THIN-FILM TECHNOLOGY FOR THE CREATION OF PROMISING ELECTRODE MATERIALS FOR HYBRID CAPACITORS

This work is devoted to the development of a thin-film technology for manufacturing a promising electrode material based on a highly porous carbon matrix. The paper presents the developed design of an electrode material based on a highly porous carbon material for energy storage devices with a double electric layer and for hybrid capacitors in which energy is accumulated both in a double electric layer and due to electrochemical reactions. It is shown that the developed thin-film technology is very promising for the purpose of increasing energy intensity in contrast to the traditional thick-film technology, and also allows you to create capacitor cells with parameters exceeding the parameters of existing supercapacitors (ionistors). The prospect of using the developed electrode material design and thin-film technology for hybrid capacitors with a specific energy consumption of over 300 Wh/kg is also shown.
