Is your Graphene Battery genuine?

Interesting claim in this weekend's paper.

Mine is. It says so in the advert, there’s a picture and everything! 😛

There is a bike frame that is advertised as made with graphene. Actually what they do is add a mix of powdered graphene into the epoxy. 

As I understand it the graphene fills the weave of the carbon cloth and adds loads of strength and reduces weight. 

Would be ideal mix for glider wings.

LOL. Graphene is a sheet which is only one layer of molecules thick. If it's powder, it's graphite.

I’m aware of carbon nanotubes (e.g Easton CNT) being used in bike parts.  Graphene would be in sheets or platelets: “UK-based Dassi Bikes offer what they refer to as "the world’s first bike made with graphene". The Dassi bike frame is said to contain 1% graphene throughout six layers underneath the carbon surface layer. The frame weighs just 750g and engineers predict that sub 400g frames could be achievable.”
