Graphene Battery, the Wonder Material

In the near future, we are going to witness the era of Electric Vehicles. Already, in most of the countries, electric vehicles started doing rounds on the roads. But in India, it is slowly emerging. By 2020 some companies like Maruthi Suzuki, Tata Motors, Jayam Motors, etc. planning to launch their electric vehicles in the market. So, if they will get good reviews, then the remaining companies also will come forward to manufacture Electric vehicles with their inspiration. Thereby, Electric Vehicles can pick up their momentum in India too and Graphene battery technology is going to spread on a larger scale. Let’s dive into the deep discussion to learn more about it.

What is Graphene Battery? 




Whenever we talk about Electric vehicles, we must keep an eye of the battery that is used to propel an electric vehicle forward. Usually, Li-ion and Lithium polymer batteries are used in Electric Vehicles in common due to their high energy density compared to their weight. Li-ion batteries require low maintenance. So, due to these supporting features, Li-ion batteries occupied a significant place in the EV industry. However, like all technologies, Li-ion batteries have their disadvantages too.

Some of the major disadvantages of Li-ion batteries include short cycle lives, significant degradation with age, the cathode material used is also somehow toxic and harmful, they pose a fire safety risk if punctured or charged improperly and they won’t supply charge when it is extremely cold and heaters must be there to heat them etc.  So, due to these numerous disadvantages, the manufacturers are looking for the right alternative to replace the Li-ion batteries.

Graphene Battery, the Wonder Material

In this scenario, Graphene battery technology comes into the picture. Graphene is a material composed of pure carbon material, similar to graphite but with characteristics that make it extraordinarily light and strong.




It is one of the most conductive materials for heat and electricity. In 2004, two of the professors from the University of Manchester isolated a single atomic layer of Graphene for the first time. With this progress, studies on Graphene have advanced.

Graphene-based battery which will be charged fully in 12 minutes, compared to an hour for an ordinary battery. Graphene enhanced Li-ion batteries show phenomenal characteristics such as longer lifespan, higher capacity and faster charging time, etc.

  • The Graphene battery comes up with more energy density which is five times that of the Li-ion battery available in recent times.
  • The graphene batteries are considered to be safer than Li-ion batteries as there is no risk of explosion. As a result, lighter protective covers can be used and thereby the weight of cars get reduced drastically.
  • And graphene batteries are cheaper when compared to Li-ion batteries.

These super features of graphene made it superior to Li-ion technology. So, one can adopt these graphene batteries instead of using Li-ion batteries it is much more beneficial and can change the course of the entire EV industry.
