Abstract
The present invention is directed to a supercapacitor cell having at least one electrode comprising a current collector and an active layer, wherein the active layer comprises activated carbon and high purity carbon nanotubes and is free of binder. The active layer materials are both porous and conductive in order to increase the charge storage capability and to decrease the electrode resistance. In general, the content of carbon nanotubes in the active layer is between 10 and 30 wt. % and the purity of the carbon nanotubes is at least 95 wt. %.
