Preparation of electrode, used in supercapacitor, comprises mixing a carbonated pulverizing material and a solvent, adding a binding polymer, drying the mixture, optionally mixing the mixture and recovering the collector

摘要

Preparation of an electrode (A) (having an active carbon base and carbon nanotubes on a collector) comprises mixing a carbonated pulverizing material (I) and a solvent, adding a binding polymer and mixing till homogenization, drying the mixture, optionally mixing the mixture and recovering the collector. Independent claims are also included for: (a) preparation of the mixture having an active coal base and carbon nanotubes; (b) (A) with improved lifespan; and (c) supercapacitor comprising (A).
