Advantage:

　　At present, the transportation of electric vehicles as a replacement fuel has become a hot spot at home and abroad. The development of high -quality cathode materials with high safety, high -power performance, and high service life is the research hotspot and difficulty of electric vehicles with ionic power lithium batteries.

　　At present, the positive electrode of a lithium -ion battery mainly uses carbon -based materials, but it still has certain defects in terms of use:

　　1. When charging, it is easy to generate lithium branches, which shortens the battery, thereby reducing its safety;

　　2. It is easy to form a SEI film, which causes the first charge and discharge efficiency to be reduced, and it has a higher irreversible capacity;

　　3. That is, carbon materials have a platform voltage with low (similar to metal lithium), which can easily cause electrolyte dissolving, so there is a safety risk.

　　4. In the process of lithium ion embedding and release, the volume of lithium ions has changed a lot, and the circulation stability is not good.
