The development of basic materials industry is related to the quality and development potential of manufacturing industry. The "Development Plan of Basic Materials Industry in Guizhou Province in the 14th Five-Year Plan" just issued a few days ago proposes to accelerate the development of high-end, agglomeration, chain, greening and integration of basic materials industry in our province. The development of basic materials in Guizhou will be directed towards more sufficient supply, higher quality and smaller gap.
As an important carrier of the technological development of material industry in Guizhou Province, Guizhou Material Industry Research Institute has formed a technological innovation chain from applied basic research, engineering technology development, pilot test, industrial demonstration to large-scale production, which is an important technological innovation platform for the research and development and integration of key technologies of composite modified polymer materials in our province and even the whole country, and constantly promotes the basic materials from "laboratory" to "application field".
Deploy innovation chain around the industrial chain
Recently, Qin Shuhao, president of the Provincial Materials Industry Research Institute, and the team are stepping up the research on solid-state lithium battery technology-completing the integration and engineering of solid-state lithium battery technology.
Three years ago, the institute set up a research and development team for solid-state lithium batteries. "Among many solid-state battery systems, only sulfide solid-state batteries can surpass liquid lithium-ion batteries in comprehensive performance. How to improve the stability of sulfide electrolyte materials by simple process preparation, inhibit the irreversible reaction between electrolyte materials and positive and negative active substances, balance the compatibility between sulfide electrolyte materials and positive and negative electrodes and the high cost of sulfide electrolyte are the key links that restrict the industrialization process of sulfide solid-state batteries as power batteries. "
R&D personnel of the Provincial Institute of Materials are conducting experiments.
Qin Shuhao told reporters that in recent years, the research team of the Institute has focused on the development of low-cost sulfide electrolyte material batch preparation process, ultra-thin electrolyte continuous film-making process, battery system screening, and batch preparation process of 50Ah power battery. It is expected that the industrial production of solid-state lithium batteries can be realized in 2023.
According to the statistics of China Automotive Power Battery Industry Innovation Alliance, the installed capacity of power lithium batteries in China will reach a new high in 2020, reaching 63.6GWh. China’s lithium-ion batteries have a good development momentum. If solid-state lithium-ion batteries replace traditional lithium-ion batteries, there will be huge market space in the future.
"To deploy innovation chain around the industrial chain, it is a prerequisite to lock in the market demand in the selection of scientific research projects. Frequent contact with the market has kept everyone in the institute sensitive to the market prospects of scientific research results. " Qin Shuhao said frankly that since the establishment of the Provincial Materials Industry Research Institute for more than 10 years, it has performed well in the research and development of new functional materials, microporous foamed polymer materials, high-performance composite materials, functional polymer membrane materials, biodegradable polymer materials and environmental functional materials, and the scientific and technological achievements formed have been widely used in the fields of automobiles, household appliances, food packaging, building materials and so on.
Focus on the Frontier of Green Technology Innovation
Focusing on the frontier of green technology innovation is an important technical demand in the development of basic materials industry in our province. The "eat dry and squeeze out" of agricultural waste is the successful practice of the provincial material industry research institute to explore the green circular economy model. Using agricultural wastes such as straw and rice husk as raw materials, a bio-fertilizer containing biochar, humus and beneficial microorganisms was developed, and then spun into ingots, molded by poly-plastic, and manufactured into finished products.

"These fertilizers contain certain mineral nutrients, which can improve soil water and fertilizer conservation performance and improve soil nutrient status. Taking pepper as an example, it can increase its yield by more than 15%". In the lobby on the first floor of the Provincial Materials Industry Research Institute, Wu Xiao, the head of the Research Institute’s Achievement Transformation and Technical Service Center, showed reporters the biochar series products that have achieved 100 mu demonstration in many places in the province.
