Graphite negative electrode for lithium batteries

source:Industry News release time:2024-01-10 Hits: Popular:AG11 battery

　　Graphite, also known as graphite in English, is a non-metallic mineral with a soft and slippery texture. It has unique physical and chemical properties such as high temperature resistance, oxidation resistance, corrosion resistance, thermal shock resistance, high strength, good toughness, high self-lubricating strength, strong thermal conductivity, and conductivity.

　　Graphite has many excellent properties and is widely used in industries such as metallurgy, machinery, electrical, chemical, textile, and national defense, such as graphite molds, graphite electrodes, graphite refractory materials, graphite lubrication materials, graphite sealing materials, etc. China is the country with the richest graphite reserves in the world, as well as the largest producer and exporter, occupying an important position in the world graphite industry.

　　The ideal graphite has a layered structure, with the layer formed by the carbon atoms of SP2 forming a huge plane similar to a benzene ring, and the carbon atoms between the layer planes are δ The bonds are interconnected, with a bond length of 0.142nm and a bond angle of 120 °. There is also a large π bond connecting all carbon atoms between the layers. The interlayer is 0.3354nm. Two crystal forms: hexagonal crystal system -2H type (a) and rhombic crystal system -3R (b) Ø can be converted to each other: grinding and heating.
