FILM CAPACITOR Russian patent published in 2018 - IPC H01G4/33 B82B1/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, and more particularly to layered film electrodes for electrolytic capacitors. Film capacitor comprises a multilayer electrode whose base with a developed surface through a adhesive metallizing nanolayer is bonded to the nanoscale coating in the form of at least two layers: functional one of titanium and / or aluminum, which is further enhanced by electrophoresis from a liquid medium, and the second one is a dielectric formed of aluminum and titanium oxides which contains, in the volume and at the boundaries of sections, metal nanoclusters of 0.5–50 nm, doped by means of electrical discharges in the liquid medium, wherein the surface of the dielectric is conformally covered with a layer of electrolyte. Fabric of yarns of carbon or graphene with a porosity of more than 1,000 m²/ g is used as a basis, and the thickness of the functional layer of its coating is developed to 200–250 nm, in the dielectric surface layer, formed by oxidation with formation of intrinsic oxides, clusters of magnetic metals of cobalt, nickel, and iron series are distributed by doping.

EFFECT: invention provides a capacitance of the film capacitor 3–5 times higher than in the known analogs, with a noticeable simplification of manufacturing process without laborious operations of corrugation of the substrate surface with obligatory application of a barrier layer.
