Abstract
A remarkably high value of specific capacitance of 450 F/g has been observed through electrochemical measurements in the electrode
made of multiferroic Bismuth Ferrite (BFO) in the form of nanorods protruding out. These BFO nanorods were developed on porous
Anodised Alumina (AAO) templates using wet chemical technique. Diameters of nanorods were in the range of 20-100 nm. The high
capacitance is attributed to the nanostructure. The active surface charge has been evaluated electrochemically by cyclic voltammetry (CV)
at different scanning rates and charge-discharge studies. The specific capacitances were constant after several cycles of charge-discharge
leading to their useful application in devices. The mechanism of accumulation of charge on the electrode surface has been studied.
