Definitions
- the invention relates to the creation of energy-accumulating electric capacitors, the charge of which accumulates at the interface between two media - an electrode and an electrolyte, therefore called “capacitors with a double electric layer”, as well as “supercapacitors”, “hybrid capacitors”, “hypercapacitors” (Japan) , “Ultracapacitors” (Germany, USA), “electrochemical capacitors” (France, Canada), “ionistors” (Russia and other CIS countries).
- capacitors with a double electric layer largely determines the possibility and expediency of their use primarily in transport electric and hybrid vehicles.
- Another promising area is the use as “compensators” in power plants with unstable characteristics, such as wind-power generating plants, power plants with solar batteries, tidal power plants.
- Double electric layer capacitors differ in the type of electrode materials used in them, as well as the electrolytes used.
- the first materials used are one of three types: materials based on activated carbon, metal oxides and conductive polymers.
- the electrolyte may be aqueous or organic.
- the most common type of double-layer capacitors are capacitors with activated carbon electrodes.
- activated (highly porous) carbon materials can achieve a tank density of the order of 10 f / cm 3 or more. (http://www.electrosad.ru/Electronics/SuperCon.htm)
- a known electric capacitor electrode with a double electric layer made of a mixture of particles of activated carbon, dispersed carbon (graphite or soot), a porous elastic dielectric and a polymer binder (WO 94/01879).
- Activated carbon consists of a mixture of large particles (1-100 microns) and small particles (0.05-1 microns).
- Porous plastic particles of 1-50 microns in size or fibers of porous dielectric materials with a diameter of 0.3-50 microns and a length of 0.1-5 mm were used as porous elastic dielectric.
- polyvinyl alcohol, polysaccharides, rubber, fluoroplastics are mainly used as a polymeric binder.
- the capacitor assembled from these electrodes has a low capacitance, a sufficiently large resistance due to the use of a porous elastic dielectric, and relatively low mechanical strength.
- These disadvantages are to some extent eliminated in the electrode according to RF patent No. 2172037 made of a sorbent, for example, activated carbon bonded by thermoplastic polymer particles uniformly distributed between activated carbon particles and having an average particle size of 0.08-0.9 of the average particle size of activated carbon .
- the electrode according to the said patent can also be made of activated carbon and graphite or soot powder, bonded together by polymer particles, while for the most uniform distribution over the entire volume of the electrode, the average particle size of graphite or soot should be 0.02-1.4 of the average particle size of activated carbon.
- the electrodes may further comprise activated carbon tissue bonded to their surface with one or both sides of the polymer particles, while the average size of the fabric thread is 0.2-0.5 of the average particle diameter of the sorbent.
- this electrode has insufficient strength and, in addition, its manufacturing technology is complex. Activated carbon fabric is laid in a mold, then a homogeneous mixture of granular sorbent and polymer is loaded there, while manufacturing a bipolar electrode, carbon fabric is also laid on top, pressed, followed by heat treatment. Then the mold is cooled and the finished electrode is removed.
- the objective of the present invention is to provide a capacitor electrode with a double electric layer, which, with good electrical resistance and capacitance, would have increased mechanical strength.
- Another objective of the present invention is to provide an electrode with a simple manufacturing technology.
- the substrate is made of thermally expanded graphite. (TWG) impregnated with a high polymer hydrocarbon, in particular ceresin.
- TWG thermally expanded graphite
- the specified fabric was fixed on a substrate using an adhesive resistant to electrolyte used in a capacitor.
- the carbon-activated fabric can be attached to the substrate from two sides or from one side.
- the electrode In the first case, the electrode will be bipolar and, when assembling the capacitor, it will occupy an intermediate position (among the electrodes), in the second case, the electrode will be unipolar and, accordingly, end in the electrode assembly.
- thermally expanded graphite substrates also called “flexible graphite” or TEG
- Thermally expanded graphite of various brands can be used in the invention: Grafoil®, owned by UCAR Carbon Co. Inc; GRAPH-LOCK® owned by Garlock; Graflex, owned by the Russian company Unihimtek.
- Thermally expanded graphite an elastic, compressible, resilient, chemically inert material, fireproof, and heat-resistant.
- a very valuable quality of thermally expanded graphite is that its properties are practically independent of temperature.
- Thermally expanded graphite has anisotropic electrical and thermal conductivity. It has found wide application in the chemical, petrochemical, oil refining industries, in the automotive industry, and also as a heat and noise insulation material. The TWG also found application in electronics as a shielding material and for heat removal.
- thermally expanded graphite as elasticity and compressibility make it possible to produce it in the form of sheets and use it as a structural material, which is the case in this invention, where it is used as an electrode substrate.
- Example 1 The manufacture of a unipolar (end) electrode.
- the substrate of thermally expanded graphite of Graphlex is impregnated in ceresin at a temperature of PO-140 ° C in a vacuum oven.
- the depth of the vacuum is 0.5-Yu, 8 K 7 CM 2 .
- the activated carbon fabric (AUT) UVIS-AK-T-040 (TU 1916-002-18070047-2007) is treated along the contour with an aqueous emulsion of latex grade BNK-302 (TU 38.103602-86) to a width of 2 - ⁇ - 5 mm for bonding fibers tissue and impregnated in an electrolyte with a density of 1, 25-I, 28 7 CM 2 .
- the fabric is squeezed between plates with a specific pressure of 7- ⁇ 8 "" Weem 2 .
- the manufacturing technology is the same as in example 1 with the difference that the fabric of activated carbon fabric is glued to the substrate on both sides of it.
