AP25796271 – Development and study of highly porous electrodes for vanadium flow battery application

Objective of the project – is to obtain porous electrodes with a high specific surface area by the synthesis of titanium dioxide nanotubes (TiNT) and the carbon material (C), with further N-doping for application in vanadium flow batteries.

Relevance: Efficient renewable energy storage is a key challenge today. Vanadium flow batteries are promising, but their low energy efficiency limits their application. This is mainly due to the poor catalytic activity of carbon-based electrodes. Therefore, improvement of electrode materials is required. This study aims to enhance the efficiency of energy storage systems.

Scientific supervisor: Arman Ganidinovich Umirzakov, Master of Natural Sciences, Acting Head of the Laboratory of Electrochemistry and Vanadium Flow Batteries at LLP “Physical-Technical Institute”.

Expected and achieved results: The study identified optimal conditions for the synthesis of TiO₂ nanotubes and confirmed their advanced physicochemical properties. TiNT/C and N-doped composite materials were obtained and experimentally validated as efficient electrode materials. Based on these results, improved electrodes for vanadium flow batteries were developed. These solutions enhance electrochemical activity and improve the overall efficiency of energy storage systems.
