The development of a graphene super battery in the United States to charge mobile phone only 5 seconds

Before I introduce today's protagonist, I'll talk about a little joke I heard the day before yesterday. A man back to the northeast home, found that the ipad can not charge, anger after looking for a sale, the results were told, in the outdoor cold, please put the blanket warm and recharge. He went home for a try, Emma. Maybe you live in Hainan, mobile phones and tablets can not be frozen bad, then the next question, no matter where you are, certainly will not escape-battery power is not enough! Yes, the damn battery, the morning out clearly full, the result is half a day, the electricity is running out, and, every time in the critical moment without electricity, as if mean with you. What to do? Find a place to recharge? Well, if you want to be filled, wait 2 or 3 hours first. With mobile power? OK, but the bag has a lot of mobile phones, tablets, notebooks, you are not enough weight? Well, according to the General screenplay, this time, our hero-super battery! Is the graphene chart misplaced? No, before the superhero comes out, please allow me to end up with a little foreplay. This can be said to be a superhero energy source, the famous graphene (structural map). If you have had two meals in the tech community, I think you've heard it more or less. Never heard of it? Hurry up under the popular science, lest go out and say hello to people. According to the scientific point of view, graphene is a carbon atom of a monolayer structure of new materials, carbon atoms in a complex form, composed of hexagonal lattice-shaped film. The simple point is that there is only one two-dimensional nanometer material with a thick carbon atom. Graphene is the world's thinnest, but the most hard material, its structure is extremely stable, high thermal conductivity, very low resistivity, electronic migration speed is very fast, so it can be said to be the most ideal two-dimensional nano-materials. If you don't understand what the above two paragraphs say, it doesn't matter, those are for you to install Bility time use, if you do not need, then look at its use, such as our protagonist, Super battery. Micro-graphene supercapacitor This is the miniature graphene supercapacitor developed by a research team at the University of California (the small black patches on the disc), the most magical part of which is that it is charging and discharging at 100--1000 times the speed of conventional batteries. What does that mean? If you use it on your mobile phone, it takes about 5 seconds to fill it, and if you buy a new Tesla, it will take about 5 minutes to recharge the electricity. More perverted, because of its elements and structural characteristics, your cell phone power use can be used as a "week" as the basic unit, and, whether you are in the Arctic or the Sahara desert, there is no need to worry that it will be too cold or too hot to strike. However, whether foreign or domestic, the current graphene super battery is still in the laboratory stage, in addition to technical stability, another key reason is that graphene too expensive! Yes, even with today's preparation process, the appearance of better graphene, still can sell to 2000 yuan per gram, to take so expensive things to do batteries, it is only true tyrants, can be completed by the private customization. Of course, the manufacturing process will continue to improve.。 For example, in China, the Chinese Academy of Sciences Ningbo Materials in cooperation with the Ningbo Ink-West Technology group, to promote the large-scale production of graphene technology, I believe that in less than five years, the manufacturing cost of graphene, will fall to the level of ordinary people I can afford. At that time, I think the super battery will also enter the popular fast road, then, when you call a friend to borrow money, you do not have to be his "cell phone no electricity" as an excuse.
