When used as electrode material, graphene can effectively reduce the size of the active material, prevent agglomeration of nanoparticles, improve electrons and ions transmission capacity, as well as enhancing the electrode's mechanical stability. As a result, graphene-containing electrode materials have high capacity and good rate performance.
Improved electrodes also allow for the storage of more lithium ions and increase the battery's capacity. As a result, the life of batteries containing graphene can last significantly longer than conventional batteries (Bolotin et al. 2008).
Existing studies show that pure graphene can't become a direct substitute for current carbon-based commercial electrode materials in lithium ion batteries due to its low coulombic efficiency, high charge–discharge platform and poor cycle stability (Atabaki & Kovacevic 2013).
