FIELD: electricity.
SUBSTANCE: invention refers to electric engineering and can be applied in mobile communication devices as a reusable DC source. Proposed supercapacitor is made in the form of thing film structure including electrodes separated by solid electrolyte film, where zirconium dioxide stabilised by yttrium is selected as solid electrolyte, graphene nanoparticles comprise one electrode, and second electrode is made of conductive polymer, polypyrrol.
EFFECT: increased specific energy of capacitor.
