Abstract: A capacitor assembly comprising a casing, an anode pack housed within the casing and comprising two or more anode pellets of anode active material electrically connected to each other by a bridge, and a cathode comprised of cathode current collectors including major faces with cathode active material provided thereupon is described. The bridge, which spans between sidewalls of the anode pellets, helps maintain them in a parallel alignment. The bridge is also a convenient location to connect the feedthrough wire that exits the casing through a glass-to-metal seal. The cathode current collectors are disposed between adjacent anode pellets and are electrically connected to each other and to the casing. A feedthrough wire electrically connected to the anode pack extends outside the casing in electrical isolation there from. An electrolyte is provided to activate the anode and the cathode.

Abstract: A capacitor a casing of first and second casing members, a feedthrough electrically insulated from the casing and extending there from, first and second anodes electrically connected to each other within the casing, a cathode, and an electrolyte is described. The first anode is electrically connected in parallel to the second anode by a first anode wire having opposite ends contacting the respective first and second anodes. A feedthrough wire extending outside the casing and electrically isolated there from is electrically connected to the first anode wire intermediate the first and second anodes. The cathode is disposed between the first and second anodes.

Abstract: A capacitor comprising a casing of first and second casing members, a feedthrough electrically insulated from the casing and extending there from, first and second anodes electrically connected to each other within the casing, a cathode, and an electrolyte. The casing comprises first and second casing members, the first casing member having a first face wall joined to a surrounding side wall, and the second member having a second face wall, wherein the first and second casing members are secured together.

Abstract: An enclosure for an electrical energy storage device such as a wet tantalum electrolytic capacitor or an electrochemical cell such as a lithium/silver vanadium oxide cell is described. The enclosure comprises two metallic casing components or portions. The first is a drawn member having a planar face wall supporting a surrounding sidewall and is shaped to nest the anode, cathode and intermediate separator components. The surrounding sidewall has an annular flange at its outer periphery. A mating cover is a stamped planar piece of similar material whose periphery fits inside the annular flange or rim as a complementary piece.
