摘要:
Composite carbon electrodes for use in, for example, Capacitive Deionization (CDI) of a fluid stream or, for example, an electric double layer capacitor (EDLC) are described. Methods of making the composite carbon electrodes are also described. The composite carbon electrode comprises an electrically conductive porous matrix comprising carbon; and an electric double layer capacitor, comprising an activated carbonized material, dispersed throughout the pore volume of the electrically conductive porous matrix.

A method of assembling optoelectronic and/or photonic components, said method comprising: (i) providing at least two optoelectronic and/or photonic components; (ii) aligning and situating these components relative to one another and in close proximity with one another so as to: (a) provide optical coupling between these components; and (b) maintain the distance d between the adjacent parts of these components, where d is 0 to 100 µm; (iii) adhering these components to one another with while maintaining optical coupling therebetween; and (iv) laser welding these components together while maintaining optical coupling therebetween.

An ultracapacitor or hybrid capacitor includes an electrically non-conductive rigid or semi-rigid porous honeycomb separator structure having cells extending along a common direction and supporting current collector structure(s) thereon. The current collector structure may be porous and extend continuously on all inner surfaces of a cell of the honeycomb structure, or may extend along the common direction on separate portions of the inner surfaces of a cell. The material may desirably be an oxide or non-oxide ceramic, such as cordierite, silicon nitride, aluminum titanate, alumina, zircon, glass, or glass-ceramic.

摘要:
Capacitive devices are described having electrical interconnects (12) of electrodes (10) which possess efficient electrical contact between current collectors, electrical isolation (18) of electrodes, and/or electrochemical stability, while minimizing the mechanical stress and strain applied to the electrodes. The capacitive devices are adaptable to a wide range of electrode dimensions and electrode stack heights. This stack of planar electrodes could be used in double layer capacitor or in capacitive device for charge seperation of ions in solution.

An 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.
