Lithium ion battery negative electrode material: (1) carbon material: graphit carbon material, amorphous carbon material. Such as graphite, soft carbon, intermediate phase carbon microspheres have been developed and studied, hard carbon, carbon nanotubes, and Pakistani ball C60, etc. are being studied. (2) Other materials: nitride, silicon-based materials, tin-based materials, new alloys, nano oxides, and the like.
Negative electrode material: Multiple graphite. New studies have found that titanate may be better materials. Negative electrode reaction: lithium ion is disengaged at the time of discharge, and the lithium ion is inserted during charging. When charging: XLI + XE6C-LiXC6 is discharged: LiXC6 → XLI + XE + 6C is generally divided into the following:
The first is carbon negative electrode material: graphitized carbon material, amorphous carbon material. Such as graphite, soft carbon, intermediate phase carbon microspheres have been developed and studied, hard carbon, carbon nanotubes, and Pakistani ball C60, etc. are being studied. The negative electrode material actually used for lithium-ion batteries is basically carbon material, such as artificial ink, natural graphite, intermediate phase carbon microspheres, petroleum coke, carbon fiber, pyrolysis resin carbon, and the like. The second is a tin-based anode material: two oxides and tin-based composite oxides which can be divided into tin. Oxides refer to oxides of various valence metal tin. No commercial products.
