Abstract

The invention provides an improved double-layer capacitor in which the improvement is a planar layered electrode assembly which has low electrical resistance and which has high electric storage capacity. The electrode material is produced by a process in which acicular electrically-conductive particles are blended with a binder, oriented by extrusion, and cut to form planar electrode discs or plates in which the acicular particles are oriented as nearly perpendicular as possible to the flat surfaces of the electrode.
