AB  - Electrochemical oxidative polymerization at constant current density was used to produce polypyrrole (PPY) at graphite electrode from aqueous acidic electrolyte containing 0,1 mol dm-3 pyrrole and 1,0 mol dm-3 HCl. PPY electrode was than used as cathode while zinc electrode served as anode in electrochemical cell with an aqueous electrolyte containing 2,0 mol dm-3 NH4Cl and 1,1 mol dm-3 ZnCl2. The relevant electrochemical parameters of this cell were evaluated from electrochemical experiments. It was observed that charge of Zn|PPY cell started at voltage between 0,5 and 0,7 V and proceeded up to 1,5 V. Charge/discharge of the cell was dependent on charge/discharge current density with open circuit voltage of the fully discharged cell around 1,3 V. The estimated values of specific energy were between 46 and 68 W h kg-1 while specific power values were between 125 and 380 W kg-1, which suggested that Zn|PPY cell had “supercapaterry” behavior.
AB  - Elektroda na bazi polipirola (PPY) dobijena je elektrohemijskom oksidativnom polimerizacijom na grafitnoj elektrodi u uslovima konstantne gustine struje. Kao elektrolit za sintezu, korišćen je vodeni rastvor 0,1 mol dm-3 pirola i 1,0 mol dm-3 HCl. Formirana je elektrohemijska ćelija u kojoj je elektroda na bazi PPY korišćena kao katoda dok je anoda bila elektroda od cinka, a elektrolit se sastojao od vodenog rastvora 2,0 mol dm-3 NH4Cl i 1,1 mol dm-3 ZnCl2. Procena relevantnih elektrohemijskih i električnih parametara ove ćelije bazirana je na elektrohemijskim eksperimentima. Utvrđeno je da je proces punjenja/pražnjenja zavisio od struje punjenja/pražnjenja, punejnje ćelije započinje na naponu između 0,5 i 0,7 V, a završava se na naponu od oko 1,3 V. Procenjene vrednosti energije bile su između 46 i 68 W h kg-1, dok se za specifičnu snagu dobijaju vrednosti između 125 i 380 W kg-1, što ukazuje na superkapabaterijska svojstva Zn|PPY ćelije.

AB  - The electrochemically synthesized polypyrrole (PPy) is investigated as a possible active material of the low-cost aqueous based secondary power sources in combination with zinc, lead oxide, and lead sulfate. The discharge capacity of the polypyrrole in the chloride-based electrolyte (for the Zn|PPy cell) is in the range 110 mAh g −1 of PPy, while in the sulfate-based electrolyte ∼150 mAh g −1 of PPy (for the PbSO 4 |PPy and PPy|PbO 2 cells), which is close to the theoretically calculated values. Electrochemical and electrical parameters, reactions in the cells, specific capacity, specific capacitance, energy, and power, for the Zn|PPy, PPy|PbO 2 and PbSO 4 |PPy cells are determined. In addition, the energy efficiency, for the considered systems is estimated. Obtained values of the specific power and energy, could classified investigated systems as a battery type hybrid superacapacitors or “supercapattery”. © 2019 Elsevier B.V.

AB  - The copper sulfide is successfully deposited onto electrochemically formed polypyrrole, by successive ion-adsorption and reaction (SILAR) processes. The photoelectrochemical behavior of the polypyrrole, copper sulfide and copper sulfide modified polypyrrole are investigated in the sulfide based solution, under cathodic and anodic polarization. The improvement of the photooxidation stability, as well as activity of copper sulfide modified polypyrrole is achieved. Such behavior is explained by recombination of electrons from Cu2-xS conducting band with the holes of the PPy LUMO. © 2015 Elsevier B.V. All rights reserved.
