[Two departments: Strengthen the research and development and industrialization of high-safety lithium batteries, high-specific energy solid-state batteries, and low-cost long-life sodium batteries] On September 15, the Ministry of Industry and Information Technology and the National Development and Reform Commission issued the "15th Five-Year Plan for the Development of Electronic Information Manufacturing Industry." It mentioned that key materials such as high-voltage, high-stable and large-capacity cathode materials, high-capacity and low-expansion silicon-carbon anode materials, highly stable and high-ion conductivity solid electrolytes, and composite current collectors should be developed, and the research and development and industrialization of high-safety lithium batteries, high-specific energy solid-state batteries, and low-cost long-life sodium batteries should be strengthened.
