Method of pad printing in the manufacture of capacitors

摘要

Deposition of a metal-containing reagent solution or suspension or a carbon nanotube-containing suspension onto a conductive substrate by various pad-printing techniques is described. In the case of a metal-containing solution or suspension, a pseudocapacitive oxide coating, nitride coating, carbon nitride coating, carbide coating, or carbon nanotube coating results. In any event, the active coating has acceptable surface area for incorporation into an electrical energy storage device, e.g. an electrolytic capacitor, such as one having a tantalum anode.
