A wide range of applications for graphene batteries

Graphene super battery: Or a company in Beizhakou, Tianjin that can charge in 6 minutes is experimenting with a super battery, claiming that this battery can shorten the charging time of traditional electric vehicle batteries from 5-6 hours to 6-10 minutes. What makes such a great battery? Answer: Graphene! Mi was wrong, fake technology controlled Xiaobai here, and I was on stage with Lily again~~~Okay, don't. What is the graphene used to make super batteries? The author is here to give you a brief analysis of the science. Graphene is a two-dimensional crystal of carbon atoms, only one atom thick, exfoliated from graphite. It sounds difficult, but in short, it is a very, very thin crystal separated from graphite. In 2004, two physicists from the University of Manchester in the United Kingdom successfully separated this crystal from graphite and proved that it can exist independently. The two scientists won the 2010 Nobel Prize in Physics. As long as the thickness of graphene is one atom, its strength is 200 times that of the most advanced steel, and its flexibility can reach 20% of standard materials. It is one of the lightest and strongest materials in nature. In addition, graphene is almost completely transparent, only absorbing 2.3% of light, and its density is so high that even the smallest gas atoms (helium atoms) cannot penetrate it. These features make the data available for many applications, including light-emitting panels, light-emitting touch screens, solar panels, etc. Graphene is one of the thinnest, strongest, most conductive, and best conductive new nanomaterials discovered so far. It is called the king of black gold and new data. Scientists even predict that graphene will completely change the 21st century. It may trigger a disruptive new technology and industry innovation, sweeping the world. Now this king of data has also put into processing new energy vehicle batteries. We all know that during the conversion process of chemical energy and electrical energy of the chemical reaction of battery charging and discharging, its own reaction cycle is accelerated, but it can improve the processing data of the battery. A large number of experiments at home and abroad have proved that due to the physical properties of graphene, electrons move faster on the graphene data surface and combine with copper ions faster, that is to say, it can greatly increase the charging speed of the positive battery. According to research conducted by Rensselaer Polytechnic Institute in New York, the charging and discharging speed of graphene batteries is 10 times that of lithium batteries. Of course, graphene is not that good. Industry insiders agree that the equipment and technology used to manufacture graphene are the biggest constraints on the broad market for such data. As mentioned above, the researchers used the method of exfoliating graphene from graphite. Since then, researchers from various countries have studied different graphene preparation processes, but each has its own advantages and disadvantages in terms of quality, cost, and processing rate. In other words, there is no more useful way to obtain graphene data. Therefore, the cost of this type of data is very high, and it is impossible to batch process it in a short time. Graphene has a wide range of applications and unique physical properties, and it is not unreasonable to be called the king of new data. It is true that the high cost of this type of data will inevitably cause constraints, but as the saying goes, the method is always more difficult than the difficulty. The technology advances so fast, the problem may be solved soon. Think about the many benefits of this kind of data for people in the future, and the discussion is also quite motivated!
