Laser-induced graphene-made supercapacitors might one day replace battery power as we know it. In case you're not familiar with the wunderkind of organic matter, graphene is technically a thin layer of pure carbon chock-full of carbon atoms latticed together in a hexagonal patchwork; but the organic material is also low-cost to produce, 207 times stronger than steel, while being the thinnest compound known to mankind and one of the best electrical conductors around to boot.
