EXPLAINED: Samsung's fast-charging graphene-enhanced batteries

A team of researchers at the Samsung Advanced Institute of technology (Sait) found a way to create 3D, “popcorn-like” balls out of 2D, one-atom-thick graphene. Using affordable silica, the South Korea team made tiny spheres with diameters of roughly 10µm (1,000 times smaller than a centimetre).
