Extended life capacitor and method
An extended life capacitor is described comprising, in combination: an enclosing body having an interior surface formed from a material highly resistance to corrosion by the electrolyte of the capacitor; double layer capacitor cells inside the enclosing body and having first and second electron-conducting end members; the capacitor cells including a high surface area carbon material impregnated with an electrolyte; means providing electrical connection external to the body, mutually insulated, to the first and second end members of the plurality of capacitor cells as anode and cathode; means to inhibit the loss of electrolyte from the interior to the exterior of the capacitor body; and the inhibiting means including an hermetically sealed body and high purity components.
