METHOD OF CURRENT PICKUP FOIL MANUFACTURING AND CURRENT PICKUP FOIL FOR SUPERCAPACITORS Russian patent published in 2014 - IPC H01G11/28 

FIELD: electricity.

SUBSTANCE: method of current pickup foil manufacturing involves sequential two-stage application of catalyst substance and vertical developed carbon columnar nanostructure in the form of bundles of separate divided fibres gathered along aluminium substrate surface onto both sides of aluminium capacitor foil by physical deposition from magnetronic hydrogen discharge plasma. This carbon nanostructure grows from catalyst sublayer and serves as buffer layer at the border between pickup plate and surface of porous graphite electrode of supercapacitor, thus ensuring contact impedance reduction and significant decrease in supercapacitor weight and cost.

EFFECT: enhanced power of supercapacitor due to reduced parasitic contact impedance at the border of electrode and pickup contact.
