Development status, main problems and suggestions of China's graphene industry

as China's economic development and growth enter the "new normal", economic growth slows down, and downward pressure exceeds people's expectations. In order to enable China's economy to develop steadily in the "new normal" period and fight a decisive battle to achieve a well-off society in an all-round way, a new economic driving force is indispensable. The introduction of a series of major policies such as made in China 2025, several opinions on accelerating the innovative development of graphene industry and the 13th five year plan has determined the leading position of China's manufacturing industry in promoting economic development in the "new normal" period in a new era with high added value based on the transformation and upgrading of traditional industries. Scientific and technological innovation and new materials are indispensable supporting forces to achieve the great goal of made in China in the new era. Graphene, as the brightest pearl on the "crown of materials" in the 21st century, will certainly point out the way forward for China's scientific and technological innovation in the new era and become one of the most powerful focus of made in China

I. Development of graphene industry in China

with the promotion of graphene industrialization, the proportion of small enterprises increased in 2015 compared with 2014, and the large-scale development of medium-sized enterprises strengthened. By the end of December 2015, the number of enterprises engaged in graphene R & D, production, sales, promotion and other related enterprises in China has reached more than 300, of which 100 enterprises have graphene related products on sale. The number of listed companies mainly engaged in graphene increased from 1 in 2014 to 4, and the number of related listed companies with graphene layout reached more than 10. In 2015, as the first year of the graphene industry, the overall revenue of the domestic industry reached 600million yuan, an increase of more than 10 times compared with 2014

1. Development of regional graphene industry

with the implementation of the spirit of the document "several opinions on accelerating the innovative development of graphene industry" (hereinafter referred to as "opinions") issued by the three ministries and commissions by local governments, the distribution of graphene enterprises in China has expanded from the southeast coastal region to the entire eastern coastal region in 2015, and gradually expanded to the west, with the distribution of graphene enterprises showing the characteristics of "vertical and horizontal distribution"

(1) the Yangtze River Delta region

the Yangtze River Delta region is an area where graphene developed earlier in China and the domestic graphene industry chain is relatively perfect. In 2015, there were more than 170 graphene enterprises in the Yangtze River Delta, with an overall revenue of 350million yuan, accounting for 58% of the overall revenue of the graphene industry in China. Among them, Changzhou sixth element material technology Co., Ltd. and Changzhou two-dimensional Carbon Technology Co., Ltd., two companies mainly engaged in graphene, are listed on the new third board. On the whole, the whole Yangtze River Delta region accounts for half of China's graphene industry. Relying on the local good industrial development platform and perfect industrial development system, the region has formed a comprehensive industrial development model covering graphene preparation, new energy, composite materials, thermal management and other fields. This industry development model has played a good role in demonstrating, driving and radiating the development of graphene industry all over the country

the Pearl River Delta region is a very active region in the development of China's graphene industry. In 2015, more than 60 graphene enterprises were developed in the region, with an overall revenue of 100million yuan, accounting for 17% of the overall revenue of the national graphene industry. In July 2015, Shenzhen advanced graphene Application Technology Research Institute was initiated by China graphene industry technology innovation strategic alliance, China Baoan Group Co., Ltd., Southern University of science and technology, Tsinghua University and Shenzhen Research Institute of Peking University. It is the only professional research institute for graphene application approved by Shenzhen at present. On the whole, the Pearl River Delta region is an extremely active region in China's graphene industry, and it is also one of the regions where the downstream application market of graphene has been developed rapidly. It has formed an industrial development model based on graphene production and equipment manufacturing, focusing on breakthroughs in new energy, great health, electric heating, composite materials and other fields, and has played a positive exemplary role in the development of the downstream application market of the national graphene industry

2. Development of graphene products

in 2015, China's graphene industry made breakthrough progress, the upstream and downstream industrial chains have been basically opened up, and the downstream application fields have been gradually expanded. By the end of 2015, China's graphene industry has formed six major market-oriented fields, mainly including new energy, great health, energy conservation and environmental protection, composites, graphene raw materials and graphene equipment

(1) development of graphene in the field of new energy

II. Main problems in the development of China's graphene industry

although China's graphene industry has made great progress in 2015, the graphene industry is still in the primary stage and faces many problems that need to be solved in the process of industrialization development

1. R & D in production and application lags behind

at present, most domestic enterprises involved in graphene production and application development are small and medium-sized enterprises and start-ups. Although some large private enterprises, state-owned enterprises and central enterprises have begun to pay attention to graphene, most of them have not made substantive investment. Therefore, the high-tech level, low-cost preparation technology and industrial application development have not yet achieved, so the substantive breakthrough is selected according to the maximum value

2. Lack of guidance in industrial application technology

although the graphene industry has a huge scale, the downstream application market needs to be developed urgently. At present, the transformation from R & D to application is slow, and the channels are not smooth. Relevant large enterprises lack their own R & D investment in graphene technology and the motivation to choose graphene in terms of product component materials. In this regard, more guidance and promotion are still needed

3. the market demand has not been fully opened

at present, there are hundreds of units engaged in graphene production and R & D in China. Although most enterprises have basic design and production capacity, the product differentiation is small. Although the output of graphene is increasing year by year, due to the lack of breakthrough in downstream applications, graphene has no market. If we only increase the output of graphene instead of expanding the downstream application of graphene according to the existing products, the industrial chain of graphene will not be formed, and the graphene industry will be difficult to achieve the expected scale

4. Irrational prosperity of the capital market

at present, graphene and its related industries have increasingly become a hot concept in the capital market, but at present, graphene related products are confused in the market, and the phenomenon of uneven product quality is very serious. Some graphene enterprises do not have the relevant technology and large-scale production capacity to produce graphene at all. Such excessive publicity will weaken the trust of application enterprises in the quality of domestic graphene, and then hinder the development of China's graphene industry

III. suggestions for the development of China's graphene industry

1. increase investment in downstream application research and development, and start the application demonstration project
