Sorry Heraclitus that info I don't have...and I don't think it would be honest to simply google it.
We do know that graphite is sold and has been for years. Graphene is a somewhat newer product and is in development/testing stages as yet. I think it will go the same way as lithium,but that is my opinion. It is certainly making news and research and development show is as an amazing product. However...end users will need to develop applications for it and again...that will come.
Sri Lankan graphite is very high grade and limited, hence my reason to be long on this stock.
