    A graphene breakthrough hints at the future of battery power
    From laptops that charge in 15 minutes to electric scooters, the first round of graphene-based products could finally deliver on the promise of the much-hyped wonder material

    "Catch the 1E bus from central Belgrade, Serbia, and you’ll be riding the future.

    The five Chariot e-buses that operate on this route are some of the first in the world to run solely on supercapacitors, a fast-charging alternative to batteries that could revolutionize how we store energy.

    Instead of holding electricity as chemical potential, like a battery, supercapacitors (also known as ultracapacitors) store it in an electrical field, like static collecting on a balloon. Because there’s no chemical reaction going on, they don’t degrade like lithium-ion batteries, which rely on rare-earth metals and can end up in landfill after two years. This means that you can charge them much more quickly – a five minute charge for one of Belgrade’s buses can carry it up to 18 kilometres.

    There are two reasons supercapacitors haven’t yet replaced batteries in our electric cars and electronics: they hold less energy in the same amount of space, and they can’t hold it for as long. A fully charged supercapacitor can leak down to empty in hours, rather than days.

    Why graphene hasn’t taken over the world...yet
    Verge Science
    Published on Jul 10, 2018
    Graphene is a form of carbon that could bring us bulletproof armor and space elevators, improve medicine, and make the internet run faster — some day. For the past 15 years, consumers have been hearing about this wonder material and all the ways it could change everything. Is it really almost here, or is it another promise that is perpetually just one more breakthrough away?
