What are the details of the negative material characteristics of lithium-ion batteries?

The negative electrode of the lithium ion battery is made by mixing the negative active material carbonaceous material or non-carbonaceous material, the binder and the additives to make a paste glue that is evenly smeared on both sides of the copper foil, dried and rolled. Whether the lithium-ion battery can be successfully manufactured, the key lies in whether the negative electrode material that can reversibly release/intercalate lithium ions can be prepared. What kind of negative electrode materials are there? ▼Carbon anode materials In practical applications, the carbon anode materials of lithium-ion batteries are basically these kinds of carbon materials: artificial graphite, natural graphite, petroleum coke and carbon fiber. ▼Tin-based anode material Tin-based anode material can be divided into two types under general environment, one is tin oxide, and the other is tin-based composite oxide. Tin oxide generally refers to the oxide of metallic tin in various valence states. ▼Lithium-containing transition metal nitride negative electrode material is still in the research stage, and currently there is no commercial lithium-ion battery product that uses it as a negative electrode material. ▼Alloy anode materials There are still many types of anode materials for lithium-ion battery alloys, including tin-based alloys, silicon-based alloys, aluminum-based alloys and other alloys, but also alloy-based anode materials. There is no limited production in large quantities, and further research and development are still in progress. ▼Nano-level anode material Nano-level anode material can add more tiny other materials to the previous traditional anode material, which can greatly increase the charge and discharge capacity and the number of charge and discharge of lithium-ion batteries.
