Purpose:
For backup memory, solar energy devices, batteries and other power supplies.
Area:
Mechanical engineering, transport industry.
Advantages:
Supercapacitors – energy storage devices – are used along with conventional batteries as power supply. They serve to store large charges, which, if necessary, can be released within a short time, namely in recuperative elements, energy storage-transmission devices, for short-term energy storage in vehicles, etc.
Description:
A technology of composite materials is proposed that combines the advantages of two-dimensional transition metal dichalcogenides and carbon nanostructures. The main attention is paid to the experimental aspects of the synthesis of hierarchical nanostructures with onion- and sandwich-like morphology by the hydrothermal method. Achieving the maximum specific capacity and high cycling values of hybrid supercapacitors is realized through the development and use of electrodes made of nanocomposites based on molybdenum, tungsten and titanium and nanoporous carbon, in which structural, morphological and electrophysical properties are optimally combined.
