What are the advantages of graphene in the application of lithium battery electrode materials?

The application advantages of graphene in lithium battery electrode materials. Lithium batteries need to be better developed. They want to break through and innovate in the future and solve the problems they are facing. Therefore, the best way is to start from lithium battery materials. Graphene is the current lithium battery. The research on battery materials is more of a new type of material. There are not a few researches in recent years. Graphene has good electrical conductivity and specific properties. If it can be used as a lithium battery anode material, you can improve many problems and greatly improve the cathode. The capacitance and discharge performance of the material, so why not use it? There is no reason to miss it, is it? Graphene graphene material is different, the material and spring pure graphene cycle Coulomb efficiency is very low, high charge and discharge platform and poor cycle stability, The most important thing is that it cannot replace current commercial carbon materials, which means that it cannot be used directly as a cathode material for lithium batteries, but graphene can be used as a substrate and is a good material. Electrode materials play a greater role in lithium batteries. , Make graphene and pure natural graphite as well as carbon nanotubes and fullerenes consistent with carbon materials, through the special layered structure of graphene, change the properties of the material and the transmission of electrons. At the same time, the inter-layer spacing of the mixed graphene increases, providing more space for lithium storage. In addition, graphene can also be used to modify other non-carbon-based anode materials. However, the disadvantage is that the volume expansion and contraction change greatly during the lithium embedding/delithiation process. When used alone, graphene-doped composite materials can improve the shortcomings of the two materials. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
