    New method of graphene functionalization

    Graphene has outstanding physical, optical and mechanical properties and has been used in transparent touch screens, aerospace and biomedical fields. However, graphene has relatively few uses in the electronic field. Mainly because, unlike semiconductors used in electronics, graphene lacks a band gap. In electronics, this band gap refers to the space where there is no energy level that can be occupied by electrons. It is essential for the interaction with light. of.

    What are the advantages and disadvantages of lithium batteries?

    Graphene has more advantages than traditional batteries. In terms of service life, its service life is twice that of lithium batteries and four times that of hydrogenated batteries. In terms of weight, its weight is only about half of traditional batteries. In terms of charging rate. Graphene batteries can be increased dozens of times or even hundreds of times.

    What are the advantages, disadvantages and disadvantages of graphene batteries

    Graphene battery: Graphene battery is a honeycomb flat film formed by sp2 hybridization of carbon atoms. It is a quasi-two-dimensional material with only one atomic layer thickness, so it is also called monoatomic layer graphite. A new energy battery has been developed by utilizing the characteristics of rapid and massive shuttle movement of lithium ions between the graphene surface and the electrodes.
