ÕâÆªÎÄÕÂÎÒ¿´Á˺öà±é£¬µ«ÊǶ¼Ã»ÓÐ˵ÊÇΪʲô£¿The charge storage mechanism is based on surface adsorption
of electrolyte cations C+ (K+, Na+¡­) as well as proton incorporation
according to the reaction:
MnO2 + xC+ + yH+ + (x+y)e¨C ↔ MnOOCxHy (8)
Figure 6 shows a cyclic voltammogram of a single MnO2 electrode in
mild aqueous electrolyte; the fast, reversible successive surface redox
reactions define the behaviour of the voltammogram, whose shape is
close to that of the EDLC. MnO2 micro-powders or micrometre-thick
films show a specific capacitance of about 150 F g¨C1 in neutral aqueous
electrolytes within a voltage window of <1 V.
