Chemical Batteries To Die Soon ? Graphene Battery Future.
As exploding batteries in mobile phones, computers and headphones continue to make headlines researchers at Swinburne’s Centre for Micro-Photonics are one step closer to producing commercially viable, chemical-free, long-lasting, safe batteries.
The team are developing a Carbon Based,Thin and environment Friendly Batteries .
It is called Bolt Electricity Storage Technology (BEST) battery – a graphene oxide-based supercapacitor offering high performance and low-cost energy storage.
Graphene material is very porous, which gives it a hugely increased surface area on which to store electrical charge.
They are aiming to create a supercapacitor that could more efficiently collect, store and discharge the energy collected by solar cells.
Chemical batteries are toxic to the environment. The chemicals degrade as they are used, producing spent, un-rechargeable batteries as waste products. Modern uses require batteries that charge and discharge quickly,too.
The Graphene Batteries Made has an improved ability to quickly charge and discharge energy, and it can store signiﬁcant power for longer. It’s safer than current battery technology, as it is able to function without overheating or resulting in explosions or fires.
The porous graphene surface stores charged atoms (ions) and moves them from one electrode to another.
“In this process, no ions are being generated or being killed,” Dr Lin says. “They are maintained by charge and discharge, and are just moved around. Moving ions doesn’t degrade the supercapacitor, so it can charge millions of times, in theory. Usually, a supercapacitor can work for at least 10,000 life-cycles.”
