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 sealed capacitor, which may be hermetic, having a generally flat, planar geometry, is described. The capacitor includes at least one electrode provided by a metallic substrate having a capacitive material contacted thereto. The coated substrate can provide at least one of the casing side walls itself or, be connected to the side wall. A most preferred form of the capacitor has the conductive substrate provided with the capacitive material formed from an ultrasonically generated aerosol.

Abstract: An electrochemical cell including an alkali metal anode and a cathode, one of the anode or cathode being connected to a structure for making electrical connection from a load to the cell, the other of the anode or cathode having main and alternate portions, a main terminal connected to the main anode or cathode portion for making electrical connection between a load and the cell, and an alternate terminal connected to the alternate anode or cathode portion for making electrical connection between a load and the cell, so that the main anode or cathode portion first is discharged with the alternate portion held in reserve, whereupon when the main portion reaches end of life the alternate anode or cathode portion is discharged. The main and alternate anode or cathode portions are insulated from each other, and the anode preferably is of lithium.
