Increasing Energy Storage in Activated Carbon based Electrical Double Layer Capacitors through Plasma Processing
Published online by Cambridge University Press: 09 June 2015
Abstract
We present a methodology to enhance the electrical capacitance of activated carbon (AC) electrodes based on the introduction of electrically charged defects through argon plasma processing. Extensive characterization using electrochemical techniques incorporating cyclic voltammetry, constant current charge/discharge, and electrical impedance spectroscopy indicated a close to seven-fold increase in capacitance with respect to untreated AC electrodes, not subject to plasma processing.
