ABSTRACT:
A metal tape is employed to form electrodes for an electrolytic capacitor. At least one side surface of the metal tape has rigidly adhered thereto a separating sheet of microporous thermoplastic material. This preferably is done by a thermal process or by cementing. Both surfaces of the metal tape, for example formed of aluminum, may have separating sheets applied thereto. Selected regions of such surface or surfaces may be maintained uncoated, whereby subsequent use as electrodes may enable the attachment to such uncoated regions of terminal contacts.
