When it comes to lithium-ion batteries, you can have fast charging speeds or high capacities -- take your pick. Now, Samsung researchers, working with Seoul National University, have figured out how to give batteries both qualities thanks to our old friend, graphene. By coating the electrodes with a thin, popcorn-shaped layer known as a "graphene ball," they were able to produce a battery that could fully charge in just 12 minutes with up to 45 percent more capacity. The research, if it pans out, could lead to lighter and faster-charging electric vehicles.
