What are the common anode materials for lithium batteries? In the lithium battery materials, the negative electrode material is an important component, which can have a greater impact on the performance of the overall lithium battery. At present, anode materials are mainly divided into two categories, one is carbon materials for commercial applications, such as natural graphite, soft carbon, etc., and the other is a non-carbon anode material that is in the state of research and development, but the future direction is very good. For example, silicon-based materials, alloy materials, tin-gold materials, and so on. The negative electrode of the lithium battery is made by mixing the negative active material carbon material or non-carbon material, the binder and the additives to form a paste glue that is uniformly applied on both sides of the copper foil, dried and rolled. The negative electrode material is the main body of the lithium battery to store lithium, allowing the insertion and extraction of lithium ions during the charging and discharging process. When a lithium battery is charged, the lithium atoms in the positive electrode are ionized into lithium ions and electrons, and the lithium ions move to the negative electrode to synthesize lithium atoms with the electrons. During discharge, lithium atoms are ionized from the surface of the negative electrode in the graphite crystal into lithium ions and electrons, and lithium atoms are synthesized at the positive electrode. ●Carbon anode material This type of material is a balanced anode material in terms of energy density, cycle capacity, or cost input. It is also an important material that promotes the birth of lithium batteries. Carbon materials can be divided into two major categories. Categories, namely graphitized carbon materials and hard carbon. Among them, the former mainly includes artificial graphite and natural graphite. ●Natural graphite Natural graphite also has many advantages. Its crystallinity is higher, there are more places where it can be inserted, and the price is lower, making it an ideal lithium battery material. However, it also has certain drawbacks, such as poor compatibility when reacting with electrolyte, and many defects on the surface during pulverization, which will greatly adversely affect its charging or discharging performance.
