Carbon negative electrode material

　　The anode materials actually used in lithium ion batteries are basically carbon materials, such as artificial graphite, natural graphite, mesophase carbon microspheres, Petroleum coke, carbon fiber, pyrolysis resin carbon, etc.

　　Tin based negative electrode material

　　Tin based negative electrode materials can be divided into two types: tin oxide and tin based composite oxide. Oxides refer to the oxides of various valence metal tin. There are no commercial products.

　　nitride

　　There are no commercial products.

　　Alloy class

　　There are no commercial products, including tin based alloys, silicon based alloys, germanium based alloys, aluminum based alloys, antimony based alloys, magnesium based alloys, and other alloys.

　　Nanoscale

　　Carbon nanotube and nano alloy materials.

　　Nano oxide

　　According to the latest market development trends in the lithium battery new energy industry in 2009, many companies have started using nano titanium oxide and nano silicon oxide to add to traditional graphite, tin oxide, and carbon nanotubes, greatly improving the charging and discharging capacity and number of charging and discharging times of lithium batteries.
