if you were to ask an average physics student about graphene, he would probably tell you about its potential to be used for its structural properties, more specifically its unsurpassed strength to thickness ratio. However, graphene also has many unique and desireable electrical traits. Because graphene is extremely thin, relatively strong, and conductive, you can use sheets of it as plates for a capacitor. the advantageous thing about a graphene capacitor is that you can fit a lot of plate surface area into a small space, giving the capacitor a much higher energy density than conventional batteries. With this technology inside a common electronic device such as an ipod, for the same storage space one could theoretically charge it to full capacity in as little as three seconds, the charge lasting several weeks. although this technology is still far off, one can imagine how mch it would change our lives.
