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.

Kinetic patterns of thin anodic films formation for Ti and Zr in organic mediums are investigated. Influence of solvent nature and polarization is discussed by role surface complex consideration in oxide films growth on this metals.

We studied the electrochemical deposition of lead dioxide on titanium coated with colloidal graphite. It is showing that under optimal process conditions possible to obtain high quality coatings with good adhesion to the base and high-bit characteristics. Received bit characteristics of the layout of the backup power source.

The work is devoted to the study of the influence of the titanium electrodes modofocation in acid and alkali solutions, on electrochemical, dielectric and capacitive characteristics. The paper shows that the film formed on the surface of titanium plates is likely to refer to one of the modifications of potassium titanate. Based on the obtained electrodes, prototype energy storage devices were assembled, which showed a significant increase in capacitance and operating voltage.

The electrochemical behavior of Ti electrode in aqueous solutions containing Na₂MoO₄ + H₃PO₄ + chitosan was investigated by methods of potential – time (E–t) curves at cathodic polarisation in galvanostatic mode, currentless chronopotentiometry, optic microscopy, X­ray spectral analysis of surface and determining roughness by measuring the wetting angle.

Modern technology causes the renewal of the interest to physical and chemical properties of solid oxide electrodes. Among these, PbO₂/substrate has attracted considerable attention due to its application as an electrode in backup current sources. It was shown that the stable and active lead dioxide coating can be produced by appropriate pretreatment of the titanium substrate, including the coating of the substrate with colloidal graphite.

It was established that at the cathodic treatment of titanium in aqueous dimethyl sulfoxide solutions of sodium molybdate, containing phosphoric acid, at the potential of the cathodic incorporation of sodium (E_c  = ? 2.6 V) in the potentiostatic mode, the composition formed on the electrode surface layer depended not only on the composition of the solution, but also on the volume ratio of the aqueous electrolyte solution and the organic solvent (dimethyl sulfoxide).
