The electrode (10) includes an electrically conductive surface (14) with a galvanic pellicle, or carbon nanotube mat (18), secured to the conductive surface (14). The pellicle (18) has a first surface (20) and an opposed outer surface (22) and defines an uncompressed thickness dimension (24) as a longest length of a straight axis (26) extending from the first surface (20) to the outer surface (22) of an uncompressed section (28) of the galvanic pellicle (18). Uncompressed sections (28) of the pellicle are defined between connected areas (30) and continuous connected areas (32) of the pellicle (18). Any point (35) within any uncompressed section (28) is no more distant from one of a nearest connected area (30) and or a nearest segment (34) of a continuous connected area (32) than about ten times the uncompressed thickness dimension (24) of the pellicle (18), thereby achieving significantly reduced contact resistance.
