Clarification of important types of negative materials for lithium-ion batteries

Types of anode materials for lithium-ion batteries ●Carbon anode materials The anode materials actually used in lithium-ion batteries are basically carbon-based materials, such as artificial graphite, natural graphite, mesophase carbon microspheres, petroleum coke, carbon fiber, and pyrolytic resin Carbon etc. Among the carbon materials, carbon nanotubes and graphene are mainly used. For years, graphene material has been one of the most popular research materials by scientists. ●Tin-based anode material Tin-based anode material can be divided into two types: tin oxide and tin-based composite oxide. Oxides refer to the oxides of tin in various valence states. ●Silicon-based anode materials In order to improve the invariance of silicon-based anode materials, all silicon materials are nanosized, and important research biases include: silicon nanoparticles, silicon nanowires, silicon thin films, and 3D multi-space silicon. ●Lithium titanate negative electrode material This material not only has a very high safety performance, and does not form an SEI film, so it will not reduce the battery capacity due to formation and has a good cycle performance. ●Nano tungsten oxide purple tungsten oxide has very high chemical activity, which can enhance electronic conductivity. Due to the low internal resistance of the material and excellent Li ion diffusivity, the recovery of purple tungsten oxide as the negative electrode of the battery can achieve high current charge and discharge. At present, many lithium battery companies have begun to use nano-tungsten oxide to add to the traditional graphite, tin oxide, and carbon nanotubes to greatly increase the charge and discharge capacity and the number of charge and discharge of lithium ion batteries.
