There is a new material that can develop a new battery that can compress hours of charging time to just one minute. This new material is graphene.
Graphene is a two-dimensional crystal with only one layer of atomic thickness, which is separated from the graphite material and composed of carbon atoms. As a new type of nanomaterial that is currently found to be the thinnest, strongest, and most conductive and thermally conductive, graphene is called "black gold" and is the "king of new materials." Scientists even predict that graphene will "completely change the 21st century." "It is very possible to set off a revolutionary new technology and new industrial revolution that has swept the world."
In Sichuan, there are 80 million tons of proven graphite mines in the province, accounting for 40% of the country. Rich resources, good prospects, is it a true portrayal of the graphene industry in Sichuan?
The optimism of the various capitals makes the academics’ years of loneliness and hardship become more and more deserted.
Fired graphene
On March 29, Chengdu Institute of Organic Chemistry, Chinese Academy of Sciences, No. 16 South Section 2, First Ring Road, Chengdu. "He is coming again in the afternoon." Yan Meizhen is the director of the Research and Development Center of Catalytic Technology of the Institute. He is the chairman of a certain technology company in Chengdu. The two have recently met frequently because the other party has taken a fancy to the "baby" in the hands of 瞿美臻 - graphene.
In 2009, Yan Meijun's team began the development of graphene preparation. In 2011, the laboratory successfully prepared graphene. Today, only laboratory equipment can produce hundreds of kilograms of graphene nanosheets per day, as well as 1 kilogram of single-layer graphene powder. A pilot production line of 10 tons/year of graphene conductive powder has been opened and is scheduled to be produced at the end of June. “Real industrial production is about to be realized.†Yan Meijun said that this is also an important reason for companies to find him frequently. “I want to cooperate and want to invest money.†I have counted the number of people, and I have come to seek cooperation for a short period of one month. There are seven or eight investment companies, including many well-known listed companies.
After years of loneliness and hard work, nowadays, it seems that Mei Meizhen feels the "incitement" of graphene overnight.
On the afternoon of March 3, Sichuan Graphene Industry Technology Innovation Alliance was established in Deyang City. The chairman of the alliance is Guo Anxian, chairman of Deyangene Carbon Technology Co., Ltd., which has been engaged in the production and development of graphene. Deyangene Carbon Technology has built a 1.5-ton pilot production line of graphene powder and slurry in 2012. In April, an annual production capacity of 30 tons of graphene powder production line will also be commissioned.
On the same day, more than 10 companies were present, and information related to graphene was also gathered here: Deyang set up the first graphene industry fund, Suining was developing graphene conductive paste, Panzhihua accelerated the establishment of graphene engineering technology research center, Bazhong Graphite resources will accelerate mining... Many entrepreneurs even know that Sichuan Province has already accelerated the preparation of the graphene industry development plan into the important work of the government. “New materials often bring revolutionary changes. The superior performance of graphene has enabled the industry to quickly smell its potential applications in electronics, aerospace, biotechnology, new energy, semiconductors, etc.†Li Xuesong, the national expert on the “Thousands of Young People†– the world’s first scientist to invent a large-scale preparation of graphene film. In July last year, he returned from the United States and went to teach at the University of Electronic Science and Technology. He told reporters that there is a clear literature that the inclusion of one percent of graphene in plastics can make plastics have good electrical conductivity; adding one-thousandth of graphene can increase the heat resistance of plastics by 30 degrees Celsius. . “Sichuan’s graphite resources are very abundant and have a good foundation for the development of graphene industry.†Such discourses are frequently heard in government, enterprises and experts. Bazhong, Panzhihua and other places have abundant graphite resources. The province has 80 million tons of graphite mines, accounting for 40% of the country. It is also reasonable to vigorously develop the graphene industry with promising prospects.
The industry standard is missing, the cost is high, and the downstream industry chain has not yet formed.
Broken graphene
"For more than 10 years, this mine has repeatedly restarted work and stopped working. I don't know if this plate can be completed." Recently, Bazhong Nanjiang County, Pinghe 100,000 tons / year high carbon graphite mining and selection project started, surrounded by watching lively Among the crowds, some villagers said this.
As early as 2000, the Pinghe graphite mine in Nanjiang County obtained a mining license and a small amount of mining. But how the graphite mine is processed and used, but the people in the mountains are at a loss. In the meantime, due to the single structure of low-carbon graphite products and low technical content, mining on the mine has been repeated many times.
Now that the graphene industry is hot, Bazhong decided to start graphite mining again. This time, the local not only set up a leading group for the development of the graphite industry, but also formulated the “Basic Industry Development Plan for Bazhong Cityâ€, aiming at the development of high-tech graphite industry, and the finger refers to graphene.
