cyclic voltammetry

The electrochemical behavior of carbon-fabric electrodes in the pristine state and after modification with titanium (magnetron sputtering), silver (chemical precipitation) and sequential titanium/silver coatings was studied. The effect of metallic coatings on the conductivity, permittivity, and dielectric losses of model symmetric supercapacitors–fabricated using carbon-fabric electrodes, both with and without the coatings– was investigated.

The work presents a comparative cyclic voltammetry analysis of all-solid-state mock-up cells based on potassium polytitanate. Most measurements were carried out at 25°C. Potassium polytitanate sample with 10 wt.% of phosphotungstic acid was studied at 0°C, followed by the Arrhenius estimate of its characteristics at 25°C. The study focuses on comparing integral capacitive characteristics, response stability at different scan rates and charge storage mechanisms determined using the Dunn and Trasatti methods.
