We live our lives through portable devices, and the race is on to create better energy storage for those devices. Could graphene supercapacitors be the holy grail?
So before I can explain how super capacitors will fix this, let’s back up and explain how batteries work in the first place.
To make it simple, batteries work by moving electrons from a negatively charged material called an anode to a positively charged material called the cathode, and the device siphons off those electrons to power the device.
