The present disclosure provides a coiled capacitor comprising a coil formed by a flexible multilayered tape, and a first terminating electrode and a second terminating electrode which are located on butts of the coil. The flexible multilayered tape contains the following sequence of layers: first metal layer, a layer of a plastic, second metal layer, a layer of energy storage material. The first metal layer forms ohmic contact with the first terminating electrode and the second metal layer forms ohmic contact with the second terminating electrode. The energy storage material comprises material selected from the list comprising rylene fragments, doped oligoaniline and p-oligo-phenylene, supramolecular structures, colloidal composite with dispersion (suspension) of electro-conductive anisometric particles in an insulator matrix, material comprises a surfactant.
