Performance characteristics of lithium battery anode and cathode materials

Lithium battery cathode material. The battery cathode material of lithium battery is one of the important raw materials for determining battery performance, and it is also a key source of the commercialized lithium battery at this stage. Its characteristics and price are very harmful to rechargeable batteries. At this stage, the key battery cathode materials used for lithium batteries are lithium manganese oxide batteries, lithium cobalt oxide batteries, lithium iron phosphate batteries, and ternary materials. The key battery cathode materials include carbon materials and silicon-based raw materials. The key performance parameters of the positive electrode material of the rechargeable battery include: composition, molecular structure, particle size distribution, tap density, specific surface, PH value, initial charge-discharge specific volume, high efficiency of initial battery charging, and cycle system service life. The characteristics of lithium batteries lie in the structure and characteristics of the internal raw materials of rechargeable batteries, and the characteristics of battery cathode materials more immediately determine the characteristics of rechargeable batteries. Therefore, the battery cathode materials of lithium batteries must consider the basic characteristics of lithium batteries. Lithium battery cathode materials have unparalleled advantages in the development, design and industrial development of lithium battery batteries. They have a sound whole industry chain and excellent trends in the view of sustainable development: Ni and Mn are rich in natural resources, and rare metal smelters are technologically perfect. The positive-level and positive-level precursor industry chain has a complete range, and the industry application and operation of rechargeable batteries and battery cathode materials are large, and they are actively deploying recycling and reuse. In recent years, the category of lithium batteries has shown a steady and continuing upward trend, and battery cathode materials have entered an unprecedented opportunity. There are various new materials, and my country and national standards are required to continue to be announced. The negative electrode material of lithium battery. Among the raw materials of lithium battery, the negative electrode material of the battery is the most important component, which has a greater impact on the overall characteristics of the rechargeable battery. The characteristics of the negative electrode material of the lithium battery also immediately affect the characteristics of the rechargeable battery, and the cost is about 5 to 15% of that of the lithium battery. Nowadays, battery anode materials are mainly divided into two categories. One is carbon raw materials used for commercial activities, such as pure natural high-purity graphite, soft carbon, etc., and the other is non-carbon materials that have been scientifically developed and designed but have broad industry prospects. Battery cathode materials, such as silicon-based raw materials, alloy products, tin-gold raw materials, etc. Recently, the sales market of lithium battery cathode materials has been operating stably, and the sales volume has clearly improved with the slow increase in the production and sales rate of the middle and lower reaches. The company’s product quotations are relatively stable. At this stage, the price of battery cathode materials in my country is dominated by the low-end and middle-end products, with more than 10,000 yuan/ton for mid-range products, and 70-100,000 yuan/ton for high-end products. Based on the sales volume data information of power lithium batteries in 2019-this year, and based on the calculation basis of 1kwh lithium battery consumption about battery anode materials, it is predicted that the sales volume of power lithium batteries in my country in 2019-this year will reach 230,000 tons and 30% respectively. Ten thousand tons. Once again, everyone's recognition of the decline in the price of lithium battery anode materials in the future is assumed. Assuming that the average price of battery anode materials drops by 5% every year, it is estimated that the annual output value of lithium battery anode materials in my country in 2019-this year will be 9.6 billion yuan each. And 12.1 billion yuan, the market capacity will increase by 10 billion yuan. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
