- the 500mL/min of body flow 100.
In step 2, the power of plasma cleaner is 1-1000 W.
In step 3, the stamping pressure of tablet press machine is 1- 40MPa.
A kind of array carbon nano tube foam metal composite base plate, is prepared by above-mentioned preparation method.
In the application in energy device field, the energy device includes above-mentioned array carbon nano tube foam metal composite base plate
Ultracapacitor, lithium ion battery, the electrode base board of nickel-based battery and fuel cell.
Present invention firstly provides with the compound concept of the mechanics of array carbon nano tube and foam metal, it is intended to compound to prepare
Destruction of the step such as scattered to array form is avoided in journey;And it is support frame to utilize foam metal, suppresses array carbon nano tube
Because the characteristic of itself high-specific surface area and caused by the structure collapse in electrolyte solution the problems such as, as far as possible keep array carbon receive
The structural intergrity of mitron;Meanwhile array carbon nano tube preparation proposed by the present invention has high precision controllable, with foam metal
The technical characteristic that thickness matches, array structure extending transversely through on foam metal support can be obtained(Fig. 1), farthest
Play the electronics conductive advantages of array carbon nano tube;It is and by the adhesion of array carbon nano tube that active material is further solid
It is fixed, it is added significantly to the cyclical stability of device.In addition, the present invention also demonstrates array carbon nano tube and device is provided with bendable
The performances such as folding, shock resistance.Every advantage as described above is that previously disclosed any structure and preparation method are unable to reach
's(Fig. 2).
The present invention compared with prior art, has the advantages that:
First, inventive process avoids customary preparation methods(Such as scattered, liquid deposition)To array carbon nanotube structural damage, not
In the case of changing carbon pipe microscopic characteristics, the array structure of CNT is maintained;In addition in array carbon nano tube preparation
It is precisely controlled, obtains array structure and be continuous through in foam metal transverse direction, plays the excellent of its electronics conduction to greatest extent
Gesture, be advantageous to the further release of electrode performance, it is specific as follows:
Array carbon nano tube can carry out vertical orderly electric transmission, and vertical orderly electric transmission is more efficient certainly
, and unordered CNT can only carry out unordered electric transmission, inventor did the experiment similar to unordered CNT, performance
It is more far short of what is expected than array carbon nano tube;
Electrode performance refers to that Conventional electrochemical is tested, and needs quick electronics to shift in test process, to conduction needs very
Height, therefore array carbon nano tube electric conductivity vertical direction order transfer, it is more advantageous.
2nd, the present invention is removed array carbon nano tube surface wrap thing, obtained by the surface treatment to array carbon nano tube
Acicular texture;The pattern for being formed as its bottom grown of array carbon nano tube surface wrap thing, in early growth period catalyst
The difference of activationary time, lead to not produce orientation;The process is usually 0.5 ~ 1 minute, and twister is highly 10 μm or so;
In mechanics recombination process, twister can block foam metal hole, hinder the complete insertion of array carbon nano tube, while also can shadow
Ring effective transmission of electronics vertical direction in duct.And the situation that plasma etching is not destroyed in guarantee array body
Under, surface wrap thing is removed, is advantageous to obtain vertical direction biography that is uniform compound with foam metal, while being advantageous to electronics
It is defeated.
3rd, array carbon nano tube foam metal composite base plate of the invention, using array carbon nano tube in pipe range advantage, shape
Into perforation effect, the space for substantially increasing foam metal utilizes, and with reference to the specific surface area advantage of carbon pipe in itself, makes electrode body
System has more preferable effect of impregnation.It is specific as follows:
The infiltration of electrolyte would generally influence the utilization to electrode base board effective volume;And electrolyte needs and electrode material contacts
Competence exertion effectiveness.For energy storage device, too low surface density can cause the infiltration for having an impact electrolyte of capillary force,
It is unfavorable for the performance of battery performance;The infiltration of material is relevant with the hydrophily of material.The hydrophily of foam metal is not so good as array carbon
Nanotube, therefore, the introducing of array carbon nano tube can regulate and control the hydrophily of array carbon nano tube foam metal composite base plate, enter
And regulate and control the infiltration of electrolyte, utilized so as to improve the volume of foam metal.
The loading of active material depends on the specific surface area of electrode material.Specific surface area of carbon nanotube is foam metal
10 ~ 50 times, equivalent to the specific surface area for greatly improving electrode system in the carbon nano-tube filled loose structure to foam metal;
The filling of active material can utilize foam metal and array carbon nano tube both sides specific surface area, larger make use of foam
The effective volume of metal;By conventional plating means, in the surface electrode active material of electrode base board, this part is attached to bubble
The structured surface of foam metal and array carbon nano tube institute, takes full advantage of the high-specific surface area of array carbon nano tube, therefore carry
The volume of high foam metal utilizes.
4th, array carbon nano tube foam metal composite base plate of the invention, compared to answering for other CNT foam metals
Close substrate(Patent CN103434207A), because the adhesion of array carbon nano tube can further fix active material,
With bending resistance, while electrode prepared by array carbon nano tube foam metal composite base plate has well in electrolyte
Stability, it is specific as follows:
Array carbon nano tube foam metal composite base plate has bending resistance because of the adhesion of array carbon nano tube and mechanical performance
Folding endurance energy;
Aforementioned stable refers to the stability of electrode mechanical structure, compared to patent CN103434207A and patent
CN104868134A, array carbon nano tube of the invention, which has, to be sticked and array structure, adhesive attraction can consolidate active material
It is fixed, therefore structure is more firm;
Realize its adhesiveness often by the infiltration of itself and substrate surface different from common adhesion material, CNT with
The adhesion of substrate surface is that realization is brought into close contact with base material roughness at different levels, so as to reach by the flexibility of CNT itself
To adhesiving effect, this is very much like with the hierarchical level absorption in gecko vola;However, with the increase of base surface roughness,
The adhesion on array carbon nano tube and block materials surface will be introduced mechanical sealed due to the increase of contact area, and these are all
To be different under normal temperature merely with the new mechanism of Van der Waals force adhesion;And these are equally applicable to array carbon nano tube and three-dimensional
The research of foam metal.
5th, array carbon nano tube structure(Highly, arrangement degree, caliber, tube wall etc.)It is controllable, can be according to the bubble of different size
Foam metal pointedly carries out the structurally-modified of correlation, regulates and controls height, the caliber of array carbon nano tube structure, density, arrangement degree
Etc. parameter;The array carbon nano tube of Heteroatom doping can be equally prepared before compound, and then carries out the knot of array carbon nano tube
Structure regulates and controls.Further, we can also realize the regulation and control to composite base plate by the regulation and control of the structure to array carbon nano tube, right
Energy field tool is of great significance.
6th, the array structure of array carbon nano tube is easy to cave in, and three-dimensional metal foam structures can fix array carbon and receive
Mitron, so as to play a part of maintaining the stabilization of the array structure of array carbon nano tube.Simultaneously as array carbon nano tube is anti-
Impact capacity can make device have certain shock resistance.
