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.

In this review electrochemical and structural data for the electrodes made of certain of perspective materials for supercapacitors are considered. These electrodes were made on the basis of high-dispersed carbon materials.

Behavior of electrodes based on activated carbon P2 (Ener G2) wih additions of plain carbon black, as well as carbon black doped with silver nanoparticles have been studied. Depending on potential range and polarization direction the electrodes were found to reveal a capacitance close to double-layer or pseudocapacitance.
