It really doesn’t seem like it should be all that difficult to keep your phone charged, but life gets in the way sometimes. You meant to plug it in before bed, but you got distracted, and now you’re headed out the door with a phone that won’t last half the work day. There isn’t nearly enough time to charge it before work because rapid charge is only so rapid.

However, thanks to researchers at the University of Waterloo, we’re one step closer to batteries that can charge in a figurative blink of an eye. The key to it are supercapacitors, which are a promising alternative to traditional lead-acid batteries. The supercapacitor uses thin sheets of graphene as conductors, and by coating those sheet in an oily liquid salt, it keeps the sheets from stacking together, therefore increasing the surface capacity and the amount of charge they can hold.

You can read all the scientific details in their press release, but for the layman, this is one step closer to readying supercapacitors for their eventual takeover of traditional batteries.
