Abstract
A capacitor is described. The capacitor includes a casing of first and second casing members secured to each other to provide an enclosure, a feedthrough electrically insulated from the casing and extending there from through a glass-to-metal seal, first and second anodes electrically connected to each other within the casing, a cathode, and an electrolyte. The cathode is of a cathode active material deposited on planar faces of the first and second casing members. There is also a cathode current collector disposed intermediate the first and second anodes. The cathode current collector supports cathode active material on both of its major faces and includes a tab that is directly electrically connected to a ferrule of the glass-to-metal seal. That way, the casing is the negative terminal for the cathode and a feedthrough pin extending through the glass-to-metal seal is the positive terminal for the anode of the capacitor.
