A capacitor comprising a cylindrical casing sidewall extending to closed first and second end walls and an anode assembly housed therein including a first, second and third anodes is described. Each anode comprises an anode sidewall extending to first and second anode end walls and a conductive lead extending therefrom. The anodes are in a side-by-side relationship within the casing with their respective sidewalls parallel to each other. The cathode of the capacitor may include a first conductive substrate supporting a cathode active material. The conductive substrate is wrapped around the anodes, and the cathode active material is disposed on the substrate at locations such that the respective sidewalls of the anodes are opposed by cathode active material. A separator is positioned between the side-by-side anodes and the cathode. The open volume within the casing is filled with an electrolyte, and the casing is hermetically sealed.
