Abstract:
A hybrid capacitor includes an electrically non-conductive rigid or semi-rigid porous honeycomb structure having cells extending along a common direction, the cells having a plurality of cross-sectional shapes. The honeycomb structure is desirably formed of a material that is stable at temperatures of 300 or more, such that high temperature processing can be used to help ensure high purity of the final product. The material of the structure may desirably be an oxide or non-oxide ceramic, such as cordierite, silicon nitride, alumina, aluminum titanate, zircon, glass, or glass-ceramic. The plurality of shapes of the cells includes larger shapes in which cells are disposed non-galvanic electrodes, with galvanic electrodes disposed in cells of other shapes.
