The synergy between battery materials such as nanostructured nickel oxides,
Battery performances are related to the intrinsic properties of the electrode materials, especially for cathode materials, which currently limit the energy density [26, 27]. Graphene-based materials have become a hot topic since they substantially enhance the electrochemical performance of cathodes in LIBs and lithium sulfur (Li–S) batteries [ 28, 29 ].
