Types and characteristics of battery materials

Lithium -ion battery materials are currently widely used battery materials. Using it can greatly improve the performance of the battery and extend the service life of the battery. Mainly positive materials, negative materials and electrolytes. Among them, the positive pole materials mainly include lithium cobaltate, lithium iron phosphate, and ternary materials, and the main materials of the negative electrode are graphite and silicon. Sodium ion battery materials are similar to lithium -ion battery materials, but because the ion radius of sodium ions is larger than lithium ion, sodium ion material can use cheap sodium resources instead of expensive lithium resources. At present, research is mainly concentrated in the positive pole materials. The use of sodium ion materials can be widely used in new energy fields such as solar energy and wind energy.Metal air battery material is a new type of battery material, mainly including zinc air batteries, aluminum air batteries, etc. Because m

The main methods of graphite purification

1 Flotation methodFlotation method is a commonly used method for purifying minerals. Due to the difficulty of water infiltration on the surface of graphite, it has good floatability and is easy to separate from impurity minerals. In China, flotation method is generally used for beneficiation of graphite.The flotation of graphite raw ore generally uses the positive flotation method first, followed by reverse flotation of the positive flotation concentrate. High grade graphite concentrate can be obtained by using flotation method. The grade of flotation graphite concentrate can usually reach 80% to 90%, and the purity can reach around 98% by using multi-stage grinding.The commonly used collectors for flotation of crystalline graphite are kerosene, diesel, heavy oil, sulfonic acid esters, sulfate esters, phenols, and carboxylic acid esters. The commonly used foaming agents are 2 # oil, 4 # oil, terpineol oil, ether alcohol, and butyl ether oil. The adjusting agents are lime and sodium ca

Graphite products manufacturers introduce the use of graphite block on cement back kiln in detail

The concrete flip kiln is the insulation machinery and equipment that conducts actual operation under negative pressure. The sealing situation on both sides is immediately associated to the production of cement clinkers, quality and energy consumption. In the work of improving and improving kiln heads and kiln tails, it is one of the effective ways to flip the high -yield and energy -saving of the kiln chemical plant. However, because the working conditions on both sides of the flip kiln are extremely high, not only the temperature is high, but also has flipping and shaking together. Therefore, the sealing work of the flip kiln chemical plant is both the key and difficult. Graphite block has the inevitable heat resistance characteristics and excellent authenticity characteristics, which can achieve a good regulation of flip kiln sealing. Therefore, in China, the graphite block has been used as a sealed material in the early 1950s. At this stage, the current stage. The use of use is st

Let's talk about the basic characteristics of graphite

I. Special seismic resistance: Graphite's expansion gear is different, so the macro expansion coefficient is not large. In the case of sudden changes in temperature, graphite volume has not changed much; coupled with its good thermal conductivity, graphite resistance is excellent.Second, lubrication: The graphite layer is Van Der Waal Forces, which combines weak combination to make it lubricating. The lubrication of graphite depends on the size of the graphite scales. The larger the scales, the smaller the friction coefficient, the better the lubricity.Third, good chemical stability and resistance to erosion: Graphite has good chemical stability at room temperature, not subject to any strong acid, strong alkali and organic solvents; the carbon atom in the graphite layer is firm Combining, the surface of graphite phosphorus can be very low, not moisturizing by melting furnaces, and strong resistance to erosion. However, graphite is prone to oxidation in the air, and anti -oxidation mea
