摘要：
A capacitor having at least two side-by-side anodes with a cathode current collector disposed between the anodes and housed inside a casing is described. Cathode active material is supported on the opposed major faces of the current collector and the current collector/cathode active material subassembly is housed in a first separator envelope. The first separator envelope is positioned between the side-by-side anodes and this electrode assembly is then contained in a second separator envelope. The two anodes can be connected in parallel inside or outside casing, or they can be unconnected to each other. There is also cathode active material supported on inner surfaces of the casing in a face-to-face alignment with an adjacent one of the anodes. That way, the second separator envelope also prevents direct physical contact between the anode pellets and the cathode active material supported on the casing sidewalls.
