These directional definitions are merely intended to assist in describing and claiming the invention and are not intended to limit the invention in any way. In addition, reference numerals that are introduced in the specification in association with a drawing figure may be repeated in one or more subsequent figures without additional description in the specification in order to provide context for other features. Generally, the following disclosure refers to electrodes for ultracapacitors using water soluble binders and a method of manufacturing large size ultracapacitors using the above electrodes.
[0017] Referring to FIG. 1 , an ultracapacitor 100 according to an exemplary embodiment of the present invention is shown. Ultracapacitor 100 includes a plurality of metallic electrode substrates 102. Each of the plurality of electrode substrates 102 has a coated portion 102a and an uncoated portion 102b. Substrate 102 is coated with a coating material 104, forming coated portion 102a. Substrate 102 may be aluminum, carbon coated aluminum foil, and any polymer primed aluminum foil (with or without carbon) or any other suitable material.
[0018] Coating 104 includes an activated carbon material with high surface area 106 mixed with a water soluble binder 108 and water to form a slurry. A water soluble thickener 110 may be added to the slurry to thicken the slurry for application onto electrode substrates 102. Additionally, a conductive additive or additives selected from the group consisting of carbon black, acetylene black, carbon fibers, coke, high surface area carbon and graphite may optionally be added to the slurry.
[0019] Exemplary high surface area activated carbon material 106 may be activated carbon, activated carbon nano foam, or other suitable carbon-based material. The amount of carbon in the slurry ranges between about 60 and about 95 weight percent. An exemplary surface area of activated carbon material 106 may be between about 100 to be about 2500 square meters per gram (m2/g).
[0020] Exemplary water soluble binder 108 may be selected from the group consisting of: poly vinyl alcohol, poly acrylic acid, polymethacrylic acid, polyethylene oxide, polyacrylamide, poly-N-isopropylacrylamide, poly-N,N-dimethylacrylamide, polyethyleneimine, polyoxyethylene, polyvinylsulfonic acid, poly (2- methoxyethoxyethoxyethylene), butadiene-acrylonitrile, carboxymethylcellulose, (CMC), polyvinylpyrrolidone, poly(allylamine), xanthan gum, guar gum, chitosan, polyvinyl acetate, gelatin, casein, styrene butadiene rubber (SBR), butadiene-acrylonitrile, rubber (NBR) hydrogenated NBR (HNBR), epichlorhydrin rubber (CHR), acrylate rubber (ACM), a cellulose from the group consisting of natural cellulose, physically and /or chemically modified cellulose, natural polysaccharides, chemically and /or physically modified polysaccharides, hydroxy methyl cellulose and methyl ethyl hydroxy cellulose, poly(carboxylic acid) and combinations and/or copolymers thereof.
[0021] Exemplary poly(carboxylic acids) are: polylactic acid (PLA), polyacrylic acid, polysuccinic acid, poly maleic acid and anhydride, poly furoic (pyromucic acid), poly fumaric acid, poly sorbic acid, poly linoleic acid, poly linolenic acid, poly glutamic acid, poly methacrylic acid, poly licanic acid, poly glycolic acid, poly aspartic acid, poly amic acid, poly formic acid, poly acetic acid, poly propoionic acid, poly butyric acid, poly sebacic acid, and copolymers thereof. When using poly(carboxylic acids), the pH of binder 108 can be neutralized by adding LiOH or other suitable material. The weight percent of binder in the slurry ranges between about 1 and about 20 percent.
[0022] Exemplary water soluble thickener 110 may be selected from the group consisting of natural cellulose, physically and/or chemically modified cellulose, natural polysaccharides, chemically and/or physically modified polysaccharides, carboxymethyl cellulose, hydroxy methyl cellulose and methyl ethyl hydroxy cellulose. The total solid weight percent of the thickener in the slurry ranges between about 1 and about 5 weight percent such that the weight percentage of the carbon, the binder, the thickener, and the conductive additive equals 100 percent. Water is added to the solid components to form the slurry such that the weight percent of the water in the slurry ranges between about 20 and about 70 percent.
