FLAT THIN SUPERCAPACITOR WITH LOW RESISTANCE AND METHOD OF ITS MANUFACTURE Russian patent published in 2023 - IPC H01G11/34 H01G11/86 H01G9/145 

FIELD: electrical engineering.

SUBSTANCE: flat ultra-thin supercapacitor, which can be used in various fields of industry as a miniature low-current power source with stored energy. A method for manufacturing a flat supercapacitor based on a carbon-carbon nanocomposite has also been proposed. The effect is achieved due to the fact that the flat supercapacitor is made of a porous carbon material with a specific surface area of 1,400-1,600 m² on the base and a conductive activated carbon nanocomposite obtained by coating carbon particles with a layer of graphite-like carbon 1-3 nm in size by pyrolysis at 900°C in water vapor, which is mixed until a homogeneous paste is obtained, in which the ratio of the components of the porous carbon material, carbon nanocomposite, and binder is 10:9:1.

EFFECT: reducing the equivalent series resistance to 35 mOhm and increasing the capacitance to 160 mF.
