　　Technology type of anode material for lithium ion battery:

　　Anode materials are mainly divided into the following three categories: carbon materials (graphite), metal oxide materials and alloy materials. A good negative electrode material should meet the following requirements: high specific energy, low electrode potential relative to lithium electrodes; good reversibility of charge and discharge reactions; good compatibility with electrolytes and binders; small specific surface area (<10m2/g); High tap density (>2.0g/cm3); good size and mechanical stability during lithium insertion; abundant resources and low price; stable in the air, no toxic side effects, etc.

　　The current negative electrode materials mainly used are natural graphite and artificial graphite, among which natural graphite is mainly used in the 3C field, and artificial graphite is mainly used in the power field. The upper limit of the energy density of traditional graphite materials is 372mAh/g, which has a considerable margin compared with the energy density of current cathode materials. Subject to the requirements of future energy density and high-rate discharge of power batteries, despite the high price or the immature technology, high-end anode materials such as mesophase carbon microspheres (MCMB), lithium titanate, and silicon-based load materials have gradually entered the market with higher performance requirements. Comprehensive and higher battery anode material application.
