What is the negative electrode material of lithium battery What are the negative materials of lithium battery?

Lithium battery anode materials: Lithium battery anode materials have a major impact on the first-time efficiency and cycle performance of lithium batteries. According to the ratio of the cost of lithium batteries, the negative electrode material accounts for 25% to 28% of the total cost of lithium batteries. With the advancement of technology, the current lithium battery anode materials have developed from a single artificial graphite to natural graphite, mesophase carbon microspheres, artificial graphite, soft carbon/hard carbon, amorphous carbon, lithium titanate, silicon carbon The coexistence of various anode materials such as alloys. How many kinds of anode materials are there for lithium batteries? The first is the anode material of carbon nano-level materials: the anode materials that have been actually used in lithium batteries are basically carbon materials, such as artificial graphite, natural graphite, mesophase carbon microspheres, petroleum coke, carbon fiber, and pyrolytic resin Carbon etc. The second type is alloy-based anode materials: including tin-based alloys, silicon-based alloys, germanium-based alloys, aluminum-based alloys, antimony-based alloys, magnesium-based alloys and other alloys. There are currently no commercial products. The third type is tin-based anode materials: tin-based anode materials can be divided into tin oxides and tin-based composite oxides. Oxide refers to the oxide of tin metal in various valence states. There are currently no commercial products. The fourth type is lithium-containing transition metal nitride anode materials, and there are currently no commercial products. The fifth type is nano-scale materials: carbon nanotubes, nano-alloy materials. The sixth nano-anode material: nano-oxide material.
