Lithium-ion battery anode materials are roughly divided into six types: carbon anode materials, alloy anode materials, tin-based anode materials, lithium-containing transition metal nitride anode materials, nanoscale materials, and nanoscale anode materials.

The first is carbon anode material: the anode materials actually used in lithium-ion batteries are basically carbon materials, such as artificial graphite, natural graphite, mesocarbon microspheres, petroleum coke, carbon fiber, pyrolysis resin carbon, etc.

The second is tin-based negative electrode material: tin-based negative electrode material can be divided into two kinds of tin oxide and tin-based composite oxide. Oxides refer to oxides of metal tin in various valence states. There are no commercial products.

The third is a lithium-containing transition metal nitride anode material, and there is no commercial product.

The fourth is alloy anode materials: including tin-based alloys, silicon-based alloys, germanium-based alloys, aluminum-based alloys, antimony-based alloys, magnesium-based alloys and other alloys, and there are no commercial products.

The fifth is nanoscale anode materials: carbon nanotubes and nanoalloy materials.

The sixth nanomaterial is nanooxide material.
