Among the negative electrode materials for lithium-ion batteries, graphite based carbon negative electrode materials have always been the main type of negative electrode materials due to their wide sources and low prices. In addition to the small market share of graphitized mesophase carbon microspheres (MCMB) and low-end artificial graphite, modified natural graphite is gaining increasing market share. China has abundant natural graphite mineral resources. In the industrialization of lithium-ion negative electrode materials using natural graphite as raw material, Shenzhen Beiterui Battery Materials Co., Ltd. promotes the development of traditional industries with high-tech, and uses unique shaping and grading, mechanical modification, and thermochemical purification technologies to process ordinary flake graphite into spherical graphite, increasing the purity to over 99.95%, with a maximum of 99.9995%. And through advanced surface modification technologies such as mechanical fusion and chemical modification, we have developed and produced high-end negative electrode material products with international leading levels. The first discharge capacity is above 360mAh/g, the first efficiency is greater than 95%, the compaction ratio is 1.7g/cm3, and the cycle life is 500 times. The capacity is maintained at over 88%.

　　The products are exported to countries such as Japan, South Korea, the United States, Canada, Denmark, India, and are used by more than 40 lithium battery manufacturers in China. The company produces 1800 tons of natural composite graphite (MSG, AMG, 616, 717, 818, etc.), 1200 tons of artificial graphite negative electrode materials (SAG series, NAG series, 316 series, 317 series), 3000 tons of spherical graphite (SG), 5000 tons of natural ultrafine graphite, and 600 tons of lithium manganese oxide positive electrode materials per year, and is continuously expanding its production scale. At the same time, it can meet customer needs, processes Develop products for customers based on equipment and existing issues. The quality of the products produced is stable and uniform, with excellent electrochemical performance and excellent processing performance. The specific surface area, compaction density, impurity content, and particle size distribution of the adjustable products can be adjusted. The main production equipment and testing instruments are imported from abroad, forming a part of the company's unique core competitiveness. Betray has led the development direction of the lithium-ion battery negative electrode material industry.
