China’s new flexible graphite rod industry is under construction and development, graphitized coke “Eighth Five-Year Plan” period has achieved a number of flexible graphite processing technology and equipment, but is still in the pilot stage. Lithium-ion batteries in China are still in the pilot stage, but stable anode materials have been developed with natural graphite. Its capacity density is 350mAh/g. China has imported and digested and absorbed 5 kinds of color TV tube graphite milk. Blanking silicon graphite products is currently a blank in China. The present situation and development trend of graphite processing technology at home and abroad China is a big country with natural graphite resources, and its reserves, output and exports rank first in the world. However, due to insufficient input in technology development, the production and processing of flake graphite are still the main raw materials. Carbon-graphite material is a new and promising material, which is widely used in high-tech fields. Developed countries invest manpower and financial resources to develop and research. The deep processing technology of natural graphite has made rapid progress, and some new industries have been formed. At present, the flexible graphite industry in the United States, Japan, Germany and France occupies a leading position. Japan is leading technology in producing nuclear grade ultra low sulphur (S<500ppm) and high purity (S<50ppm) products. Among them, high purity flexible graphite can only be produced in Japan. The world’s largest output of flexible graphite is 1.5~2.0 million tons or more. As for anode materials of lithium-ion batteries, graphite anode plate has excellent capacitance. Modified graphite has been used as anode materials for lithium-ion batteries in the United States and Japan, and has become an industry. Silicon dipped graphite is currently produced in Germany, the United States and Russia. The product is a new material with high hardness, high mechanical strength, wear resistance, corrosion resistance and good lubrication in a wide temperature range. Compared with silicon carbide products, the biggest feature is high yield and low price. Due to the shortening of the replacement cycle of color TV sets, the performance requirements of graphite milk for color TV tubes are changing rapidly. Foreign countries still attach great importance to the research and development of color TV tube graphite milk.
