ABSTRACT:
A porous aluminum anode is used in a capacitor. The porous anode is constructed by a solid freeform fabrication (SFF) process and has a plurality of pores. Each of the plurality of pores has a pore size. An electrolyte is infiltrated in the plurality of pores. An oxide layer is formed on the aluminum surface to provide a dielectric for the capacitor.
