A capacitor anode formed from ceramic particles (eg, Nb 2 O 5 , Ta 2 O 5 ) that can be chemically reduced to form a conductive composition (eg, NbO, Ta). For example, a slip composition comprising ceramic particles is first formed and deposited in the form of a thin layer on a carrier substrate. If desired, multiple layers can be formed to achieve the target thickness of the anode. Once formed, one or more layers are heat treated to reduce the ceramic particles to form a conductive anode. Unlike ordinary press-formed anodes, the slip-formed anode of the present invention is thin, has a high aspect ratio, and is uniform in density, which improves volumetric efficiency and equivalent series resistance (ESR).
