Abstract
Fabricating a capacitor includes obtaining a sheet of material having a first phase of an anode metal oxide on an anode metal. The anode metal oxide is an oxide of the anode metal. A portion of the first phase of the anode metal oxide is converted to a second phase of the anode metal oxide. At least a portion of the second phase of the anode metal oxide is removed from the sheet of material. In some instances, the first phase of the anode metal is converted to the second phase of the anode metal oxide as a result of the process used to extract a capacitor anode from the sheet of material.
