A method for forming electrode structured microsystems based on titanium foil was developed. These microsystems can be used in electrochemical energy storage devices. The method includes a three-stage chemical treatment of the titanium foil surface: etching in concentrated HCl to create a microrelief, processing in the aqueous solution of KOH to form a layer of potassium polytitanate and the subsequent modification in the solution of manganese sulfate with the following heat treatment at 750°C.

The new materials obtained in the potassium polytitanate (PPT)–MnSO₄ system by modifying PPT in aqueous solutions of manganese sulfate of various concentrations, followed by thermal treatment and annealing at 1080°C, were synthesized and studied. The phase composition of the obtained materials was determined. Their electrochemical and electrophysical properties in the temperature range from 250 to 700°C were studied.
