The Graphene Industry Fund, with a scale of 20 billion yuan, was formally launched in Nanjing. The fund uses "capital + industry" as the core to build a graphene ecosystem, aiming to solve the problems faced by the development of graphene industry and help innovation and development.

“In fact, at present, no more than five companies in China have truly taken graphene as a growth point and put out hundreds of millions of dollars for their distribution. There are companies that are really dry, fake, and hype.” Secretary of the China Strategic Alliance for Graphene Industry Technology Innovation Li Yichun admitted in an interview with a reporter from the China Business News that the alliance encourages companies with capital and industry strength to invest in the graphene industry, and more emphasis on corporate investment, rather than investing only in graphene projects.

Li Yichun believes that investment industry and investment projects are not the same. The graphene market is a mixed bag and should condemn the speculative mentality of some companies speculating on the concept of graphene. At the same time, he said that the key to restricting the industrialization of graphene lies in its application.

The layout of the company is uneven

Graphene is a two-dimensional crystal that is stripped from graphite, composed of carbon atoms, and has only one layer of atom thickness. Its natural properties are the thinnest and most powerful materials known to date in the world, with excellent electrical conductivity, thermal conductivity and light transmission.

According to industry insiders, after the conception and productization of graphene, the formal vector production road has progressed, and this year's performance has been particularly pronounced.

The reporter noted that some domestic companies have frequently moved to accelerate the layout of the graphene industry. For example, Dongxu Optoelectronics (11.160, 0.01, 0.09%), Rongqi Group (14.980, 0.10, 0.67%), Del Future (15.230, 0.10, 0.66%), the gorgeous family (7.710, 0.03, 0.39%), Baotailong (11.120, 0.43, 4.02%) and other listed companies have entered the graphene sector through acquisitions, shares, and other forms.

Among them, Dongxu Optoelectronics (000413.SZ) officially released the world's first graphene-based lithium-ion battery products in 2016. Since then, the company has successively completed the closed-loop path of the complete industrial chain of graphene-graphene-coated lithium iron phosphate cathode material-graphene-based lithium-ion battery-new energy vehicle.

On October 11, Dongxu Optoelectronics also announced that it intends to cooperate with the University of New South Wales on the development of high-performance, high-conductivity bucky paper and graphene paper, graphene composite super desiccant, and high energy density supercapacitors. Strategic cooperation.

Dongxu Optoelectronics deputy general manager Wang Chenghui, the person in charge of graphene business, told reporters that Dongxu Optoelectronics has created two ecosystems in the field of graphene applications. One is the closed-loop industrial chain from a graphene-based lithium-ion battery to a new energy vehicle. One is a smart city based on new products of graphene heat dissipation and high power LED lighting.

Li Yichun believes that the continuous development of Dongxu Optoelectronics in the field of graphene, including international cooperation and industrialization, is indeed playing a leading role in the industry. Now Dongxu Optoelectronics has successively cast some graphene projects. Its graphene technology content is relatively high and has a high threshold.

However, Li Yichun also stressed that "the current domestic graphene products are mixed. In contrast to the above, some companies in the industry are speculating on the concept of graphene, and there is speculative psychology in the market." Li Yichun believes that, in fact, currently No more than five companies in China have really taken graphene as a growth point and put out hundreds of millions of dollars for the layout.

Researcher Puhua Researcher Jie Xiaolan also told reporters: “At present, the entire industry chain of graphene industry has taken initial shape, covering all aspects from raw materials, preparation, product development and downstream applications. However, due to the small number of leading enterprises, the scale Relatively small, it restricts the further development and improvement of the entire industrial ecosystem."

Industrial chain layout needs to be improved

Jie Xiaolan told reporters that it is estimated that China’s proven reserves of graphite ore have reached more than 75% of the world’s total. Up to now, the number of graphene patents in China ranks first in the world, and the number of academic papers on graphene published by China ranks first in the world. At present, more than 500 companies across the country have launched graphene-related businesses, which have formed large-scale advantages in terms of scale and quantity. At present, the industrialization of graphene in China is one of the best in the world, and it is in a leading position in the world, mainly because it is rapidly promoting the upgrading of manufacturing industries.

Although China's graphene research started relatively late, its development speed is fast and its potential advantages are obvious. In recent years, the number of domestic related patent applications and applicants has grown very rapidly, and the technical topics involved have become more extensive. Jiangsu, Chongqing, Shenzhen, Heilongjiang and the Chinese Academy of Sciences and other provinces and cities cooperated and innovated in various forms and established industrial technology alliances one after another, which promoted the optimization of innovation resources and the industrialization of innovation.

According to statistics from the Graphene Industry Alliance of China, as of 2016, the number of graphene patents in China accounted for 58% of the total number of major priority patent applications in the world; among the top ten global graphene patent application organizations, Zhejiang University, Tsinghua University, etc. Five Chinese universities were nominated. It can be seen that the current research and development level of graphene in China has been in a relatively leading position in the world.

Jie Xiaolan said that with the continuous introduction of relevant policies, as well as the continuous construction of industrial alliances and innovation platforms, it is expected that the layout of the graphene industry chain will be more perfect in 2018. It is expected that the graphene industry will shake the trillion industrial chain by 2020.

Xiao Jinsong, director of the Institute of Raw Materials Industry of the Institute of Industry and Information Technology, told reporters that the graphene industry is expected to enter a stage of maturity from 2021 to 2035, and that it will be able to use high-end devices and products with unique graphene advantages. Industrialization, such as graphene terahertz detectors, biosensors, seawater desalination filters, laser emitters, and integrated circuits.

However, as an emerging industry, graphene industrialization process still has many shortcomings. The graphene industrial chain is also extremely weak, and it does not form a complete and mature industrial chain. Upstream and downstream, graphene R&D and production companies and downstream application companies are the main features. In addition, due to the lack of downstream demand, most graphene companies are still unable to find a stable business model and profit model.

Li Yichun believes that the key problem facing the graphene industry today lies in its application. “From the whole industry, the mass production technology of graphene production has been opened up, and it needs to be optimized. But how can we optimize it without application? The products produced by enterprises cannot be sold, and which companies are willing to produce, 100 tons and 200 tons, Where to put it, the cost is too high, which requires application pull, continuous optimization, and the promotion of a strong combination of supply and demand."

"Although China's graphite ore reserves account for more than 70% of world reserves, it faces a small and scattered situation; there are still technical bottlenecks in the midstream preparation process, and stability and mass production cannot be guaranteed; downstream application development is ineffective and the cost is high and hinders the downstream. Application development." Jie Xiaolan said that we should strengthen the planning and policy guidance of graphene industry, promote the coordinated development of graphene material research and development, production and application; guide leading enterprises to integrate the innovative forces of universities, institutions and characteristic SMEs, and collaboratively tackle problems. The key technologies and complete sets of equipment for large-scale production of graphene materials will be broken through as soon as possible, and the factors such as application difficulty, downstream affordability, and potential application scale of graphene will be co-ordinated and steadily promote the market development of graphene material applications.
