Description
Technical field
The invention belongs to the electric conducting material technical field, particularly a kind of carbon nano-electrode material that is used for ultracapacitor and preparation method thereof.
Background technology
Ultracapacitor is a kind of equipment that utilizes electrochemical capacitance principle to come store electrical energy; Has the power density height; Advantages such as long service life can be used as the storage (like wind energy and tidal energy) of erratic current, and the standby lighting power supply of the large-scale vehicles (like steamer or aircraft) etc.But compare with lithium ion battery, the energy density of ultracapacitor is lower, and its application at aspects such as the vehicles and mobile electronic devices receives certain limitation.
Present business-like electrode material mainly is an activated carbon, but active carbon can only be used for the capacitor of operating voltage less than 3 V.And the Graphene of SWCN, double-walled carbon nano-tube and 1 layer ~ 3 layers has steady chemical structure, and specific area is big, and the characteristics that conductivity is good are regarded as the ideal electrode material of the capacitor of making high-energy-density of future generation.But the diameter of SWCN or double-walled carbon nano-tube is little, and the Van der Waals force between the tube and tube is strong, is prone to bunchy and difficult the dispersion; And 1 layer ~ 3 layers Graphene just becomes multi-layer graphene after mutually superimposed; Both of these case all causes specific area to reduce, and capacitive property descends.The hybrid of one or more that present up-to-date research thinking is preparation SWCN or double-walled carbon nano-tube and Graphene; Utilize the two various structure characteristic; After having formed the alternate structure of a layer graphene and one deck SWCN or double-walled carbon nano-tube, just can overcome the two shortcoming separately.But directly prepare the method for this hybrid at present, productive rate is low, and purity is low, and the number of plies of the wall number of CNT and Graphene is wayward.Utilize SWCN or double-walled carbon nano-tube behind graphene oxide and the functionalization to carry out self assembly, can form similar structure, but when under high voltage, using, need in hot environment, further remove various functional groups.And high temperature action causes the structure of gained to be reunited, and the dispersion effect in ion liquid type electrolyte is not good, and this method treatment step is long simultaneously, and yield is low, and is with high costs.
Summary of the invention
The shortcoming that the present invention is directed to above-mentioned electrode material and preparation method thereof has been carried out the improvement of novelty, has proposed a kind of carbon nano-electrode material that is used for ultracapacitor and preparation method thereof.
The invention provides a kind of carbon nano-electrode material that is used for ultracapacitor; It is characterized in that: said carbon nano-electrode material is formed by SWCN or double-walled carbon nano-tube and Graphene hydridization; Wherein the content of SWCN is 0 wt% ~ 99 wt%; The content of double-walled carbon nano-tube is 0 wt% ~ 99 wt%, and the content of Graphene is 1 wt% ~ 99 wt%.
The invention still further relates to the above-mentioned preparation method who is used for the carbon nano-electrode material of ultracapacitor, it is characterized in that: these method concrete steps are following:
With CNT and Graphene in oxygen content less than 0.5 ppm; In the environment of water content less than 1 ppm; Be scattered in 20 ℃ ~ 80 ℃ ionic liquid (the two fluoroform sulfimide salt of N-methyl butyl pyrrolidines, the two fluoroform sulfimide salt of N-methyl butyl piperidines; In the two fluoroform sulfimide salt of 1-ethyl-3-methylimidazole, 1-ethyl-3-methyl imidazolium tetrafluoroborate, the two fluoroform sulfimide salt of trimethyl third ammonium, the two fluoroform sulfimide salt of diethyl first QAE quaternary aminoethyl methyl ether and the two fluoroform sulfimide salt plasma liquid of 1-hexyl-3-methylimidazole one or more) in, the total weight of controlling all carbon nano-electrode materials is ion liquid 1% ~ 20%.About 1 h ~ of mechanical agitation is 20 hours under the speed of 100 rpm ~ 4000 rpm; Or the carbon nano-electrode material mixed back sonic oscillation 1 h ~ 24 hours with ionic liquid; Or, extrude with screw extruder with after carbon nano-electrode material and the grinding of ion liquid mixture process; Or the combination of above-mentioned two or three method, thereby prepare a kind of carbon nano-electrode material that is used for ultracapacitor.
The present invention compared with prior art has following beneficial effect:
1, ion liquid dielectric property is strong, can overcome the Van der Waals force of list/double-walled carbon nano-tube interfascicular, and the electrostatic force between 1 layer ~ 3 layer graphenes, thereby effectively obtains the two alternate hybrid structure.Because the ionic liquid body is exactly the desirable electrolyte of high voltage ultracapacitor; So the mixture of itself and carbon nano-electrode material just can directly be used to construct capacitor; So not only make the preparation process of hybrid simplify; Also make the ultracapacitor preparation process shorten, its cost is than the cost low 60% ~ 90% with prepared this type hybrid of traditional graphene oxide method.
2, disperse to obtain the hybrid of carbon nano-electrode material through ionic liquid after, just can directly use, all processes do not need at high temperature to operate, therefore the easy maintenance of structure of resulting list/double-walled carbon nano-tube and Graphene hybrid.Therefore, with the hybrid of this method preparation this type hybrid, when being used for ultracapacitor, can improve 0.5 times ~ 1.5 times based on the energy density of carbon nano-electrode material than traditional graphene oxide method preparation.
3, disperse to prepare the method for carbon nano-electrode material through ionic liquid, than the method through this type of catalyst method in-situ preparing material, preparation temperature is low, and product purity is high.Therefore prepare the carbon nano-electrode material with this method and will descend 4 times ~ 10 times than cost through this type of catalyst method in-situ preparing material.
4, disperse to prepare the method for carbon nano-electrode material through ionic liquid; Highly purified list/the double-walled carbon nano-tube that can use any preparation method to obtain; And highly purified 1 layer ~ 3 layers Graphene for preparing of any method; Therefore do not receive the restriction of process of the method (like graphite arc method or chemical vapour deposition technique) of any direct this class formation of preparation, have scalable characteristic.
