A capacitor is described. the capacitor includes a casing; a cathode of an active material of at least an oxide of a first metal provided on a substrate, wherein the active material is characterized as being of a substantially homogeneous coating formed by sputtering a target of the first metal in a vacuum chamber; an anode spaced from the cathode coating; and an electrolyte in contact with the cathode coating and the anode. The casing contains the anode, the cathode and the electrolyte. A method and apparatus for providing the sputtered coating is also disclosed.

Sputtered ruthenium oxide coatings in electrolytic capacitor

Deposition of a metal-containing reagent solution or suspension onto a conductive substrate by various pad-printing techniques is described. The result in a pseudocapacitive oxide coating, nitride coating, carbon nitride coating, or carbide coating having an acceptable surface area for incorporation into an electrolytic capacitor, such as one have a tantalum anode.
