An electromechanical battery composed of a parallel plate capacitor having a fixed position plate and a second moveable plate, wherein the moveable plate is constrained by a mechanical spring having a non-linear force-displacement relationship. In another embodiment the spring is replaced by an unrolling/rolling foil plate whose degree of roll is dependent upon the amount of charge held by the capacitor. Furthermore, an electromechanical battery composed of a multi-plate capacitor having a first stack of elastic flexing conducting plates interleaved with a second stack of elastic flexing conducting plates, and a plurality of electrically insulating protrusions disposed between the plates, such that mutual motion as engendered by the application of a voltage between the first and the second electrical connections, is constrained at different positions across the area of the plates by contact with at least some of the protrusions. Each of these arrangements result in a battery which provides and maintains a constant voltage as current is drawn from it during discharge. |
