Lithium-ion battery materials and application analysis

Lithium-ion battery materials Lithium-ion battery anode materials are roughly divided into the following categories: The first is carbon anode materials: the anode materials that have been actually used in lithium-ion batteries are basically carbon materials, such as artificial graphite, natural graphite, Mesophase carbon microspheres, petroleum coke, carbon fiber, pyrolytic resin carbon, etc. The second 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 third type is a lithium ion-containing transition metal nitride anode material, and there are currently no commercial products. The fourth type 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. There are currently no commercial products. The fifth type is nano-scale anode materials: carbon nanotubes, nano-alloy materials. The sixth nano material is nano oxide material: At present, Hefei Xiangzheng Chemical Technology Co., Ltd. is based on the latest trends in the market development of the lithium-ion battery new energy industry in 2009. Many companies have begun to use nano titanium oxide and nano silicon oxide to add to the traditional The graphite, tin oxide, and carbon nanotubes inside, greatly improve the charge and discharge capacity and the number of charge and discharge of lithium-ion batteries. The application of lithium-ion batteries With the development of microelectronics technology in the 20th century, more and more miniaturized devices have placed high demands on power supplies. Lithium-ion batteries have subsequently entered a large-scale practical stage. The earliest application was the lithium-ion subprimary battery, which was used in cardiac pacemakers. Since the self-discharge rate of the lithium-ion sub-battery is extremely low, the discharge voltage is very gentle. It is possible to implant the pacemaker into the human body for long-term use. Lithium-ion manganese batteries generally have a nominal voltage higher than 3.0 volts, which are more suitable for integrated circuit power supplies and are widely used in computers, calculators, and watches. Nowadays, lithium-ion batteries are widely used in mobile phones, notebook computers, power tools, electric vehicles, standby power supplies for street lights, navigation lights, and small household appliances. It can be said to be the largest application group. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
