Graphene batteries for electric cars can revolutionize the conception that we currently have regarding the automotive world of the future. Graphene is defined as a monolayer of carbon atoms that are hexagonally and tightly packed in a 2-D lattice.
The high quality of 2-D glass makes graphene present great electronic properties, which is why it is being studied in depth in the application of Li-ion batteries. In this way, a clean and renewable source of power is being achieved, which could replace fossil fuels.
If you want to know more about graphene batteries, their characteristics and what are their advantages and disadvantagesContinue reading this interesting Green Ecologist article in which we explain it to you in detail.
Graphene characteristics
Science advances and seeks to adapt to the demands that society requires. Research on graphene batteries will make an ecological transition possible, as these could replace the use of fossil fuels. Some of the most outstanding characteristics of graphene batteries are:
- Energy density: this type of battery achieves a higher energy density than lithium batteries. That is, they can store much more energy.
- Loading speed: graphene batteries need less time to charge. With this type of battery, in about 10 minutes, an electric vehicle or a mobile phone could be charged. If you are curious to know if it is worth the investment in an electric car? visit this article.
- Security- These batteries are safer to use as they do not use liquid electrolytes. In this way the risks of explosion are reduced.
- Flexibility: Thanks to the composition of the carbon atoms in a hexagonal shape, graphene is very flexible and thin, so it can adapt to conditions according to requirements.
- Shelf life and stability: graphene gives a structural stability that makes the volume of the anode of this type of batteries does not change every time a charge and discharge cycle occurs. Thanks to this, the useful life of graphene batteries is much longer than if it is compared to what other types of materials can offer.
- Improving the environment: Graphene batteries can be of great help in the ecological transition. The fact that they do not have to be replaced so often is already a plus in caring for the environment. In addition, graphene can produce energy if exposed to sunlight, which is why it also enters the list of green energies. It should be added that, at the time it is used in the automotive sector, they will be able to replace fossil fuels. You can read more about it in these other articles on What is solar energy and What are fossil fuels and how they were formed.
Advantages of graphene
Among the main advantages that graphene batteries will have when fully operational, the following can be mentioned:
- The energy density of these will be much higher.
- The charging time is reduced, since the charging cycles that they will have will be 100 times faster than those we currently know.
- Will offer greater security.
- Their weight is much less and they will occupy up to a 30% less space.
- It will give electric vehicles a range of up to 800 kilometers away.
- Has a 4 times longer service life than lithium batteries.
Disadvantages of graphene
Although there are many advantages that graphene batteries can offer, they also have their disadvantages. Some of them are:
- Graphene it is not a magic material: the researchers behind the study of graphene are trying to find out all the potentials of this material. However, in practice not all that they discover applies.
- There are difficulties for commercial applicationsDespite all the research and the more than 6,000 scientific articles that exist on this material, there are still no products on the market with this material.
- Graphene it is an unstable material: graphene is an unstable material, so treating and working with it is not easy. The operations to work it are not simple, they require a lot of time and a large economic investment, so that all companies are not within reach or willing to invest.
- His market entry It is slowing down: the material has been abandoned for decades, that is, it did not have the interest of the scientific community to be studied. Surely the fact that lithium reserves are being depleted has brought graphene research to the fore.
Not because we have mentioned the disadvantages, should we forget that graphene is a material that, in the future, can help us a lot when used in a large number of devices. We could use graphene batteries for electric motorcycles, for mobile phones or smart watches and activity bracelets and even for electric cars as well.
