Graphene-LED Setup Can Act As A Supercapacitor

Several scientific discoveries were made by accident, and we may just be in the middle of one.

Cairo University graduate Maher El-Kady had unintentionally connected a small piece of graphene to an LED with a wire, causing the graphene to act like a supercapacitor, which can store large amounts of electricity.

Capacitors till today have not been able to store as much electrical energy as conventional batteries, but because of this discovery, capacitors could now rival batteries in terms of storage capacity, without having to contain dangerous chemicals like acids, alkalis and toxic metals.

The UK National Energy Grid – A Story of Islands, Trading, and Energy Storage

As first seen in Energy Global, grid software acts as a modern-day map, helping to chart and navigate today’s energy grids; software engineers are tasked with carefully delineating how each region’s energy markets operate. However, looking more closely at energy markets makes clear how unique each market is – each defined by different topography, resources,…
