Tech-savvies believe that we’d genuinely be futuristic when we have easy access to Graphene batteries. A battery may sound like a simple thing to many, but Graphene batteries could change the game forever.
Scientists say that Graphene batteries will genuinely create a futuristic society where your devices can run up to days and weeks without charging.
A Graphene Battery in a nutshell
Packed together in a honeycomb structure, graphene is a carbon atom composition that has a thick two-dimensional atomic layer. The 2D structure of this composition allows graphene to be highly flexible, stalwart, and light in weight, as well as offer exceptional electrical and thermal conductivity that is even better than that of copper – an element that is known to be most conducive.
Graphene battery vs your regular battery
The battery that we use in our portable devices is made with lithium-ion, also known as Li-ion. A lithium-ion battery has a similar structure to a graphene battery. Both the batteries have two conductive plates coated in an electrolyte solution, but the characteristics of both batteries differ on a considerable margin.
As mentioned earlier, graphene’s electrical and heat conductivity is higher than the most conducive element copper. Thus, it’s conductivity surpasses that of Lithium-ion as well. As a result, a device can be charged a lot faster as current travels more quickly. This high conductivity also extends the life span of a battery as they cool down faster.
A regular battery’s charging rate doesn’t remain consistent throughout its lifetime. A lithium-ion battery starts faster, tires out, and then delivers slower current, reducing the rate of charging. On the other hand, a Graphene battery offers linear charging rates, which means that this type of battery doesn’t tire out.
“Graphene batteries can make batteries charge faster and dissipate heat more effectively. This has big implications. It means power tools don’t overheat as quickly. It means home appliances serve families better, and for longer. And it eventually means [electric cars] can charge faster.” Chip Breitenkamp, VP of business development at the graphene battery company said.
Most importantly, Graphene batteries are safe. The incidents of smartphones burning up, overheating, and damage due to overcharging are overly familiar. Users can avoid these unfortunate events by opting for Graphene Batteries instead. There’s virtually no chance of overheating Graphene batteries as they are more robust than lithium-ion ones.
