Space limit and problems with Load and load tolerance Make the devices we are currently working on lithium ion batteries have serious shortages, especially regarding the limitations of their independence and the useful life they have in terms of charging cycles.
However, in recent years technology has taken a major step since they started experimenting graphene, an asset that could enable our device batteries to solve all these problems, provide longer useful life, new shorter cycles and, in addition, better autonomy.
So, if everything is for profit, why haven't they hit the market yet? Before answering this question, it is important to first define the basics.
What is graphene?
Graphene is only a thick layer of carbon. Although it is made of the same material as graphite in pencils, because its dimensions are so small it is considered to be two-dimensional (space-size), which is why its properties change to what they think of. superconductor electric
This is very important when we know that many of the things we use to make electricity have a certain amount of resistance, which forces us to use larger volumes (for example, to make larger copper cables to generate more electricity) in addition to forcing us to use other methods to reduce symptoms (in other words, resistance, heat is produced and therefore we need heatsinks, to maintain good temperatures).
Internal electrical resistance is the reason why all batteries have what is called «output limit»They cannot win in any way. Some advanced units can shoot up to 20 amps, but at some point they are overloaded, doubling their chances of having problems.
Graphene significantly increases this limit because of it almost a complete lack of internal resistance, which is why it is also heat resistant and it is not necessary to use any type of heatsink. For this reason, it is not difficult to imagine several layers of graphene in a battery, which would mean a much higher pipeline limit, with a higher electrical charge (as it goes) and without any heat or hazard, is it?
Put another way, all this means is that in theory we can build a graphene-built battery-to-charge to efficiently charge and discharge large amperes – and do that without drastically affecting its full length or risk. In fact, if the current claim is correct, graphene can even increase the number of charging cycles it supported the battery.
Graphene can also be limited
The great wisdom of graphene is that it is a large, almost non-flammable transmitter, that it is made of the most common material in the world and therefore does not require a large investment of volatile substances. The bad part is that creating those layers of thick form is a problem for manufacturers, both to achieve it and the technology they need for their production.
In addition, the obstacle is the fact that there are currently no alternatives to using graphene batteries as such, but only in combination with current "upgraded" lithium batteries.
With all that in mind, the leading manufacturers believe that the time has not yet come because lithium batteries are currently continuing to meet expectations, even though they agree that the time will come when their technology reaches the limit and need to invest more. aids in developing this technology that incorporates graphene. In the meantime, they hope to find an easy and cheap way to get them to produce.
Can you get graphene batteries now?
By the beginning of 2020, there are already pioneering companies in the development of this type of batteries, among them Elecjet with its Apollo Traveler and G-Pro «Real Graphene» electric banks, in a sense, using ion batteries. -graphene and that its 2000 mAh version only costs $ 60.
However, besides this there is no commercially available product, including smartphones or laptops, with these type of batteries. Small steps are being taken in this process, but things are going very slowly and commercial use is not expected for a few years.
