MnO2/PPy电极存储的电荷由表面吸脱附理论和体相内氧化还原反应两种

MnO2 / PPy electrode by the charge stored in the body surface and the desorption phase theory redox reaction of two mechanisms to achieve interaction, the contribution rate is closely related to the current density. (C) seen from FIG. 9, as the current density increases, resulting in reduced electrode capacity ratio, because the current density is gradually increased time to cause diffusion of electrolyte ions into the active phase, when the stored charge is mainly suction surface provided by the desorption mechanism.

The charge stored by MnO2/PPy electrode is realized by the combination of surface absorption theory and internal redox reaction, and the contribution rate is closely related to current density. Figure 9(c) can be seen, with the increasing current density, the electrode ratio capacity will decrease, because the current density gradually increased resulting in electrolyte ions to diffuse to the active substance phase, at this time the stored charge is mainly provided by the surface absorption mechanism.

The charge stored in MnO2 / PPy electrode is realized by two mechanisms of surface adsorption desorption theory and oxidation-reduction reaction in bulk phase. The contribution rate is closely related to the current density. It can be seen from Fig. 9 (c) that the specific capacity of the electrode decreases with the increase of current density, which is because the electrolyte ions do not diffuse into the active material phase, and the stored charge is mainly provided by the surface adsorption desorption mechanism.<br>
