In this article, the saturation kinetics model that describes chronoamperometric response of PPy(DBS) in our recently published work is extended to study the effect of mass and charge density on the step response of PPy(DBS). The saturation kinetics model is based on a mechanistic approach for charge storage in conducting polymers and leads to the development of structure-dependent input-output relationships to develop a cation concentration sensor. In this article, we demonstrate the use of poles and residues in the saturation kinetics model to deconstruct the chronoamperometric and chronocoulometric response by seperating the contributions from double layer charge accumulation and faradaic ion transport. We show that: (i) the number of redox sites, and therefore the number of ingressing ions at saturation, is directly proportional to the mass of the conducting polymer, (ii) the accessibility of these redox sites associated with ion ingress is inversely proportional to the conducting polymer charge density, (iii) the rate of ion ingress is found to be inversely proportional to mass and charge density, due to the decrease in the driving force per unit redox site and redox site accessibility, respectively. For lower charge densities, the mass has a dominant effect on saturation and rate of ion ingress, with charge density effects becoming apparent as it increases. The saturation charges obtained are consistent with the peak charges during cyclic voltammetry, thus validating the mechanistic interpretations. The findings of this article highlight the trade-offs between charge storage and transport properties for conducting polymer devices.

In this work, the use of nanostructured conducting polymer deposits on energy-storing devices is described. The cathode and the anode are electrochemically modified with nanowires of polypyrrole and poly(3,4-ethylenedioxythiophene), respectively, prepared after the use of a mesoporous silica template. The effect of aqueous or ionic liquid medium is assayed during battery characterization studies. The nanostructured device greatly surpasses the performance of the bulk configuration in terms of specific capacity, energy, and power. Moreover, compared with devices found in the literature with similar designs, the nanostructured device prepared here shows better battery characteristics, including cyclability. Finally, considering the semi-conducting properties of the components, the device was adapted to the design of a solar-rechargeable device by the inclusion of a titanium oxide layer and cis-bis(isothiocyanate)-bis(2,2′-bipyridyl-4,4′-dicarboxylate) ruthenium (II) dye. The device proved that the nanostructured design is also appropriate for the implementation of solar-rechargeable battery, although its performance still requires further optimization.
