Going on a trip and carrying your tablet or smartphone charger is common and essential. Even when we sleep out one night, we have to carry a charger so as not to be isolated from our contacts. The problem is in the poor autonomy of Li-Ion batteries or lithium-ion that, although they have given us a solution for years, as the devices advance and their power increases, they remain more and more obsolete. An investigation carried out in California on graphene supercapacitors It could provide us with batteries that charge infinitely faster and take up much less space.
The finding has been made at the University of California, Los Angeles (UCLA) in its Henry Samueli School of Engineering and Applied Sciences. Professor Henry Kraner has led a project that has succeeded in creating small-size graphene-based supercapacitors. its loading speed is brutalSpecifically, between one hundred and one thousand times faster than that of current batteries. It has been said that it could charge a smartphone in 5 seconds, but it is probably an exaggeration.
As we said, its size is also very small. These batteries can be so fine with a carbon atom. And it is that graphene has this dimensional quality, it is manufactured in sheets of this thickness and then superficially they can be extended as much as you want. Taking advantage of this quality could be done much thinner and lighter devices.
The most curious thing is that the manufacturing method that they have used in the laboratory could be transferred to any house. They have simply used a DVD recorder and a liquid composed of graphite oxide dispersed in water. They were able to create 100 micro supercapacitors on a DVD in less than 30 minutes.
The research team has already contacted manufacturers to give it a commercial outlet so that one day we can enjoy this technology. This advance is not only applicable to mobile devices, but could also extend to electric cars.
At the moment, it cannot be said that we will see this soon but it is good to know that progress is being made in solving real life problems.

Well the graphene thing seems incredible. And I hope it's not like the typical movie that nominates a gazillion Oscars and then doesn't win any.

You're right. How many times have we had our illusions, but in this matter there are many interests involved and those who really know about these things on a technical level are few. Fingers crossed, because the batteries for tablets and smartphones are a lot.
