The ubiquitous capacitor is a key energy storage element in electronic systems but it turns out that there are many subtleties associated with capacitor design and operation. As an energy storage element, it is important that the capacitor retain most of the stored energy for a specified period of time. Electron tunneling can limit storage time and it is argued that capacitor architecture is not a major factor in determining the peak energy retention as a function of dielectric constant. Surprisingly, for a given leakage period and level of energy preservation, the maximum energy stored per unit volume does not strongly depend on the capacitor configuration. The double-layer ...
