Silicon–graphene is used in high voltage LiPo batteries, while Graphene was theorized in the late 1800’s and modeled in the 1950’s it hasn’t been isolated until 2004 where the first single layer Graphene was created using a sticky tape of all things. So while in the 70’s people were thinking about Graphene application because the physics were modeled and studied we didn’t had the ability to produce it and we still have limited ability to produce it at scale. This isn’t just about hype but rather what is possible with our current level of technology and manufacturing capabilities.
