Graphene is hyped like crazy for multiple applications… Not just for batteries.
see here Graphene - All You Need to Know
problem is that no one knows how to manufacture in commercial scale yet… Lot of lab based try outs and proofs have happened.
This is an interesting company - https://generalgraphenecorp.com/ … Graphite India has picked up closed to 46% stake in this company first and then they also recently increased stake again. Dont remember the total stakes the company holds now.
PS: This is a totally new world , with lot of ifs and buts on technology. Chance of success is weak as well… However, looking at Graphene Corp’s progress in last 2 years - they have figured out a way to mass produce sheets … not sure who is their customer for trials…
Desclosure : Invested in recent fall of stock as it was available very cheap…
