Claim:
A wet electrolytic capacitor comprising: a casing that defines an opening and a sidewall surrounding an interior, wherein an electrochemically active cathode material is located on at least a portion of the sidewall; an anode positioned within the interior of the casing, wherein the anode is formed from a porous anode body that contains a dielectric layer, the anode comprising an anode lead extending therefrom; an electrolyte that is in electrical contact with the anode and the electrochemically active material; a lid sealed to the casing opening that has an upper surface and lower surface, wherein the lower surface faces toward the interior of the casing, wherein the lid further defines an internal orifice; a hermetic seal positioned within the orifice of the lid, the hermetic seal having a lower surface that faces toward the interior of the casing; and a liquid seal that coats a substantial portion of the inner surface of the lid and the hermetic seal, wherein the liquid seal contains an insulative sealant material.
