Carbon batteries will change our lives [Technology]
posted February 27 2013 21:01.10 by Giorgos Lazaridis




How about charging your telephone in 3 seconds? Your car in a few minutes? How about disposing your batteries in the trash bin without worrying about the environmental impact? How about batteries made of graphite???

Actually what4 we're talking about here is graphite super-capacitors. A battery is a device that stores an energy in the form of chemical energy, while a capacitor stores energy in the form of an electric field. S super-capacitor does exactly that, but many times more efficient.

A capacitor is composed by two plates separated by a non-conductive material. These plates are completely isolated. When a voltage is applied across these plates, an electric field is generated. When we remove the external voltage source, the stored charge remains across the plates.

Graphite can replace the metallic plates. This means that we can make graphite plates as thick as one atom (!!!). Thus, we can have hundreds or even thousands of these plates inside a small capacitor, able to store enough energy for your laptop.

As an added feature, when a capacitor is empty and we apply voltage across its plates, the time it takes to fully charge is literally a few seconds.
