Application of Graphene in Lithium-Ion Batteries

Abstract

Graphene has excellent conductivity, large specific surface area, high thermal conductivity, and sp2 hybridized carbon atomic plane. Because of these properties, graphene has shown great potential as a material for use in lithium-ion batteries (LIBs). One of its main advantages is its excellent electrical conductivity; graphene can be used as a conductive agent of electrode materials to improve the rate and cycle performance of batteries. It has a high surface area-to-volume ratio, which can increase the battery’s energy storage capacities as anode material, and it is highly flexible and can be used as a coating material on the electrodes of the battery to prevent the growth of lithium dendrites, which can cause short circuits and potentially lead to the battery catching fire or exploding. Furthermore, graphene oxide can be used as a binder material in the electrode to improve the mechanical stability and adhesion of the electrodes so as to increase the durability and lifespan of the battery. Overall, graphene has a lot of potential to improve the performance and safety of LIBs, making them a more reliable and efficient energy storage solution; the addition of graphene can greatly improve the performance of LIBs and enhance chemical stability, conductivity, capacity, and safety performance, and greatly enrich the application backgrounds of LIBs.
