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.

The effect of the structure and the specific surface area of carbon materials, contained in positive electrodes, on the peculiarities of cycling of lithium-sulfur cells (the depth of electrochemical reduction of sulfur and lithium polysulfides, the changes in capacity and Coulomb efficiency of cycling) was studied.

The work is devoted to the study of the electrochemical characteristics of prototype energy storage devices made on the basis of electrodes consisting of titanium-modified graphite woven material “busofit”. It is shown that the modification increases the specific values of the capacitance and the magnitude of the operating voltage.
