Description
Technical field
The invention belongs to the preparation field of flexible electrode, more particularly to a kind of preparation method of carbon-based flexible electrode.
Background technology
Direction with electronic product towards intelligence, micromation and portability is developed, and there is an urgent need for develop matching height
The flexible energy storage device of effect.Ultracapacitor is since power density is high, have extended cycle life, safety non-pollution, is easily achieved its flexibility
The features such as change, causes the extensive concern of people in recent years.Grapheme material has high specific surface area, excellent electrochemistry
It can be widely used as the electrode material of flexible all-solid-state supercapacitor with good mechanical stability.And it is traditional planar
Ultracapacitor usually requires metal as charge collector, and electrode is to mix active material with binder, conductive additive
It is coated on collector and is made afterwards.Although powdered active material is loaded to by modes such as simple hot pressing, coating, stickups
On carbon-based material, but the use of non-conductive binder, the reunion of active material, more closely knit structure and electrode are folding
Or it easy tos produce and falls off or dusting all can cause the chemical property of final product to perform poor, Bu Nengman in the case of bending
The demand of sufficient flexible electronic device.
Flexible carbon electrode material such as carbon cloth etc., due to its relative low price, conduct electricity very well and chemical stability it is high and
It receives much attention.The memory mechanism of carbon material is electric double layer capacitance, ionic adsorption and charge by the interface of electrode and electrolyte
Energy storage is realized in storage.But because of surface chemistry inertia, duct can not pass the business carbon cloth or business carbon felt not being activated
Defeated electrolyte ion often has the area specific capacitance (carbon cloth of commercialization is only 1~2 millifarad the/square centimeter) of very little,
The requirement of practical application cannot be met.Therefore, how to design synthesis has high specific surface area active, the multi-stage porous knot of perforation
Structure, it is the emphasis studied effectively to regulate and control the functional group of carbon material surface and the carbon-based electrode material of excellent properties.Specially such as China
Sharp [105869923 A of CN], [104201006 B of CN] are by modes such as high-temperature exercise, plasma chemical depositions to carbon cloth
It is surface-treated, but processing procedure needs inert gas shielding and to equipment requirement height；The introducing of a large amount of oxygen atoms is although right
The energy storage capacity of carbon material is promoted, but the conductivity that carbon material is substantially reduced limits its final chemical property.And
Using etching modes such as acid processing by carbon material Cavitated, although specific surface area increases, the originally excellent mechanics of carbon material
Degradation.It more commonly will be with the graphene compared with high electrochemical activity, carbon nanometer by the modes such as depositing, coating
Pipe, active carbon black etc. are combined on two-dimensional flexible carbon-based material, constitute three-dimensional structure to increase specific surface area, two-dimensional flexibility
Carbon-based material mainly plays a part of support and conductive base.As Chinese patent [1000358803 C of CN] passes through vapor deposition

New environmental hazard will be brought by closing the use of hydrazine；Graphene powder is passed through electrochemistry by Chinese patent [104947134 B of CN]
Deposition method has obtained the carbon cloth electrode of porous graphene modification to carbon cloth surfaces, since graphene powder needs individually system
Standby, effective electrochemistry that inevasible agglomeration reduces graphene utilizes area.
Graphene is a kind of known most thin material, and with high specific surface area, superpower electric conductivity and strong
The advantages that spending due to that can promote existing equipment performance, and keeps next-generation equipment more practical, and graphene-based material is counted as foreground
Far-reaching high performance electrode material possesses good market prospects.Graphene generally use oxidation-reduction method or physics stripping, height
Temperature expansion the methods of graphite oxide powder is removed, be made graphene oxide, then by chemical method by graphene oxide also
Original obtains graphene.Chemical method is easy to operate, and yield is high, but product quality is relatively low, is often used the strong acid such as sulfuric acid, nitric acid,
There are larger danger, and must be cleaned using a large amount of water, and larger environmental pollution is brought.In view of graphene is easy
Reunite, is usually all to use preceding ability redox graphene, and graphene oxide contains more rich oxygen-containing functional group, is easy to
It is modified；It can constantly be restored under the influence of the external agents such as high temperature in compartment in sunlight, transport, it is more difficult to stone after control reduction
The graphene of the oxygen content of black alkene, the production of simultaneous oxidation reduction method is often inconsistent by the quality of batch product, it is difficult to Control platform,
The reliability and its practical application of ultracapacitor are seriously affected.Therefore the uniform, property with structure how is prepared to serialization
Graphene macroscopic view assembly needs that can be stably and controllable are paid close attention to and are solved.That is utilize two-dimensional layered structure that can build
Go out various three-dimensional structures, overcome the problems, such as that graphene film interlayer is stacked with, improves effective electrochemistry profit of graphene-based electrode
It is to excavate great potential of the graphene in the application of future source of energy storage device to need urgent problem to be solved with area.
