Samsung Graphene Battery – The Battery of the Future for Smartphones
Have you heard about graphene batteries? How do they sound? Strange or familiar? Well, the good news is that Samsung is set to release a phone using this battery by this year or 2021. What do you know about these graphene batteries? Here is a rundown.
Graphene Battery Breakthrough
Graphene, which is made of a sheet of carbon atoms bound together in a honeycomb lattice pattern, is largely recognized as a “wonder material” as a result of the myriad of astonishing attributes it holds. flexible with a large surface area, it is a potent conductor of electrical and thermal energy, extremely lightweight chemically inert. Despite being eco-friendly and sustainable, it has unlimited possibilities for numerous applications. In the field of batteries, when conventional batteries are enhanced with graphene, they tend to improve on their capacities.
Graphene is 100 times better than copper and is more effective in conducting electricity. It is also possible 140 times faster than the silicon used in the current lithium technology and that is responsible for fast charge.
Batteries and Supercapacitors
Out there, there are certain types of batteries that are able to store a large amount of energy, but they are very large, heavy and at times release energy slowly. The use of graphene has exciting new possibilities for energy storage jus as it has high charge and discharge rates upon being economically affordable. Graphene-improved performance by blurring the conventional line of distinction between supercapacitors and batteries.
Although the graphene batteries are not in use yet it has been to have exciting potentials and will hopefully yield good results in the future December 2018, India-based Log 9 made it known that it is working on graphene-based metal-air batteries, that can lead to electric vehicles that run on water. The metal-air batteries use metal as an anode, air (oxygen) as cathode and water as an electrolyte with a graphene rod used in the air cathode of the batteries. The cathode material has to be porous to let the air pass since Oxygen has to be used as the cathode, a property that made graphene to excels. Interestingly, the graphene used in the electrode can increase the battery efficiency by five times at one-third the cost. Incredible!
Samsung, In November 2017, developed a unique “graphene ball” that could make lithium-ion batteries last longer and even charge faster. According to the Samsung Advanced Institute of Technology (SAIT) using the new graphene ball material to make batteries will not only increase their capacity by 45% but also make their charging speed five times faster. Also, the Samsung battery that will use this graphene ball material will be able to maintain a temperature of 60 degrees Celsius that is required for use in electric cars.
Samsung does not just want to end up with the graphene batteries for phones only, they intend to use it for their headsets too. Graphene batteries are better than silicone so the earlier Samsung starts using it, the better for all of us.
