Although there are batteries already existing with the capability to store a tremendous amount of power but charging them takes time, and they are heavy. Others that could charge quickly discharge just as fast. But graphene batteries is a game changer as it could be charged super fast, and it would hold the charge. Conversely, quick energy draw from it won't damage the battery as graphene is a superconductor.

This will really be a gamechanger...Looking forward to slimer phones with long-lasting batteries.
