Abstract:
Electrochemistry deals with the study of electrified interfaces usually involving
electronation and de-electronation reactions, aiding the mutual transformation
of electrical and chemical energies. It encompasses a wide spectrum of
electrochemical processes involving energy storage to conversion devices viz.
batteries, supercapacitors, fuel cells etc.(1) Since, in an electrochemical
transformation, current density (j) is a measure of the rate of the reaction
which in turn is proportional to the number of active sites.(2) Therefore, it is
imperative that porous electrode is expected to show much higher j compared to
planar systeM.S. of similar dimensions on account of its higher number of active
sites aiding in the practical development of such prototypes (Scheme 1).
Therefore porous electrodes are technologically important.
