The invention relates to the field of electrochemical capacitors and, in particular, electrochemical supercapacitorsUnconventional internal design yields a larger capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. per unit volume than other types. Valuable for high-current and low frequencyThe number of complete cycles or vibrations per unit of time. Rate of alternation in an AC current. Expressed in cycles per second or hertz (Hz). electrical circuits, power supply filters, etc. Applications are similar to those of rechargeable batteries.. More specifically, the invention is directed towards the production of an electrochemical supercapacitor with an electric double layer, in which the energy accumulators and electrodes consist exclusively of materials based on various forms of carbon.
The carbon supercapacitor comprises: a hermetic housing; substrate electrodes made from a carbon-containing material and provided with discrete, highly porous accumulation layers; separators made from a porous dielectricThe insulating material between the plates of the capacitor. The material is chosen for its ability to permit electrostatic attraction and repulsion to take place across it. The material will have the property that energy required to establish an electric field is recoverable in whole or in part, as electric energy. In other words, a good dielectric material is a poor conductor of electricity while being an effective supporter of electrostatic fields. material in the form of a film, which separate the substrate electrodes; current collectors for the above-mentioned discrete, highly porous accumulation layers; and also external switching electrodes in the form of strips. The substrate electrodeA solid electric conductor through which an electric current enters or leaves in a medium accumulation layers, the separators, the electric current collectors and the switching electrodes are made from carbon material and/or carbon-containing material.
