I. china baoan (000009):
1.20 17 to 2020, the total assets turnover rate is 0.29%, 0.4 1%, 0.4% and 0.34% respectively.
2. The subsidiary Betray is the world's largest supplier of cathode materials for lithium batteries, and has formed a complete industrial chain layout of cathode materials for lithium batteries, forming a closed loop from natural graphite ore, graphite processed products to finished cathode materials in the field of cathode materials; At present, the production capacity of cathode materials reaches 40,000 tons/year, and the production capacity of lithium ferrous phosphate is10.7 million tons/year.
According to the intraday news on September 8th, china baoan recently reported to 23 yuan, with a turnover of 462,500 lots, with a total market value of 59 1.4 1 100 million yuan.
Second, Xiang Fenghua (300890):
1.20 17 to 2020, the total assets turnover rate is 0.62%, 0.6 1%, 0.56% and 0.3 1% respectively.
2. By building a standardized production workshop, introducing advanced machinery and equipment and high-quality and experienced production-related personnel, we will build a workshop with high automation level, reasonable spatial structure and layout, clean and environmental protection, and form an annual production capacity of 20,000 tons of high-end artificial graphite anode materials and 654.38+100,000 tons of high-end natural graphite anode materials to meet the needs of the company's business development in the next few years. On September 8, Xiang Fenghua's share price rose by 6.87% in three days, and the latest price was 56.32 yuan, up by 0.29%, with a turnover of 40.9205 million yuan.
1, natural graphite anode material is made of natural flaky crystalline graphite, and its high crystallinity is naturally formed after crushing, spheroidizing, classification, purification, surface treatment and other processes. Because of the high surface active point of natural flake graphite, it can not be directly used as negative electrode material, so it needs to be surface modified. The artificial graphite anode material is made of petroleum coke, needle coke and pitch coke by calcining at a certain temperature, then crushing, grading and graphitizing at high temperature. Its high crystallinity is formed by high temperature graphitization.
2. Graphite is an ideal anode material, which has occupied a dominant position since the birth of lithium-ion batteries, and has incomparable advantages such as relatively low cost, abundant reserves, high energy density, high power density and long cycle life. Recent research shows that the lithium storage performance of graphite can be further improved, which shows its good application prospect in advanced lithium-ion batteries for electric vehicles and large energy storage power stations.
3. However, in order to obtain graphite anode with higher performance, it is necessary to deeply understand the basic crystal structure and electronic structure of graphite and lithium-graphite intercalation compound (GIC), so as to adjust the microstructure through fine design and promote the kinetics of lithium ion embedding, storage and diffusion in graphite.
