CR2032 button cell batteries

　　CR2032 button cell batteries cathode material.

　　The cathode material of lithium batteries is one of the important materials that determines battery performance. It is also an important source of currently commercialized lithium batteries. Its properties and price have a great impact on rechargeable batteries. Currently, the cathode materials used in lithium batteries mainly include lithium manganese oxide batteries, lithium cobalt oxide batteries, lithium iron phosphate batteries and ternary materials. The cathode materials mainly include carbon materials and silicon-based materials.

　　The key performance parameters of battery cathode materials include: composition, molecular structure, particle size distribution, tap density, specific surface area, pH value, initial charge and discharge specific volume, initial battery charging efficiency, cycle life, etc.

　　The characteristics of lithium batteries lie in the structure and properties of the internal materials of the battery, and the properties of the battery cathode material more directly determine the properties of the battery. Therefore, the cathode material of the lithium battery must meet the basic performance requirements of the lithium battery.

　　The development and industrial development of lithium battery cathode materials in China has unparalleled advantages. It has a sound industrial chain and a good concept of sustainable development: Ni and Mn are rich in natural resources, and rare metal smelting plants are technologically advanced. The industrial chain of positive-grade and positive-grade precursors is complete in variety, the industrial application of rechargeable batteries and battery cathode materials is large-scale, and the company is actively and proactively arranging recycling and reuse.

　　In recent years, the field of lithium batteries has shown a trend of steady and continuous growth. Battery cathode materials have ushered in unprecedented opportunities. A variety of new materials have emerged, requiring the continuous release of domestic and national standards.

　　Anode materials for lithium-ion batteries

　　Among the raw materials for lithium batteries, the battery negative electrode material is the most important component and has a greater impact on the overall characteristics of the rechargeable battery. The properties of lithium battery anode materials also directly affect the performance of rechargeable batteries, and their cost is about 5~15% of that of lithium batteries.

　　At present, battery anode materials are mainly divided into two categories. One is carbon raw materials used for commercial purposes, such as natural high-purity graphite, soft carbon, etc., and the other is non-carbon materials that have been researched and developed 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 for lithium battery cathode materials has been operating stably, and sales have improved significantly with the slow increase in production and sales rates in the mid and downstream. Enterprise product quotations are relatively stable. At present, the price of battery cathode materials in China is dominated by the mid-to-low end, mid-range products are dominated by more than 10,000 yuan/ton, and high-end products are dominated by 70,000-100,000 yuan/ton.

　　Based on the sales data of power lithium batteries from 2019 to this year, and based on the calculation that 1kwh lithium battery consumes about anode material, it is predicted that the sales volume of power lithium batteries in China from 2019 to this year will reach 230,000 tons and 30,000 tons respectively. 10,000 tons level.

　　Once again combining our judgment on the future price decline of lithium battery anode materials, assuming that the average price of battery anode materials falls by 5% per year, the annual output value of lithium battery anode materials in China is estimated to be 9.6 billion yuan each from 2019 to this year. and 12.1 billion yuan, the market capacity will increase by 10 billion yuan.
