AI summary

A supercapacitor consisting of a tight protective housing, first and second electrodes, which are electrically insulated from each other. One or both electrodes are also insulated from the housing. Free volume of the cell and the space between the electrodes are filled with electrolyte fluid. On the surface of the first electrode there are applied carbonaceous materials comprising C-14 isotope. Method of supercapacitor construction lies in the preparation of the first and second electrodes with application of the surface layer made of carbonaceous materials, allocation of the first and second electrodes inside the tight housing and their electric insulation from each other, filling of the housing with electrolyte fluid. Into the layer of carbonaceous materials onto the surface of the first electrode the C-14 isotope is introduced.
