Graphene battery ?

Is Samsung is ready to ditch lithium-ion smartphone batteries in favor of graphene cells?

according to a new rumor wave that emerged on Chinese social media network Weibo, maybe, after more r&d, proto-types and testing

"... smartphones of the future, the batteries will consist of several connected blocks, charged in parallel. Such technology is already equipped with Oppo, Vivo, OnePlus and Apple, but after 3-5 years the list will expand. The use of multi-cellular batteries will increase the speed of fast charging. It means that it takes only 6 minutes to charge from 0 to 100% of a smartphone with such a battery at 9 Wt."

Nicely documented! And yeah, graphene has been pegged as an energy-storage solution for a few years now, with development mostly for large-cell energy needs, but definitely doable on a phone.
