摘要:
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.
摘要:
An energy storage device in the form of a cylindrical double layer capacitor (1) includes a plurality of integrally formed first electrode members (2) which each extend between a first end (3) and a second end (4). A plurality of integrally formed second electrode members (5) each extend between a third end (6) and a fourth end (7). As shown, members (5) are interleaved with members (2) such that ends (7) are located intermediate ends (3, 4) of the adjacent members (2). An insulator in the form of carbon layers (8) are disposed between adjacent members (2, 5) to prevent electrical contact therebetween. First contact means in the form of flanges (11) extend from respective ends (3) of each member (2) and electrically connect all the first members. Flanges (11) provide a site for the metallisation of particles thereupon. Those particles form a porous connection layer (12) for an electrical terminal (13) for members (2). Flanges (11) also form a barrier against the ingress of the particles beyond ends (3).
摘要:
A single cell, multi-electrode high performance double layer capacitor includes first (Stack A) and second (Stack B) flat stacks of interleaved electrodes (141) adapted to be housed in a closeable two-part capacitor case (Fig. 12) which includes only a single electrolyte seal (154, 156, 158). Each electrode stack has a plurality of electrodes connected in parallel, with the electrodes of one stack being interleaved with the electrodes of the other stack to form an interleaved stack (141), and with the electrodes of each stack being electrically connected to respective capacitor terminals. A porous separator sleeve (140) is inserted over the electrodes of one stack (Stack B) before interleaving to prevent electrical shorts between the electrodes. The electrodes are made by folding a compressible, low resistance, aluminum-impregnated carbon cloth (136), made from activated carbon fibers, around a current collector foil (132), with a tab (133) of the foils of each electrode of each stack being connected in parallel. The parallel-connected tabs (135, 142) are then connected to the respective capacitor terminals. The height of the interleaved stack is somewhat greater than the inside height of the closed capacitor case, thereby requiring compression of the interleaved electrode stack when placed inside of the case, and thereby maintaining the interleaved electrode stack under modest constant pressure. The closed capacitor case is filled with an electrolytic solution and sealed. A preferred electrolytic solution is made by dissolving an appropriate salt into acetonitrile (CH3CN). In one embodiment, the two parts of the capacitor case (150, 152) are conductive and function as the capacitor terminals.
