This application discloses a kind of battery graphene complex materials and preparation method thereof, raw material is trimethylolpropane polyoxyethylene polyoxypropylene ether, hydrofluoric acid, nano-silicon, graphite, polytetrafluoroethylene (PTFE), absolute ethyl alcohol, cobalt acid lithium, sodium bicarbonate, titanium dioxide, 1,2 dichloroethanes, potassium nitrate, titanium carbide, acetone, octane, toluene, tetrahydrofuran and ethylenediamine tetra-acetic acid；Simple for process, mild condition, with good electric conductivity, capacity is big, energy density is high, good cycle；Low in raw material price, operation is simple, recycles 300 500 times, capacity 600mAh；Easy to operate, quality and yield are easy to control；Independent of large-scale instrument and equipment, it can be achieved that high quality battery is mass produced with graphene, it can produce extensively and constantly replace current material.
Description
Technical field
The application belong to grapheme material preparation field more particularly to a kind of battery graphene complex material and its
Preparation method.
Background technology
The researcher of nearest Univ California-Los Angeles USA just develops a kind of miniature based on graphene
Ultracapacitor, the capacitor not only low-profile, but also 1000 times that charging rate is common batteries can be in a few seconds
Mobile phone even automobile charging, while can be used for manufacturing the device of small volume.
As presently found most thin, maximum intensity, a kind of strongest novel nano-material of electrical and thermal conductivity performance, graphene
It is referred to as " dark fund ", is " king of new material ", scientist even foretells that graphene " will thoroughly change 21 century ".Very likely lift
Play a subversiveness new technology new industrial revolution have swept the globe.
Actually graphene is inherently present in nature, is only difficult to separate single layer structure.Graphene is folded from level to level
It is exactly hydrofluoric acid to get up, and thick 1 millimeter of hydrofluoric acid comprises about 3,000,000 layer graphenes.Pencil gently streaks on paper, leaves
Trace may be several layers of or even an only layer graphene.
Miniature graphene super capacitor technology breakthrough can be described as bringing revolutionary development to battery.Main manufacture at present
The method of button capacitor is lithographic printing, needs to put into a large amount of manpower and cost, hinders the business application of product.
And common DVD burner is now only needed, and even stay at home, it 30 minutes can be on a CD using cheap material
Manufacture more than 100 miniature graphene super capacitor.
The scientific circles that appear in of graphene have evoked huge great waves.It has been found that graphene has unusual lead
Electrical property, the intensity beyond steel decades of times and fabulous translucency, its appearance are expected to cause in modern electronic technology field
One wheel revolution.In graphene, electronics can be migrated extremely efficiently, and traditional semiconductor and conductor, for example, silicon and copper it is remote
There is no graphene to show well.Due to the collision of electronics and atom, the form of traditional semiconductor and conductor heat releases one
A little energy, general computer chip wastes the electric energy of 72%-81% in this way within 2013, and graphene is then different, its electricity
Sub- energy will not be depleted, this makes it be provided with extraordinary good characteristic.
China also has unique advantage in graphene research, from a manufacturing perspective, as graphene raw materials for production
Hydrofluoric acid, it is abundant in China's energy storage, it is cheap.In addition, mass production and large scale production are to hinder graphene extensive
Commercial main factor.And the newest achievement in research in China has successfully broken through this two hang-up, manufacturing cost from 5000 yuan/
Gram 3 yuan/gram are down to, solve the volume production problem of this material.It is successfully manufactured that using chemical vapour deposition technique first domestic
15 inches of single-layer graphene, and successfully graphene transparent electrode is applied on electric resistance touch screen, prepare 7 inches of stones
Black alkene touch screen.
The application prospect of graphene is exactly seen, many countries establish graphene the relevant technologies research and development centre one after another, taste
Examination is commercialized using graphene, and then is obtained in industry, technology and electronic correlation field and potentially applied patent.EU Committee
Using graphene as " the following emerging flagship technological project ", special research and development plan is set up, 1,000,000,000 Euros of warps are transferred in coming 10 years
Take.British government also invests in national graphene research institute (NGI), tries hard to make this material can be from coming few decades
Laboratory enters production line and market.
Chinese graphene industrial technology innovation strategic alliances lead Bei Terui, Zheng Tai group, Changzhou hexa-atomic element, yiyang collection
Hispanic graphene meeting has been participated in the representative of Tuan Dengsijia listed companies, and is signed respectively with Italy, delegation of Sweden
Depth strategic cooperation agreement, for " the graphene whole world is merged, and China integrates ", the first shot was fired for strategy.In addition, global at the beginning of 3 months
First batch of 30,000 volume production graphene mobile phones are issued in Chongqing, open the new era of graphene commercial application.Graphene is selected
The planning of " 13 " new material makes a decision substantially, it is contemplated that will become within 2015 Chinese graphene industry and break out the first year, with society
Can urbanization, technicalization, hommization development, design is a kind of to be not easy to be destroyed, yield is high and the battery that is produced on a large scale is used
Graphene complex material and preparation method thereof, it is of low cost, to meet the market demand, it is very important.
Graphenano companies of Spain (company for producing graphene on an industrial scale) are the same as more than Spain Cole watt
University's joint study goes out the first graphene polymeric material battery, and reserve of electricity is three times of the best product of existing market, with this electricity
The electric vehicle most multipotency that pond provides electric power travels 1000 kilometers, and its charging time was less than 8 minutes.Although this battery has various
Excellent performance, but its cost is not high.Graphenano companies relevant person in charge claims, and the cost of this battery will be lower than lithium battery
77%, completely within consumer's tolerance range.In addition, in fields such as automotive fuel cells, graphene is expected to bring revolutionary character
Progress.
