"Internet red" in the new material world
Graphene is a quasi-two-dimensional material with only one atomic layer thickness. Physicists have long predicted that the thermodynamic properties of the quasitwo-dimensional crystals are unstable, so they cannot exist alone. It was not until 2004 that physicists at the university of Manchester in England separated graphene from graphite, confirming that it could exist alone, and the two men won the 2010 Nobel Prize in physics.
"Much starker choices-and graver consequences-in" graphene industry in-depth analysis and development plan to guide report shows that graphene billed as "the king of the new material", is a kind of two-dimensional cellular materials of pure carbon, set many features at a suit. It is the thinnest and lightest material at present, and it is also the strongest and hardest material. Although the graphite is soft, the single-layer graphene material is even harder than diamond. We know the thermal conductivity of diamond is good, the thermal conductivity is about 2000W/mK (thermal conductivity), and the thermal conductivity of graphene reaches 5300W/mK. Graphene is also flexible and transparent, and only protons can penetrate. These excellent properties have given graphene materials extremely wide application prospects and are the fundamental cause of attracting the world's eyeballs.
Despite the fact that graphene has been "refresh" at the news end, commercial products that really can play its part have been slow to come.
Huawei announced "the high temperature of graphene power lithium ion battery", according to the laboratory chief scientist huawei watt Li Yangxing explanation, high temperature batteries, graphene is plays the role of the efficient heat dissipation, rather than the positive or negative material of the battery. Although it is not a graphene battery, the new battery is capable of killing most of the lithium-ion batteries currently on the market, according to huawei.

The application of graphene industrialization is dawning
After several years of noise, the application of graphene industrialization finally dawned. The China graphene industry association (hereinafter referred to as the "alliance") has awarded the 2016 graphene industry outstanding contribution award to four enterprises. It is the first time the league has awarded the award. Li yichun, general secretary of the alliance, said that the industrialization of graphene is in a critical period, and the award is to encourage industry enterprises to explore and break through in the field of application.
It is understood that one of the conditions of the award is to be the first to develop new applications and have generated sales of more than 20 million yuan.
The four outstanding contribution award for graphene industry enterprises, respectively is: changzhou element 6 new materials co., LTD. (hereinafter referred to as "the sixth element"), hon, dongguan new material technology co., LTD. (hereinafter referred to as "hong recruiting materials"), jinan holy stream technology co., LTD. (hereinafter referred to as the "holy stream technology") and shenzhen ene prosperous new material technology co., LTD. (hereinafter referred to as "ene prosperous new material").
Hongna new material is the first introduction of graphene conductive additive, mainly used in lithium battery positive materials. Although the material has no revolutionary change in the capacity density and charge and discharge rate of lithium battery, it has obvious effect on cost reduction and performance improvement. Because of this, the new products are gradually accepted and purchased in large quantities by the leading companies such as byd, tianjin lishen and guoxuan hi-tech. This also means that graphene has been used in the era of commercialization of lithium. According to the introduction, the annual sales revenue of hongna new material is up to 100 million yuan.
The sixth element, break the foreign monopoly, developed the domestic first graphene heavy anticorrosion coating, and the first industrialization application. It is reported that graphene paint is mainly used in wind power blades, which can be used as anti-corrosion and prolong life, and can be improved by 10 to 20 times. The company is selling 30 million yuan this year, and the company is expanding its production capacity from the current thousand tons to 50,000 tons.
The products of shengquan technology and enwang new materials are mainly used in the fields of textile and clothing, including the annual sales of the graphene underwear of shengquan technology from 50 million to 60 million yuan. Enwang new materials production of graphene heating tablets, and jointly develop new products jointly with more than 10 enterprises downstream, in 2016, the industry chain enterprises are expected to achieve sales of 500 million yuan.
The four companies have been followed by a number of industry imitators. According to the introduction, there are now more than a dozen enterprises producing graphene conductive additives and coatings in China.
According to the introduction, because a large number of enterprises are involved in the industrialization of graphene, the production value of graphene in 2016 is expected to reach 3 billion yuan, far exceeding the 600 million yuan in 2015. Li revealed that many enterprises are trying to industrialize, and in 2017 there will be a total of five or six new industrialization applications. By 2018, the output of graphene is expected to reach 10 billion yuan, and the whole industry will have an explosion year.
