Abstract
A sealed capacitor, which may be hermetic, having a generally flat, planar geometry, is described The capacitor includes at least one electrode provided by a metallic substrate having a capacitive material contacted thereto. The coated substrate can provide at least one of the casing side walls itself or, be connected to the side wall. A most preferred form of the capacitor has the conductive substrate provided with the capacitive material formed from an ultrasonically generated aerosol.
Claims33
A capacitor, which comprises:
- a) a casing;
- b) a first electrode comprising a capacitive material as a first electrode active material provided on at least one conductive substrate in electrical contact with a first electrode terminal wherein at least a portion of a side wall of the casing is provided by the at least one conductive substrate or the at least one conductive substrate is in electrical contact with the side wall forming the casing for the capacitor, and wherein the capacitive material is provided as an ultrasonically generated aerosol of the first electrode active material;
- c) a second electrode provided inside the casing and connected to a second electrode terminal;
- d) a separator provided between the first electrode and the second electrode to prevent electrical short circuit contact between the first and second electrodes;
- and
- e) an electrolyte activating and electrically associating the electrodes.
