Development of Lithium Battery Materials

　　The negative electrode materials of lithium batteries are generally divided into the following types:

　　The first type is carbon negative electrode material:

　　At present, most of the negative electrode materials used in lithium-ion batteries are carbon materials, such as artificial graphite, natural graphite, mesophase carbon microspheres, petroleum coke, carbon fiber, pyrolysis resin carbon, etc.

　　The second type is tin based negative electrode material:

　　Tin based negative electrode materials can be divided into two types: tin oxide and tin based composite oxide. Oxides refer to the oxides of various valence metal tin. There are currently no commercial products available.

　　The third type is lithium containing transition metal nitride negative electrode materials, and there are currently no commercial products available.

　　The fourth type is alloy negative electrode materials:

　　There are currently no commercial products available, including tin based alloys, silicon-based alloys, germanium based alloys, aluminum based alloys, antimony based alloys, magnesium based alloys, and other alloys.

　　The fifth type is nanoscale negative electrode materials: carbon nanotubes, nano alloy materials.

　　The sixth type of nanomaterial is nano oxide material: Currently, Hefei Xiangzheng Chemical Technology Co., Ltd. has started using nano titanium oxide and nano silicon oxide to add to traditional graphite, tin oxide, and nano carbon nanotubes based on the latest market development trends of the lithium battery new energy industry in 2009, greatly improving the charging and discharging capacity and frequency of lithium batteries.

　　Technological process is an important indicator to measure whether an enterprise is progressiveness, competitive in the market and able to keep ahead of competitors. With the rapid development of China's lithium battery material market, the application and research and development of related core production technologies will inevitably become the focus of attention for industry enterprises. Understanding the research and development trends, process equipment, technological applications, and trends of core technologies for lithium battery material production is crucial for enterprises to improve product technical specifications and enhance market competitiveness.
