Why hasn't graphene batteries become the dominant battery for electric vehicles?

In electric vehicles, the three-electric system is the center, during which the battery is the center of the center. As the power source and the power source of the whole vehicle, the battery plays a very important purpose. At present, the main-flow battery of electric vehicles is a lithium battery, which has a moderate energy density and relatively mature production cost advantages. Why didn't graphene batteries replace lithium batteries as electric vehicle batteries? Using graphene or lithium is nothing more than loading more electrons. Lithium ions can carry more electrons than graphene. The more electrons they carry, the more unstable they are. Even if the capacity of graphene is broken, the result is to add a risk factor. All-graphene batteries are very expensive and difficult to prepare, making mass production impossible. Graphene battery is a new energy battery developed by using the characteristics of rapid and extensive movement of lithium ions between the surface of graphene and electrodes. Some amazing data released today are basically from graphene batteries with extremely high purity. It is only in the concept stage or the real graphene battery in the laboratory that the electrode part is mainly used for graphene before it is called a graphene battery, while the current commercial graphene battery The battery is only used for conductive glue, that is, graphene is incorporated into the original electrode. Theoretically, the performance of the battery has been improved, but there is no qualitative jump. It is still far from the theory, and the cost is still high. The prospects for the use of graphene are very broad, but many technical problems have not yet been commercialized, so it is normal that there is no large-scale implementation. In conclusion, it is a question of whether graphene can be used to replace lithium batteries. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
