At the moment, there is a view that graphene's ongoing fever in China is overdone.In the view of zhao meng, deputy secretary general of the China international graphene industrial resources alliance, the market decides whether graphene should continue to be "hot" or "reduce the fever".He believes that from the market point of view, the graphene industry in China is far from "hot" enough to "reduce the fever", and should continue to "hot".
Graphene is an allotrope of carbon in the form of a single layer of atoms in a two-dimensional hexagonal lattice in which one atom forms each vertex. It is the basic structural element of other allotropes, including graphite, charcoal, carbon nanotubes and fullerenes.
The development momentum of graphene industry is good.
China economic times: it is learned that the country attaches great importance to the graphene industry.President xi jinping visited jiangsu graphene materials research institute in 2014, visited the graphene research institute of the university of Manchester in the UK in 2015, and visited the graphene technology exhibition in Harbin in 2016.At present, what is the overall level of graphene industry in China?
At present, China's graphene industry has been in a leading position, showing a pattern of ten thousand enterprises' innovation and competition. According to the latest statistics of in-depth market research and strategic planning analysis report on graphene industry released by qianzhan industry research institute, the graphene market in China is expected to reach 56 billion yuan in 2019 and 236.5 billion yuan in 2022.
Three major weaknesses need to be overcome.
China economic times: in your opinion, what are the weaknesses of China's graphene industry that need to be overcome?
Zhao meng: there are still many shortcomings in the development of graphene industry in China, and the following three aspects should be given priority.
First, resource imbalance.For example, China's Yangtze river delta, guangdong-hong kong-macao greater bay area and beijing-tianjin-hebei region have advantages in talent, technology and capital. Their technology has been upgraded rapidly, but their environmental capacity is small and there are few graphite resources that can be developed.However, the three northeastern provinces, sichuan and chongqing, and the central and western regions have advantages of large environmental capacity and rich graphite resources, but lack of talents, technology and funds.How to guide the division of labor and cooperation from the national level, optimize the allocation of resources, industrial layout remains to be studied.
Second, there is little international cooperation.In recent years, there have been more and more exhibitions and BBS at different levels in China, and some regions or enterprises have introduced talents and technologies. However, the speed and efficiency of the promotion are not fast enough, and the scope and level of cooperation need to be improved.Special attention should be paid to the cultivation, exchange and cooperation of international talents.
Third, industry standards are lagging behind.We should not only promote the formulation of national standards, but also promote the formulation of international standards and strive for a voice.
The current technique of graphene materials smartphone, charge and discharge rate to 40%, higher than that of traditional smartphone even so fast, still not achieve the ideal effect of graphene materials, this is huawei said Mate20 series as the cause of graphene based battery, the flexible screen smartphone will also depend on the application of graphene technology.
At present, battery technology is a huge obstacle to the promotion and development of electric vehicles. If graphene energy storage equipment is successfully developed out of the laboratory and mass produced, it will bring revolutionary changes to the battery industry and even the electric vehicle industry.However, graphene battery technology still faces the problem of high cost before it can go from experimental stage to mass production stage. The optimistic forecast is that large-scale commercial use may be beyond 2020.
