Graphene lithium ion exchange battery, electric car charging only one minute!

The United States has developed a new type of energy storage device. The United States has developed a new type of energy storage device, a substance that does not seem to be compatible with batteries. This has become the key to breaking the bottleneck of battery technology. Researchers at Nanotek Instruments in Ohio, USA, have used the characteristics of lithium ions to quickly and massively shuttle between the graphene surface and the electrode to develop a new type of energy storage device that can shorten the charging time from the past few hours to Less than a minute. The research was published in the recently published 'Nano Letters.' Battery charging performance has become the biggest challenge for the development of electric vehicles. As we all know, electric vehicles are regarded as the future development direction of vehicles because of their clean and energy-saving characteristics. However, the important technical bottleneck facing the development of electric vehicles is battery technology. This importantly reflects the following aspects at present: One is the energy storage density of the battery, which refers to the amount of energy stored in a certain space or mass material, and the problem of how far an electric car can run with one charge. The second is the charging performance of the battery. People hope that the charging of electric vehicles can be completed in a matter of minutes, just like refueling, but the problem of time-consuming is always an insurmountable obstacle for battery technology. The charging time of several hours at every turn discourages many people who are interested in electric vehicles. Therefore, some people call the charging performance of electric vehicle batteries the real bottleneck in the development of electric vehicles.
