Pore engineered carbons for enhanced electrochemical performance

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.
