Abstract


Elektroda na bazi polipirola (PPY) dobijena je na grafitu elektrohemijskom polimerizacijom pirola iz vodenog rastvora koji je sadržavao 0,1 mol dm–3 pirola i 1,0 mol dm–3 HCl. Polimerizacija je ostvarena u galvanostatskim uslovima, gustinom struje od 2 mA cm–2 u trajanju od 1 h. Aktivna masa polipirola je procenjana na 14 mg. Na osnovu galvanostatskih krivih punjenja i pražnjenja (dopovanja i dedopovanja) elektrode na bazi PPY u vodenom rastvoru koji je sadržavao 2,0 mol dm–3 NH4Cl i 1,1 mol dm–3 ZnCl2, dobijenih različitim strujama, odeđena je efikasnost iskorišćenja kapaciteta ove elektrode. Formirana je ćelija u kojoj je elektroda na bazi PPY korišćena kao katoda u kombinaciji sa anodom od cinka i vodenim rastvorom 2,0 mol dm–3 NH4Cl i 1,1 mol dm–3 ZnCl2. Praćen je napon punje­nja/pražnjenja Zn|PPY ćelije različitim strujama, na osnovu čega su procenjeni relevantni električni parametri Zn|PPY ćelije. Na osnovu proračunatih električnih parametara, specifične kapacitivnosti, specifične snage i specifične energije, ispitivana Zn|PPY ćelija se može klasifikovati u kategoriju „superkapabaterija“.
