Mobile industry has evolved drastically in the last 10 years. From bulky bricks with buttons to zero button experience, everything has changed. With every thing progressing in the smartphone industry, the only tech that hasn’t changed a bit is the battery technology. Battery tech is the one technology where even brands like Apple and Samsung have also not brought any change.
Though there has been a major improvement in charging technology, the battery department on its own has not improved much. The only development we have seen is the change from Lithium Ion to Lithium Polymer. Apart from this, charging technology has improved. We can now get up to 30W charging even in budget devices which was not possible earlier.
In this article, we are going to discuss a revolutionary battery technology that is going to change the scenario drastically, that is Graphene Batteries.

What is Graphene?
Graphene is basically a graphite layer but in 2-D form. It is a layer of graphite that is as thin as the size of an atom. Its atoms are bound together in a honeycomb pattern. This material is nothing less than a marvel. It is a good conductor of electricity and thermal energy and is very strong. Two layers of graphene are so strong that it can even stop a bullet. Graphene is one of the most futuristic materials that was first discovered in 2004 by Professor Sir Andre Geim and Professor Sir Kostya Novoselov of the University of Manchester. The duo won a Nobel Prize for the same in 2010. Apart from the application in smartphone batteries. You can read in detail about it in this article. Including this, 5G is another technology that will drastically improve the way we communicate, more about it in this article.
Graphene Battery Pros: Why is it better than Lithium Ion batteries?
Graphene batteries are a revolution in the smartphone battery industry which has been stagnant for the last 10 years. Graphene batteries are superior to Lithium Ion ones in almost everything.
It is important to note that graphene batteries are not a newer kind of batteries but it will be used as an anode in lithium ion batteries to improve the battery performance and other improvements which we are going to discuss now:
More Charge Cycles

While the Lithium Ion batteries have a charge cycle of 300 to 500 cycles, the newer Graphene batteries will have a charge cycle of 1500 cycles which is thrice the number of charge cycles.
Lesser Heat Generation
Batteries made using Graphene will generate lesser heat even after generating power equivalent to the traditional lithium ion batteries. Currently, there are many kinds of fast charging technology but one common problem that all of them have is heating. The lithium ion batteries heat up when they are charged with higher watts.
This is probably the most remarkable and useful feature of the graphene batteries. While the current generation of 3000mAh or higher capacity batteries takes almost an hour even with the current fast-charging technology, the Graphene batteries will take only 16 mins to fully charge it. In fact, a power bank with 10,000mAh batteries with Graphene will take only 50 mins to charge fully, while maintaining lower temperature than the current crop of batteries.
As a Graphene layer is very thin, the thickness of smartphones is going to be thinner than now. Companies will be able to manufacture lighter as well as thinner smartphones which will give the smartphones even a more futuristic look.
Better battery life per charge
Because of lower heat while charging even with bigger Watts, at a single charge, Graphene batteries will last 1 to 2 days pretty easily. Because of this, the e-waste in the world will reduce significantly.
Graphene Battery Cons
The only con about these batteries is the one which will also fade away as soon as its production increases. The problem with graphene batteries is the increased battery cost by 30% as compared to the current cost. This will increase the cost of the smartphones manufactured. However, this will also decrease as the cost of production decreases with increase in production.
Graphene Battery Manufacturer
Many companies have started manufacturing Graphene based batteries. However, the price of powerbanks using this technology is a bit higher than the normal ones. Currently, the brands selling graphene battery power bank are:
Real Graphene USA LLC
These are some of the companies that have their products out in the market that can be bought right now. Graphene battery power banks from these companies are priced below $100.
Also, as per this article on Samsung’s website, it has developed a graphene-based battery that will charge 5 times faster than lithium ion batteries. The graphene battery, which Samsung is working on, is likely to get launched within next 1 to 2 years.
Graphene Battery Manufacturers in India
There are very few Indian companies using Graphene batteries in their products in India. Only Indian Institute of Science and KAS Tech have been able to work together closely and develop Graphene battery in India, as mentioned here. However, this situation is going to change in the coming years. We can expect large scale production of Graphene and Graphene based products in India within the next 5 years.
Graphene Battery Price
As mentioned above, graphene batteries are priced near $80 to $100. However, this is going to change as soon as the production of the same increases. As the production of the batteries will increase, the cost will go down automatically.
Graphene Power Bank India Price
As of right now, there is no graphene-based battery or graphene battery power bank available in the Indian market. In case you want to buy the same then you will have to import one from other countries. However, when Samsung will start producing Graphene-based products, it is very likely that the same will be available in India.
From the above mentioned information, you must have gotten an idea of how revolutionary this technology is. Apart from batteries, this technology will lead in other fields too, fields where stored power is required in a large amount.
Tell us in the comments section, which feature of the graphene battery you loved the most and are waiting for.
For me, a bigger battery is definitely the one thing I would love to have.
