Nanotubes of bronze titanium dioxide (TiO₂(B)) doped with vanadium were synthesized through hydrothermal reaction. The obtained material possesses mesoporous structure and large specific surface area of 180 m²/g. It was found that the incorporation of vanadium into TiO₂(B) lattice increases the volume of a unit cell. Additionally, the conductivity rose up to three orders of magnitude for doped titanium dioxide reaching the value of 1.70 ? 10 ^{? 8} S/cm.

The effect of ultrasound on the electrodeposition of lead dioxide from lead (II) nitrate on a nickel substrate was studied. It was shown that the highest electrochemical characteristics are observed for the prototypes of backup power sources based on the Pb/HClO₄/PbO₂ system, in which lead dioxide obtained by electrodeposition under the influence of an ultrasonic field on a nickel substrate was used.

Redox flow battery technology has been known since the 1970s. Their low specific characteristics have been of interest for a long time. Practical interest has arisen in recent decades because of the intensive development of alternative energy (such as solar and wind) and the regulation of peak loads in industrial networks.
