ruthenium oxide thin films have been deposited on stainless steel substrate by sol-gel spin coating method. Thin film properties of deposited samples were studied by XRD ,SEM, FTIR,EDAX. Thin films were used as electrodes for supercapacitor with 0.1 M KOH electrolyte. It showed maximum capacitance of 581 F/g for 4 coats at spin rate of 5 mv/sec. Also stability of the electrode was calculated. Power density and energy density were determined from galvanostatic charge-discharge analysis.
