article_snippet: In the shorter term, it could lead to thinner, lighter, tougher and more efficient smartphones, laptops and wearables such as smartwatches, which could be charged much faster than they can now.
article_snippet: Graphene is the most conductive material in the world, but because Graphene is thin and flat Graphene doesn’t have the surface area needed to be used in batteries.
article_snippet: To increase the size and shape of this so-called super-material, scientists in South Korea have used graphene's sheet-like structure to create ‘pom-poms’.
article_snippet: To increase the surface area of graphene, in order to make it transfer more charge and make it more suitable for use in batteries, scientists at the Yonsei University in Seoul created graphene
article_snippet: Deep-fried pom-poms of graphene could ultimately make batteries in phones and tablets smaller, efficient, and more capable of storing and transferring charge.
article_snippet: This created so-called nanochannels, which increased the area in which charge could be transferred.
article_snippet: Early tests with the graphene pom-poms showed that they performed better as electrodes compared to typical sheets of graphene.