[0023] The slurry is coated onto coated portion 102a of electrode substrates 102 and dried until the moisture level is less than 1000 parts per million (ppm) or more preferably less than 200 ppm in the electrode 102a. After drying, electrode substrates 102 are cut into desired size and shaped electrodes 112, with uncoated portion 102b formed into terminal tabs 114. Electrodes 112 are stacked on top of each other, with a separator 120 inserted between adjacent electrodes 1 12, forming an electrode stack 116. Separator 120 may be a micro porous material such as, for example polyethylene or polypropylene-type separator or plasticized polymer type separators which are bonded to the electrodes. Separator 120 extends beyond coating 102a as shown in FIG. 1 to prevent direct contact between adjacent electrodes 102.
[0024] Terminal tabs 114 are alternated on different sides of adjacent electrodes 112, with terminal tabs 114a on one side of ultracapacitor 100 being "positive" terminal tabs 114a and terminal tabs 114b on the other side of ultracapacitor 100 being "negative" terminal tabs 114b. Terminal tabs 114a and 114b both extend from the same side (i.e., top) of ultracapacitor 100, resulting in less complexity in connecting terminal tabs 114 to an electrical circuit than having one set of terminal tabs extending from the top of ultracapacitor 100 and the other terminal tabs extending from the bottom of ultracapacitor 100.
[0025] An equal number of positive terminal tabs 114a as negative terminal tabs 114b are provided, with positive terminal tabs 114a coupled to each other in parallel and negative terminal tabs 114b coupled to each other in parallel as well to form a capacitive circuit, or bundle. Ultracapacitor 100 may include multiple bundles, with the multiple bundles coupled together in series to achieve a desired capacitor voltage.
[0026] Referring to FIG. 2, the bundles are enclosed in packaging that includes a pressure regulated large format cell pouch 130. Cell pouch 130 includes a metallic lamination, with the inside of pouch 130 being formed from a heat sealable material, such as, for example, an aluminum pouch bag material supplied by Showa Denko, Japan.
[0027] Positive terminal tabs 114a are coupled to a positive terminal 132 inside cell pouch 130 and negative terminal tabs 114b are coupled to a negative terminal 134, also inside cell pouch 130. The feature of providing these couplings inside cell pouch 130 provides improved safety and eliminates hazards during handling of ultracapacitor 100.
[0028] An insulator block 140 provides structure and a pass-through for terminals 132, 134 in a hermetic fashion. Insulator block 140 provides for sealing of cell pouch 130 to seal around the pass-throughs for terminals 132, 134. An exemplary packaging is disclosed in U.S. Patent Application Serial No. 12/729,790, filed March 23, 2010, which is owned by the assignee of the present invention and is incorporated herein by reference in its entirety as though fully set forth.
[0029] Referring back to FIG. 1 , ultracapacitor 100 further includes an electrolyte 142 that is inserted into cell pouch 130. The electrolyte 142 may be an aqueous or a non-aqueous medium with an appropriate salt. An exemplary organic electrolyte may be tetraethylammoniumtetrafluoroborate (TEABF4) in acetonitrile (ACN) or propylene carbonate (PC).
[0030] Cell pouch 130 may be stored in a housing assembly 146. An exemplary housing assembly 146 is a nested heatsink housing assembly disclosed in U.S. Patent Application Serial No. 12/730,642, filed March 24, 2010, which is owned by the assignee of the present invention and is incorporated herein by reference in its entirety as though fully set forth. The ultracapacitor 100 according to the present invention has a capacity of between about 30 and about 40 Farads.
[0031] Referring to the flowchart 500 of FIG. 3, an exemplary method of manufacturing ultracapacitor 100 is provided. In step 502, a slurry is formed comprised of high surface area activated carbon material 106, water soluble binder 108, water soluble thickener 1 10, and water. In step 504, substrate 1 14 is coated with the slurry and in step 506, the coating is dried onto the substrate 114.
[0032] In step 508, a plurality of the substrates 114 are stacked on top of each other, while separating adjacent substrates from each other with micro porous separator material 120, forming a stack. In step 510, the stack is inserted into cell pouch 130 and in step 512, electrolyte 142 is added to the stack in cell pouch 130.
[0033] While the principles of the invention have been described above in connection with preferred embodiments, it is to be clearly understood that this description is made only by way of example and not as a limitation of the scope of the invention.
