Graphite as anode for lithium-ion battery
Lithium-ion batteries as a environment-friendly battery, Researchers keep focousing on its negative electrode material these years.. In recent years, people found some new high-capacity, high-performance anode materials,. It is roughly divided into non-carbon-based anode materials and carbon-based anode materials. The carbon-based anode materials include graphite and amorphous graphite materials.
The former includes mesophase graphite carbon microbeads (MCMB), natural graphite, artificial graphite, carbon fiber, and coke. The amorphous carbon materials occurrence is mainly due to its small form, which can stand about2 000 ℃ high temperature heat treatment. Compared to lithium (3 800 mAh / g),it is much smaller, so researchers concern of amorphous carbon. In actual production, the carbon and graphite is more important because of its high conductive performance and lower price. So Graphite is widely used in batteries as an electrode material primarily for its high electrical conductance and low reactivity these days..
Graphite is a relatively abundant global resource, but known deposits of economic scale are found in China. Amorphous graphite is abundant in Chenzhou City,South of China.
