How is the development of graphene anode materials in lithium batteries

The development of graphene anode materials in lithium batteries 1. The current status of international graphene development. At present, countries engaged in graphene industry research in the world include the United Kingdom, the United States, the European Union, South Korea, and Japan. The development status of each country is different. United Kingdom: As the birthplace of graphene, the United Kingdom is a global leader in the basic research and development of graphene, but there are fewer graphene companies engaged in commercial development, so it is not its strong point in the use of graphene. United States: The United States has invested early in the research of graphene, the industrialization and use of graphene are relatively fast, its industrial layout is also diversified, and the industrial chain is relatively complete. European Union: The European Union's graphene research started early and has a strong systemic nature. It has promoted graphene research to a strategic level, with strong financial support and solid basic research. South Korea: The development of the Korean graphene industry is closely integrated with production, education and research, and the development of basic research and industrialization is relatively balanced, and the overall development speed is relatively fast. Japan: Relying on its good carbon material industry foundation, Japan is one of the first countries in the world to conduct graphene research. The integration of production, education and research is relatively close, and the overall development is relatively comprehensive. 2. The development status of domestic graphene. From the perspective of the number of patents, the number of domestic graphene patent applications in my country is concentrated in the Yangtze River Delta region. Jiangsu has the largest number of applications (4102), followed by Guangdong (2537) and Beijing (2333), and Northeast China The number of patent applications in the western region is relatively low. From the perspective of industrial agglomeration, most of the current domestic graphene companies are located in the eastern coastal area, especially the Yangtze River Delta, the Pearl River Delta, and the Beijing-Tianjin-Hebei-Shandong aggregation area. Graphene's lithium battery anode material should be clearly structured, doped and prepared and combined. The study of electromagnetic anode materials can enhance the efficiency of graphene use, reduce material input costs, and realize the commercial development of graphene use. Based on the behavior of the graphene anode material and the element composition in the in-situ characterization situation, the structural changes can be further decomposed, and the foundation for further research and manufacturing of graphene-based power lithium batteries with practical use value can be laid.
