Abstract
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.
