“…However, for a fuller description of electrochemical systems the evolution of impedance spectra should be investigated during the evolution of the system in both potential and time. With the progress of digital techniques this is becoming increasingly possible [ 15 – 17 ].…”

Electrochemical systems with high capacities demand devices for electrochemical impedance spectroscopy (EIS) with ultra-low frequencies (in order of mHz), that are almost impossible to accomplish with analogue techniques, but this becomes possible by using a computer technique and accompanying digital equipment. Recently, an original software and hardware for electrochemical measurements, intended for electrochemical systems exhibiting high capacities, such as supercapacitors, has been developed. One of the included methods is EIS. In this paper, the method of calculation of circuit parameters from an EIS curve is described. The results of testing on a physical model of an electrochemical system, constructed of known elements (including a 1.6 F capacitor) in a defined arrangement, proved the validity of the system and the method.

\\ и. Бр. A2.9f\G KONDENZATORI VRLO VELIКE КAPACITIVNOSTI NA BAZI SULFIDA ВАКRА Izvod Ova disertac1ja predstavlja doprinos razvoju superkondenzatora novog tipa zasnovanog na prirodnim sulfid1ma bakra. Ispitivanje superkondenzatora (zbog velikih kapacitivnosti, odnosno vremenskih konstanti) zahteva znatnu modifikaciju i prilagodavanje klasicnih elektrohemijskih metoda i instrumentalne tehnike. U okviru disertacije uradena је matematicka analiza kojom su definisani parametri ekspeпmentalnih metoda, kako sedam modifikovanih standardnih, tako i dve nove Dirakove naponske i nagiЬne strujne. Hardver i softver nephodan za njihovu real1zaciju predstavlja znacajan deo ove disertacije. Metode su najpre proverene na posebno konstruisanom fizickom modelu elektricnom kolu sa komercijalnim superkondenzatorom od 1,5F, kao i simulacijom na racunaru. Sve metode su primenjene pri razvoju novog tipa superkondenzatora na bazi prirodnih minerala bakra kovelina (CuS) i halkozina (Cu 2 S). Maksimalna dobiJena kapacitivnost na halkozinu bila Је oko 1 OOF/cm 2 Na kraju је realizovan i ispitan protip superkondenzatora sa halkozinom kao aktivnim elektrodnim materijalom.
