wherein at least some of the metal additive is positioned between adjacent pairs of the graphene strips.

2. The graphene strap of claim 1 , wherein:
the graphene strips include a first graphene strip and a second graphene strip; and
the metal additive is applied to a surface of the first graphene strip.

3. The graphene strap of claim 1 , wherein:
the metal additive comprises electroplated metal, and
the electroplated metal comprises at least one of: copper and silver.

4. The graphene strap of claim 1 , wherein the binding material comprises a solder paste reflow.

5. The graphene strap of claim 1 , wherein each graphene strip is structured with graphene nanoplatelets pressed together.

6. A graphene strap comprising:
a plurality of graphene strips comprising strips of graphene nanoplatelets;
a metal additive applied to each of the plurality of graphene strips; and
a binding material configured to couple the plurality of graphene strips together;
wherein:
the graphene strips include a first graphene strip and a second graphene strip;
the metal additive is applied to a surface of the first graphene strip; and
the binding material is applied on the surface of the first graphene strip in locations where the metal additive is not applied.

7. The graphene strap of claim 6 , wherein the binding material couples the first graphene strip and the second graphene strip around the metal additive.
