What is Graphene Batteries? How it will change the future of world?
January 19, 2020
The technology is growing day by day and we are using latest technologies in our daily life as a favor of life. The latest techs are being used by from a daily folk to students and Governments. There is no doubt that someone is not aware of under-display fingerprint scanner in their smartphones. Just like that almost every latest technologies are being discussed among the tech geeks.
While doing our daily works, we often charge our smartphones everyday. Sometimes we do it like thrice a day or more but don’t remember or just take it as granted. But what if we had not have to charge our smart devices frequently? What if our smartphones would go long as two or three days or let’s say a week? Would you believe me if I say it’s possible? Am I joking? No, but strangely it’s even more real than possible.
Well, scientists have told that the graphene technology can do this surprise at ease and they are working on it now. But this technology is currently at development stage. Since the development is in progress, graphene might replace the li-ion (lithium ion) batteries in future when the graphene battery technology gets ready commercially. So, graphene is just not removing current power technologies yet. It needs some time definitely.
What is Graphene?
Well, before knowing about the upcoming future technology of power source, let’s now firstly know what graphene is.
Briefly, graphene is a two dimensional composition of carbon atoms that is structured and bound promisingly to each other in a hexagonal or honeycomb like shape. The unique speciality that makes this compound unique is it’s two dimensional (2D) shape. For the one atomic layer shape, graphene carries some of very interesting properties. It has excellent electrical and thermal conductivity, higher strength, higher flexibility and lighter in weigh than copper which makes graphene – the most conductive metal element present on earth.
Now, when it comes to battery, graphene batteries will make a major breakthrough in tech world. Because of graphene’s capabilities, the best ideal use of graphene batteries will be on smartphones and electronic cars.
Graphene can be used as a “Supercapacitor” in such electronics. Supercapacitors can store current just like the traditional batteries but it can charge and discharge quickly. So, a smartphone with graphene battery can be charged faster than typical fast charge solution.
Problem with graphene battery
The major problem ahead for making a graphene battery is it’s mass production. While the graphene battery technology is still under construction, it is also very problematic. The production of the conductive element is prohibitively very high at current scenario but the research can make it reality and under the hood.
Previous production projects of graphene batteries
In 2017, Samsung Advanced Institute of Technology (SAIT) developed a graphene ball, a battery material that increased the storage capacity upto 45% and charging speed has been increased five times than the typical lithium-ion batteries.
Before we head towards the plus points of graphene batteries, lets first briefly know how a rechargeable li-ion battery works.
A rechargeable lithium-ion battery is made with power generating components called cells. Each cell has basically three main compartments. They are positive electrode, the negative electrode and one kind of chemical between them called electrolyte. The positive electrode is connected to battery’s + terminal and the opposite, negative electrode is connected to the – terminal. In a brief sentence, when using the battery or let’s say during discharge period, the ions travel through the electrolyte from the negative electrode to positive electrode. While charging, the process happens in opposite manner.
Now, graphene batteries are also made in same manner but has different characteristics. While the internal decoration is nearly same but for the material (graphene), the battery offers higher electrical conductivity than typical lithium-ion batteries. The process lets the battery charge faster too.
Graphene is also a lighter element and a battery, made with graphene will be lighter than li-ion battery. That means more power at low capacity storage. Lithium batteries also hold more current that usual li-ion batteries. E.g. where a one kg lithium-ion battery can store upto 180Wh of power, a one kg graphene battery would store upto 1000Wh of power. That’s astonishingly awesome.
What about safety and other cautions?
Graphene batteries will rise a question while using and that is if the graphene batteries carries better safety with it. And the answer is yes, partiality. Partially, because nothing in the world is perfect and this can redirect to the point, safety. But at the same time, graphene batteries are more reliable than li-ion batteries. We already marked lithium-ion batteries as a safe power source but we also have seen some cases of li-ion batteries, being exposed. It might be some manufacturing fault or may be any usage fractures that leads a lithium-ion battery’s cells to join each other without any solution. But in past, lithium batteries have been destroyed while using in a phone. There we can say graphene batteries would be more safe because it’s more stable, flexible and has more heat conductivity.
Well at last, it’s safe to say that graphene would possibly lead the DC power source in near future. May be we will see, almost every companies are using graphene as their primary power bank. Cars, mobiles and others devices would rather use it’s technology to enrich their products and will make it safer. But to reach at this day when these all will happen, we got some time to talk about other technologies.
