On the SEAS blog we have already talked about graphene on several occasions, for example, you can see in this interesting post by our professor Agustín Arnedo, some of its main properties and characteristics. In this article that we publish today, we will focus on its use in batteries. Let us remember that graphene is a substance that is produced from carbon, which is one of the most present elements in nature. Depending on how the carbon atoms are distributed, different substances can be formed and presented in different forms. Graphene is achieved when carbon particles are grouped together in a sheet so thin that it is the size of an atom, and in the shape of hexagonal cells, similar to a honeycomb. It is a very dense substance. Although graphene has been known since the 1930s, it was not until 2004 when scientists Novoselov and Geim managed to isolate it at room temperature. For this discovery they would be awarded the Nobel Prize in 2010.
Since then, rivers of ink have flowed about the so-called “ God material” because of the infinite possibilities it promised. 2D Graphene Modeling SEAS Blog Possible Myanmar Email List fields of application of graphene Graphene is extracted from one of the most abundant materials on earth and has great properties: resistance, superconductor, energy accumulator, etc. Therefore, it has great potential at an industrial level and for a wide range of everyday uses. Graphene can be applied in the manufacture of cars, smartphones, speakers, music equipment, medical prostheses, graphene batteries, etc. Airplanes could be made stronger and safer and buildings with better resistance and insulation properties could be constructed. But in the field where, for now, graphene has a more promising use and that is more developed on a practical level, it is in electronics and, above all, in batteries . Graphene batteries: a great qualitative leap in energy accumulation New graphene batteries are beginning to appear on the market and are expected to end up replacing lithium batteries in a few years.
The big problem with lithium is that it is a scarce material and its extraction is expensive and has a great environmental impact. In addition, the life of lithium batteries is very short. Although there has been some improvement with fast charging systems, lithium batteries last only a few hours: barely a day in smartphones and a few minutes in other devices with higher consumption such as drones. Technology has evolved a lot in recent years. A real revolution is taking place in the field of drones and smartphones. But the weak point and the one that causes the most frustration to users is the poor battery life. The equipment is becoming more powerful every day and has more features, but the batteries are not evolving at the same pace, they seem to have become stagnant and unable to respond to the increasingly demanding demands. Materials Course Graphene batteries for drones Currently, the drone sector and its future development or application in different fields is being held back by the problem of batteries. Due to the weight, dimensions and the capacity of the electric batteries used today, the duration of the flights and the services that can be performed with drones are limited. That is why RPAS (drone) manufacturing companies are starting to use graphene batteries to increase their capacities and bring better products to the market.
