“China has become the global leader in the commercialization of graphene, and the development of graphene for the industrial sector is basically all in China. In terms of the global situation, the industry leader is in China and R&D is leading in Europe.†China Graphene Industry Technology Innovation Strategic Alliance The Secretary-General Li Yichun set the Chinese graphene industry so precisely at the 2017 China International Graphene Innovation Conference held recently.
As a vane for the development of graphene, China International Graphene Innovation Conference reflects the industrial development of graphene. Many experts, scholars, and entrepreneurs believe that the biggest difference between this year and previous years is that a group of companies have begun to sink their hearts, push forward the market, and make practical applications. Investors also tend to be rational and “less speculative, There are many product applications."
“A big change this year is that the market is becoming mature and rational. Now there are companies in the industry who are listed on the main board and they are diving in this field. They are very low-key.†Chairman of the Graphene Industry Technology Innovation Strategic Alliance of Jiangsu Province, Changzhou Six element general manager Yan Yan said.
Industrial development boom unabated
China is one of the most active countries in the global research and application of graphene. Statistics show that in 2016, the overall scale of the graphene market in China exceeded 4 billion yuan, and sales of graphene-related products reached about 3 billion yuan. According to the prediction of the China Graphene Industry Technology Innovation Strategic Alliance, the graphene market in China will expand rapidly in 2017 and is expected to exceed 10 billion yuan, becoming the world's largest consumer of graphene.
At the same time, China is also leading the industrialization of graphene materials. The “ene making movement†has spread all over the country. Local governments have launched various graphene research institutes and industrial parks. According to incomplete statistics, there are currently more than 300 companies engaged in the development of graphene products and production equipment. There are 20 graphene research institutes or industrial bases under construction or completed throughout the country.
“Currently, when the graphene is truly the leader or is still in progress, the industry is still in the running phase. With the advancement of industrialization, some companies will be eliminated. But this is a normal phenomenon of industrial development, the industry will be in the survival of the fittest. Develop and grow.†Li Yichun’s views are quite representative.
The industry generally believes that industry consolidation under the market mechanism will accelerate, and companies with strong technical strength, well-funded, and guaranteed quality will eventually come to the fore. “There will be a big shuffle in this industry. After the big waves break, the graphene industry can really thrive and move into a healthy development track.†Yan Yan said.
Application promotion blocked
However, graphene seems to be blooming, but it is facing the biggest bottleneck in application. According to Yan Yan, graphene production capacity is currently sufficient, but the application market is not fully open, there is a mismatch between supply and demand. The personage inside course of study shows, the problem that the graphene faces at present is not the overcapacity, but the applied market has not been opened yet, "finding the most cost-effective place to expand the batch application of graphene is the matter of top priority."
“The industrialization of graphene is difficult to promote, and various frustrations will be encountered during this period.†Wang Zhonghui, deputy general manager of Dongxu Optoelectronics and person in charge of graphene, stated that Dongxu Optoelectronics launched its graphene-based lithium-ion battery “Alken "When doing marketing with customers, customers are particularly cautious about the products, and they need to be gradually introduced in the interaction with customers, and they will not be able to quickly increase sales volume."
For the graphene industry, which is still in its infancy and still in its infancy, the industry believes that there is a process for downstream companies to accept, and they must have enough patience to allow sufficient time for cultivation.
“At present, Dongxu invests no less than 500 million yuan in the field of graphene, and is actively constructing its own ecosystem. First, it is a closed loop from the graphene-based lithium-ion battery to the new energy automobile industry. One is the high power of graphene heat dissipation. The LED lighting series is a smart city based on the core.†Wang Zhonghui introduced the long-term plan for the development of Dongxu's graphene industry chain.
In the expansion of the application market, Yan Yan added that in addition to the company’s efforts to promote the market, the government must also play a guiding role. “At the beginning, it is necessary to push forward, such as the first set of projects, demonstration projects, etc., and the government should create new ones. Product innovation environment."
Urgently open the market for power battery applications
As an "industrial monosodium glutamate," graphene can be used in a wide range of applications, including lithium battery conductive additives, super capacitors, anti-corrosion coatings, electric heating and health equipment, touch screens, and seawater desalination. Currently, the most widely used is a lithium battery conductive additive. .
“The conductive properties of graphene additives are mainly reflected in two aspects. One is to reduce the amount compared to traditional conductive agents, and the second is to increase the proportion of active materials in the battery, thereby increasing the energy density of the battery.†General Manager of Hongna New Materials Xiao Feng explained, “At present, many power battery manufacturers use carbon nanotubes and graphene composite conductive agents to better improve battery performance.â€
At present, China vigorously develops new energy vehicles and proposes that the number of new energy vehicles will reach 5 million by 2020. As the driving force of new energy vehicles, the battery has also witnessed rapid development. Some agencies predict that the demand for power lithium batteries will reach 120gmh by 2020. This news brought good news to the development of graphene conductive additives.
Xiao Xiaoyue, chairman of Nanjing Corfu Nano Co., Ltd., said that graphene conductive additives have considerable advantages in terms of electrical conductivity and resistance to resiliency. With the expansion of China's lithium industry, more and more lithium manufacturers will use graphite. Alkenes replace traditional carbon nanotubes.
According to Xiao Feng, since the completion and production of the world's first 10,000-ton graphene production line for the research and construction of Hongna New Materials in 2014, the production capacity has continued to expand. By the end of this year, graphene slurry production capacity will reach 15,000 tons.
Hongna's expansion plan for new materials is only a microcosm of the development of the entire graphene industry, and many companies are also eyeing this market, and production capacity is continuously spreading. For example, Xinao Group has already put into operation a demonstration device for 100-ton graphene powder materials in Langfang, and is constructing a large-scale conductive paste production line. It plans to build a large-scale production of graphene powder and conductive paste in Erdos, Inner Mongolia. base.
“Our output can be 50-100 tons a year. There is no problem in expanding production capacity. The key is market development. The replacement of battery materials by power battery manufacturers must undergo rigorous testing, and various verifications will be introduced into the production line. This requires For a relatively long period, we are currently in the sample delivery testing stage, said Cao Dianxue, general manager of Heilongjiang Huasheng Graphite Company.
In Xiao Feng's opinion, the current graphene industry is in the “darkness before the dawn†and there are two breakthroughs: one is the lithium battery conductive additive and the other is the fireproof coating. “If these two markets are opened, the company can survive. â€
In addition, many experts and scholars believe that China's graphene companies should look to high-end R & D, fine research and development. Liu Zhongfan, an academician of the Chinese Academy of Sciences, suggested that several high-end R&D institutions facing the future graphene industry should be established to focus on stable support; the government should clearly define the decision-making position, lay stress on the layout of the future core technology of the graphene industry, and give low-end products to the market and let go. enterprise. “The government must seize the layout of the future. In fact, the government can only do the layout of the environment.
