Description
Technical field:
The present invention relates to a kind of superhigh-capacitance capacitor with composite carbon nanotube and manufacture method thereof, affiliated field is nanometer technology and energy storage field.
Technical background:
Capacitor with super capacity is a kind of novel energy-storing device between storage battery and traditional sucrose capacitor, the traditional sucrose capacitor is to come store charge by polarization of dielectric, comes store charge and capacitor with super capacity is interaction by electrolyte ion and electrode.Compare with the traditional sucrose capacitor, it has very high specific capacitance, and storable energy density is more than 10 times of traditional sucrose capacitor; Compare with storage battery, its power density is high more than 10 times, has that the characteristic of the especially big electric current of abrupt release and charge efficiency are very high, to recycle the life-span long.
Capacitor with super capacity can be used as the power cell of motor vehicle driving power, solve electric motor car developing " bottleneck ", the composite power source motor vehicle that adds capacitor with super capacity with storage battery, storage battery provides required average power under the normal operating condition, and in climbing, start, required accelerating power is provided by the capacitor with super capacity of parallel connection under the on-position, capacitor with super capacity is as " peak power unit ", can alleviate the peak power pressure of storage battery effectively, make the lasting mileage of the each charging of storage battery increase several times, the life-span that recycles of storage battery is prolonged.Capacitor with super capacity also can be applicable to military aspect, and the especially big starting power of MW level is provided as microwave weapon, laser weapon; Also can be used as the stand-by power supply in the electronic equipment, as the uninterruptible power system of television set, Video Camera, PC, mobile phone; The flash of light, the igniter that can be used for industrial equipment are as the initiation power supply of camera, electric welding machine, magnet charger, X-ray machine, fuel cell.
The mode that capacitor with super capacity forms electric capacity has two kinds of electric double layer capacitance and fake capacitances, and electric double layer capacitance is to cause the face-off of electric charge to produce in electrode/electrolyte interface by aligning of electronics and ion.Fake capacitance is that highly reversible redox reaction or adsorption/desorption process take place electroactive material, thereby realize the storage and the release of electric charge and form electric capacity on electrode surface or the body two dimension or accurate two-dimensional space in mutually.The specific capacitance that the fake capacitance mode forms can reach more than 10 times of electric double layer capacitance.The device corresponding with top two kinds of capacitive way is double electric layer capacitor and fake capacitance device.
Usually double electric layer capacitor mainly with active carbon with high specific surface area, activated carbon fiber, carbon aerogels etc. as electrode material, but these material conductivity are relatively poor, capacitor produced equivalent series resistance is big; In addition, it is 2nm or littler micropore that a large amount of apertures are arranged in the active carbon, and electrolyte ion is difficult to enter in these holes, so its specific area utilance is low; And have so-called " dead hole " on the structure, this makes that its frequency response characteristic is poor.In recent years, because the discovery of carbon nano-tube is used carbon nano-tube and caused researcher's attention as the capacitor with super capacity electrode material, carbon nano-tube is the nanoscale tubular material by the curling hollow that forms of single or multiple lift graphite face.Under certain shape and size condition, carbon nano-tube has good electrical conductivity; Carbon nano-tube is interweaved to twine and forms network structure, and mesh size mainly is distributed between the 2-50nm, has huge effective ratio area, is fit to the formation of electric double layer capacitance; Connect mutually between the mesh of carbon nano-tube three-dimensional network, do not have the structural what is called of active carbon " dead hole ".But carbon nano-tube mainly is to form electric double layer capacitance, and specific capacitance is less relatively, is about 100F/g (pressing the single electrode active material calculates).As Ma Renzhi, Wei Bingqing, Xu Cailu, wait on " Chinese science " magazine (E collects, and 2000,30 (2): " based on the ultracapacitor of carbon nano-tube " 112-116) delivered.
And the fake capacitance device is often with metal oxide RuO
2Be electrode material, RuO
2The conductance height, the specific capacitance height of gained capacitor with super capacity, but RuO
2Cost an arm and a leg, seek cheap alternative RuO
2Electrode material cause researcher's interest.As: Wang Xiaofeng etc. " research of nickel oxide ultra-capacitor " that delivers (2001,25 (3)) on " power technology " magazine.Oxide (NiO with nickel
x) be electrode material, but the oxide (NiO of nickel
x) conductivity is relatively poor, the equivalent series resistance of gained capacitor with super capacity is big.In addition, the processability of transition metal oxide is poor.Another kind of fake capacitance device electrode material is a conducting polymer, comprises polyaniline (PAN) and derivative thereof, polythiophene (PTH) and derivative thereof, polypyrrole (PPY) and derivative thereof, poly-to benzene (PPP) and derivative, coalescence benzene (PAS) and derivative thereof; Thereby the capacitor with super capacity based on conducting polymer can form the bigger specific capacitance of fake capacitance acquisition, but the conductivity of conducting polymer is also poor.In addition, the mechanical strength of conducting polymer is low.
The performance of electrode material decision capacitor with super capacity, carbon nano-tube can reach higher conductivity in the electrode material above-mentioned, but it mainly is to form electric double layer capacitance, specific capacitance is less relatively.And transition metal oxide and conducting polymer can form fake capacitance, obtain higher specific capacitance, but conductivity are relatively poor.This means that present capacitor with super capacity electrode material is being difficult to take into account aspect high specific capacitance amount and the high conductivity.In addition, the transition metal oxide processability is poor, and the conducting polymer mechanical strength is low, and this all will influence the performance of capacitor with super capacity.
" carbon-doped nanometer tube capacity with very high capacitance " of people such as Fu Xutao application, number of patent application is: 00136008.6 patent of invention is compound with active carbon (or activated carbon fiber) and carbon nano-tube, as the capacitor with super capacity electrode material, but no transition metal oxide or conducting polymer in this material, be difficult to form fake capacitance, the ratio electric capacity of gained is little." the using the ultracapacitor and the manufacture method of the electrode of new material " of people such as Li Yongxi application, number of patent application is: 01109703.5 patent of invention with carbon nano-tube or nickel-plating carbon nanotube as vast capacity ion-conductance container electrode material, but no transition metal oxide or conducting polymer in this material are difficult to form fake capacitance; In addition, this material cost is too high.And separate sparkling and crystal-clear " electrochemical super-capacitor and the manufacture method " that waits people's application, number of patent application is: 00119499.2 patent of invention is the positive electrode of vast capacity ion-conductance container with the oxide or the hydroxide of nickel, with porous large tracts of land charcoal is negative material, but the oxide of nickel or the poorly conductive of hydroxide, the equivalent series resistance of gained capacitor with super capacity is big.
