Innovation, inventions, are the order of the day in technology. And if a new improvement in the screens, what if a new way to assemble the cell phones … And the batteries? A new way of creating them dispenses lithium in favor of graphene . In this way, everything seems to improve over lithium.
Batteries, after all, are the most important components of the modern technology we use every day. Not just cell phones, wearables or even cars. Also in fields such as security against blackouts or storage of renewable energy.
But how much time do we take with this graphene?
When graphene was discovered, something as simple as a carbon sheet of a single thick atom, came out everywhere. Graphene looked like it was going to change the world and also promised us improvements in batteries . And where are these improvements? See, I see them.
Year 2013, We told you that graphene batteries could get. These batteries would charge faster and we would have a longer life thanks to its capacity. Since then, we have seen capacity improvements in lithium batteries. Also cell phones that removed some things ( * ahem * Jack * ahem * ) to put bigger batteries. In fast-load technologies like Qualcomm QuickCharge, have appeared to improve the times.
We jumped to 2015 with graphene already forgotten. In addition to lithium (Li-on) ions, we began to monitor other compounds based on lithium and magnesium . It continues to look for the same: faster loading, less degradation over time and more capacity. But we look to the future in search of these miraculous solutions.
Most recent, 2016. Huawei introduced in collaboration with the Watt Laboratory of Japan, the application of graphene to lithium batteries. This way, they have managed to maintain a higher temperature and for a longer time. But they were not graphene batteries, we were talking about a lithium battery reinforced with graphene.
Samsung advances on batteries with "graphene balls"
Samsung has managed a way to create graphene batteries using "graphene balls" or "graphene balls". We are talking about batteries that try to replace lithium completely, and not as an addition to these to improve them. Recall that these began to be marketed in 1991.
The Samsung Advanced Technology Institute (SAIT) along with Samsung SDI (the part of Samsung that manufactures batteries) and a team from Seoul University of Technology are those who have achieved the achievement. They formed with graphene, a thin layer of carbon, small 3D shapes similar to dwarf popcorn. These "balls" would be the ones would be used in the new graphene batteries as an anode and cathode instead of lithium.
It is not surprising to see Samsung advancing in the field of graphene. As a major electronic manufacturer, it seeks to achieve greater autonomy for its products. Samsung SDI is one of the world's leading manufacturers of batteries and by 2014 they already had a method to produce large-scale graphene .
How do graphene batteries improve? These batteries developed by Samsung can work in higher temperatures (60 ° C), can be charged 5 times faster and have 45% more capacity . In addition, degradation also improves, retaining greater capacity over time. Let's review what these improvements mean.
