Graphene batteries: characteristics, advantages and disadvantages

Science advances and seeks to adapt to the demands required by society. The investigation of graphene batteries will make possible an ecological transition, since these could replace the use of fossil fuels. Some of the most outstanding characteristics of graphene batteries are:

• Energy density: This type of batteries get to achieve an energy density greater than lithium batteries. That is, they can store much more energy.
• Load speed: Graphene batteries need less load time. With this type of battery in approximately 10 minutes, an electric vehicle or a mobile phone could be loaded. If you are curious to know if it is worth investment in an electric car? Visit this article.
• Security: The use of these batteries is safer, since they do not use liquid electrolytes. In this way the explosion risks are reduced.
• Flexibility: Thanks to the composition of carbon atoms in a hexagonal form, graphene is very flexible and thin, so it can adapt to the conditions according to the requirements.
• Useful life and stability: The graphene gives a structural stability that causes the volume of the anode of this type of batteries not to change every time a load and discharge cycle occurs. Thanks to this, the useful life of graphene batteries is much greater than compared to what other types of materials can offer.
• Environmental improvement: Graphene batteries can be very helpful in the ecological transition. The fact of not having to be replaced so often, is already a point in favor in the care of the environment. In addition, graphene can produce energy if exposed to sunlight, so it also enters the list of green energies. It should be added that, at the time it is used in the automobile sector, they can replace fossil fuels. You can read more about the subject in these other articles about what solar energy is and what fossil fuels are and how they formed.

Among the main advantages that graphene batteries will have when they are totally operational, the following can be mentioned:

• The energy density of these will be much greater.
• He load time is reducedsince the load cycles they will have will be 100 times faster than those we currently know.
• They will offer greater security.
• Its weight is much lower and will occupy up to a 30% less space.
• It will give electric vehicles an autonomy of up to 800 kilometers away.
• It has one Useful life 4 times higher than lithium batteries.

Although there are many advantages that graphene batteries can offer, they also have their disadvantages. Some of them are:

• The graphene It is not a magical material: Researchers behind the graphene study are trying to find out all potentials of this material. However, in practice everything they discover is applied.
• There is Difficulties for commercial applications: Despite all research and the more than 6,000 scientific articles that exist of this material, there are still no products in the market with this material.
• The graphene it’s a Unstable material: Graphene is an unstable material, so treating it and working with it is not a simple. Operations to work are not simple, require a lot of time and a large economic investment, so all companies are not available 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 exhausted, has caused graphene investigation to go to the forefront.

Not for having mentioned disadvantages we must 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, mobile phones or smartwatch and activity bracelets and even for electric cars as well.
