Like traditional batteries, a graphene battery contains the structure of having the two electrodes, cathode and anode. It has electrolytes that help to transfer the ions. In traditional batteries, manufacturers mostly use pure solid-state metal to form the cathode, however, graphene batteries still use solid metals but are mixed with graphene, creating a composite material.
The concentration of graphene in the cathode differs depending on where they will use the battery. The measure of graphene joined into the cathode, for the most part, relies on the exhibition necessities and depends on the current efficiencies and shortcomings of the strong state antecedent material.
