Abstract
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.
