About the project

The growing demand for electricity requires the exploration of electrical devices, which could meet the increasing needs of modern society. The supercapacitors are group of devices with promising opportunities for storage of large amounts of energy. Among the intensively studied groups of compounds are transition metal oxides, sulphides, nitrides and their composites with carbon nanomaterials. Recently, the large scientific interest is focused on the synthesis of these composites. However, the electrochemical capacitance of transition metal compounds(oxides, sulphides, nitrides)/carbon nanomaterials as electrode material are much higher than the capacitance of conventionally used activated carbon.
The aim of the DesignHyCap project is synthesis of transition metal compounds/carbon nanostructure composites as an electrode material for hybrid capacitor. The project will consist of several steps, including synthesis of transition metal compounds/carbon nanomaterials under various conditions, its physical characterization and evaluation of their capacitance properties in supercapacitor working in aqueous electrolyte. The composites with carbon nanostructures will be synthesized by facile chemical precipitation, but also by hydrothermal and solvothermal treatment. The compounds ratio in the composite will be verified by the electrochemical measurements. Finally, the chosen composites will be tested in hybrid capacitor using aqueous solution as an electrolyte, where at least one electrode will be built of transition metal nitride/carbon nanomaterial composite. Materials received as the project may contribute to setting new trends in the development of innovative energy storage devices.