Reduction, harmlessness and resource utilization. The research institute proposed that agricultural wastes should be returned to the fields to improve the soil through the technology of "biochar+organic fertilizer compounding", and the demonstration research on the integration and application of biochar surface properties, pore structure regulation, metal oxide loading, microbial loading and organic fertilizer compounding technology was carried out, so as to develop carbon-based organic fertilizer and other environmental functional materials suitable for different crops. "It has the effects of improving soil organic matter content, reducing the amount of chemical fertilizer, promoting the growth of plant roots, improving crop quality and reducing the occurrence of crop diseases and insect pests. By converting straw into biomass charcoal, carbon dioxide in the atmosphere can be captured and converted into carbon and fixed in the soil, effectively increasing the soil carbon pool and offsetting the carbon emissions caused by economic development. " Wu Xiao said.
Located in Wawu Village, Bijiang District, tongren city, the application demonstration site of biomass carbon materials.
Under the background of "peak carbon dioxide emissions, Carbon Neutralization", with the continuous improvement of technical level and the deepening of environmental protection concept, the preparation technology of high-performance biodegradable polymer materials and environmental functional materials possessed by Provincial Institute of Materials Industry is welcoming new development opportunities. Wu Xiao said that the development layout of the research institute focuses on the development opportunities of biomaterials under the background of "double carbon". In order to accelerate the application of related products in the terminal field, the Provincial Materials Research Institute is working closely with Guizhou Guifu Fungus Industry Development Co., Ltd., Guizhou Delicious Fresh Dictyophora Industry Co., Ltd., Guizhou China Tobacco Industry Co., Ltd. and Guizhou Vegetable Group Packaging Materials Co., Ltd. to develop biodegradable plastic films, modified atmosphere films, reusable shopping bags and other packaging products.
Deep integration of Industry-University-Research
"Cooperate with Geely Automobile in the development and industrialization of injection molding application technology for micro-foamed automobile interior parts, provide them with lightweight solutions, and realize the development technology of series automobile interior parts. At the same time, through the selection of raw materials, special VOC adsorbents, special production equipment and process treatment, the residue of harmful gases in the base material is reduced. " Qin Shuhao told reporters that the Provincial Institute of Materials Industry has accelerated the construction of an innovative system with deep integration in Industry-University-Research, and provided full-chain, open-ended sharing services focusing on R&D and design for materials-related enterprises and innovative entrepreneurial teams.

In recent years, the Provincial Institute of Materials has successively established provincial-level dual-innovation demonstration bases, provincial-level creative spaces, municipal-level technology transfer centers and demonstration bases for the transfer and transformation of scientific and technological achievements, Anshun National High-tech Zone Research Center of National Composite Modified Polymer Materials Engineering Technology Research Center, and Guizhou Functional Polymer Materials Innovation Center (hereinafter referred to as the Innovation Center) to unite universities, research institutes and enterprises closest to the market with scientific and technological innovation resources, focus on the needs of industrial development, tackle key technical problems common to the industry, and push industrial development towards high quality.
In the way of "company+alliance", Guizhou Functional Polymer Materials Innovation Center has established product linkage mechanism and collaborative innovation mechanism, and formed a product research and development and production system oriented to high-end market demand.
Through the close cooperation and joint research of upstream and downstream enterprises in the industrial chain, and making full use of the advantages of technology, achievements, talents and equipment in the field of new materials, the resources of production enterprises in product pilot, industrial application, technology promotion and capital have opened up the division and barriers of innovative elements such as technology, achievements, talents, capital, equipment and application.
Industry-University-Research’s platforms are constantly emerging, and innovative achievements emerge one after another. At present, the Provincial Materials Research Institute has reached more than 200 cooperation projects with experts and teams in and outside the province, and cooperated with more than 200 enterprises in and outside the province, such as SAIC-GM-Wuling Automobile Co., Ltd. and Shanghai Volkswagen Co., Ltd., to realize the transformation and promotion of scientific research results.
"The research institute will focus on improving the industrial innovation ability, vigorously promote the integration of science and technology and economy, and build a four-in-one full-chain platform of’ technology development-achievement transformation-enterprise incubation-industrial cultivation’ to realize the organic combination of technology research and development, achievement transformation and industrialization."
