Graphite has always been an indispensable strategic resource for military and modern industries and for the development of high, new and cutting-edge technologies. The province's graphite reserves rank first in the country. With its rich graphite resources, large reserves and high grades, it has become an important production base for graphite products in China and the world.

However, the technical level of the graphite industry in our province is low, and the lack of strong support for downstream high-tech products has become a bottleneck in the development of the graphite industry. Vigorously carry out in-depth research on graphite foundation and cutting-edge technology, realize major original innovation of high-end graphite core technology, realize high-efficiency conversion and application of scientific and technological achievements through deep integration of production, study and research, promote the deep processing of graphite and its high-end application technology and industry development, Creating an internationally competitive high-end graphite application industry has become an urgent need in our province and even the whole country.

Concentrate on scientific research and aim at practice
The reporter recently came to the Harbin Institute of Technology graphite deep processing and high-end application research center. According to the director of the center, dean of the School of Chemical Engineering of Harbin Institute of Technology, and Changjiang Scholar Huang Yudong, the center has 44 members, including 2 special professors of Changjiang Scholars. There are 1 youth fund winner, 1 youth camp planner, 7 new talents in the new century and 7 provinces in the province. The team members have a strong cross-disciplinary background, and the research direction covers professional fields such as materials science, chemical engineering, and environmental engineering.

Professor Huang Yudong said: "The Research Center for New Technology and High-end Application Engineering Technology of Graphite Processing is the provincial engineering technology center approved in September 2013. The center combines the research and development and industrialization status of natural graphite and related industries in our province and natural graphite minerals. The overall development plan of resources, through the advanced, efficient, environmentally friendly, low-energy natural graphite deep processing key technology and industrialization research, develop the key core technology of natural graphite deep processing industry with independent intellectual property rights, improve the deep processing level of the natural graphite industry in our province, and form Our province's graphite deep processing and high-end application technology industry chain."

The reporter learned that the Graphite Center has formed an innovative test covering four first-level national key disciplines, one national laboratory, two national key laboratories, two provincial-level laboratories, and one national engineering center. The platform embodies dozens of high-end technical talents and several high-level innovation teams including academicians, Changjiang scholars and Jieqing.

Since its operation, Graphite Center has fully participated in the national and provincial science and technology major and key projects in the graphite field, and has broken through a number of core key technologies, providing a number of cutting-edge technology reserves based on basic theoretical research for the development of high-end graphite applications in China. At present, the graphite center has become an important base for the development of graphite in China.

Connected companies release energy
Professor Huang Yudong said: "Harbin Institute of Technology has many years of research in the frontier of natural graphite deep processing and high-end applications. In order to further pool the superior resources and provide innovative source of high-end applications for graphite in Heilongjiang Province, Harbin Institute of Technology collaborates with chemical and chemical materials, materials, The comprehensive advantages of various disciplines such as environment and physics, and active cooperation with Bethray New Energy Materials Co., Ltd. and Aoyu Graphite Group in the field of graphite battery materials. The negative electrode materials developed in cooperation with Betray have been successfully applied to Tesla. Car battery."

It is understood that the focus of the center is the large-scale preparation technology of graphene and graphite paper, batch preparation of modified natural graphite battery materials and battery manufacturing, high flame retardant natural graphite, key technologies for polymer material preparation, expanded graphite and products. Development and application of graphite-based functional coatings.

Based on the above research directions, the center has made great achievements in scientific research, technology transformation, and industrialization. The cooperation has undertaken a number of national, provincial and ministerial major research projects, such as the National Science and Technology Support Program, the National 863 Program, the Major Project of Electric Vehicles, the International Cooperation Project of the Ministry of Science and Technology, and the Major Project of the Provincial Applied Development Science and Technology Program.

Graphite Center has also established long-term cooperation with Harbin Coslight Power Co., Ltd. in our province in the field of high-capacity anode and high-performance battery manufacturing, and established a stable and long-term cooperation mechanism for production, education and research, and developed high-performance graphite/silicon anode materials. Successful application of battery products, battery energy density increased by 20% compared with conventional batteries.

Innovative "drums" moved. To create a multi-disciplinary and collaborative high-level scientific research team, Harbin Institute of Technology graphite deep processing and high-end application research center is forming a "domestic first-class, internationally renowned" research and innovation platform and subject group of high-end graphite applications, and build a leading talent training system for high-end applications in graphite. To build a national-level graphite deep processing and high-end application industrialization demonstration base, to promote the construction and development of high-end graphite industry in our province, and to serve the economic progress of Longjiang region.

Professor Huang Yudong said: "Graphite-based composite functional coating is one of the important directions for the high-end application of graphite. We specialize in the use of aerospace materials, through graphite composite silicone resin, graphite composite epoxy resin, graphite composite silicone resin A series of graphite-based functional coatings have been developed for the method of hetero-modified silicates. The graphite-based functional coatings have been developed in the fields of solid rocket motors, lunar core coring bags, missile noses, and missile thermal protection panels. Widely used, it meets the needs of the national multi-model missiles and launch vehicles for such coatings, and provides a strong guarantee for the lunar exploration project and the national series of major projects."

The reporter learned that the graphite center technology is currently incubating four high-tech enterprises such as lithium ion battery anode materials and graphite flame retardant materials. It is expected that the output value will reach 50 million yuan within three years, which will effectively promote the development of high-end graphite industry in our province.

Talking about the future development goals of Graphite Center, Professor Huang Yudong said: "For the strategic needs and technical bottlenecks of high-end graphite applications, we will integrate superior resources, carry out deep-level institutional reforms, and form a source of technological innovation that supports the high-end application of graphite in Heilongjiang Province. Power base. Solve the key bottleneck problem of high-end graphite application. It is formed in four aspects: graphene preparation, structural control and functional devices, advanced graphite-based new energy materials, graphite composite materials and graphite raw materials refinement processing, advanced testing and analysis technology. A number of major innovations supporting the high-end application technology of graphite in Heilongjiang Province.
