NOVELTY - The supercapacitor electrodes include electrodes that are separated by a solid electrolyte film layer. A solid electrolyte applied zirconia stabilized with yttria. One of the electrodes is made of nanoparticles graphene. The graphite is distributed in phase-transitional material with a low coefficient of thermal expansion, and the solid electrolyte comprises carbon nanotubes. USE - Supercapacitor electrodes with graphene and a modified heat accumulating material.
