A capacitor structure comprises a shallow drawn case having a first major
side and a peripheral wall extending therefrom, the first major side
having a first interior surface and the wall having a peripheral interior
surface. A lid is sealingly coupled to the case along adjacent edges of
the lid and the wall, the lid and said case forming an encasement of the
capacitor structure, the lid comprising a second interior surface. A
cathode material is disposed proximate the first and second interior
surfaces, and an anode is positioned intermediate the cathode material and
has a peripheral portion positioned proximate the adjacent edges. A
protective layer on the peripheral portion protects the anode during the
sealing process. A first insulative separator is positioned between the
anode and the cathode material.
