Once again, graphene has proven itself to be a rather special material:

...

For researchers it is. As far as commercial applications go, it’s a dud.

[Husker24]

Mixed with plastic it’s incredibly strong, bullet proof.

But I want a million watt graphene tube guitar amp!

As far as commercial applications go, it’s a dud.

Not really, graphene based products are already hitting the market:

"Turnigy Graphene packs utilize carbon in the battery structure to form a single layer of graphene just 0.335nm thick, making that type of battery substrate the thinnest known to mankind. The graphene particles form a highly dense compound allowing electrons to flow with less resistance compared to traditional Lipoly battery technologies. The result is a battery capable of maintaining greater power output whilst remaining much cooler under load. Since heat and resistance are the natural enemy of batteries Graphene chemistry has significantly reduced these problems and the result is an incredible boost in cycle life. Turnigy Graphene batteries are the new standard for serious hobbyists who require POWER ON DEMAND."
