EDLCs tend to store relatively larger charges. The total charge (q) stored in
the double-layer capacitor is proportional to its potential (V) with its capaci-
tance (C) as proportionality constant; that is qαV or q = C × V. Accordingly,
V = q/C. The charge and discharge reactions on the activated carbon anode
and its potential can be expressed as follows:
