With the widespread popularity of mobile phones, more and more people who control mobile phones and bow their heads have begun to appear. For patients who use mobile phones heavily, it is quite annoyed that the mobile phone is out of power, and the power bank is a serious problem for these mobile phones. Use the patient’s lifesaver. Not only is it small and portable, but it can also be carried anywhere. But have you ever thought that maybe one day, we can no longer need the power bank?
In fact, what determines the fate of the power bank is directly determined by the charging speed and battery capacity of the current mainstream mobile phone batteries. As more and more mobile phone manufacturers launch “super fast charging” and make larger capacity batteries When the time comes, the importance of the power bank is bound to be greatly reduced until it finally becomes insignificant.
At present, the mainstream battery used in mobile phones is lithium battery. Since 1991, lithium batteries have been used for commercial use and are standard for electronic equipment. It has only been less than 30 years. time. However, many people now feel that the development of this technology has reached its limit, and people should continue to look for new technologies. At this time, graphene technology began to enter people’s attention. Tests have shown that graphene’s conductivity and durability are very good, which can completely strengthen lithium batteries and make lithium batteries more powerful.
Recently, some media reported that Samsung Electronics’ research and development department successfully synthesized a “graphene ball” that can be used to extend the life of lithium batteries and speed up their charging. The graphene ball material can increase the battery capacity by 45% and the charging speed can be accelerated by 5 times.
That is to say, the existing traditional lithium battery takes about 1 hour to be fully charged, but the lithium battery after adopting the new technology can be fully charged in only 12 minutes. Moreover, it is not only superior to traditional lithium batteries in terms of capacity and speed, but also to know that this new type of synthetic lithium battery can also keep the temperature of the battery at 60 degrees Celsius, which is in line with the current requirements of new energy electric vehicles. There are broader application prospects.
According to relevant research data, this graphene battery is a new energy battery developed by utilizing the characteristics of lithium ions moving rapidly and in large quantities between the graphene surface and the electrodes. When the conditions are right, the new battery compresses hours of charging time to less than a minute.
Due to the huge application prospects of graphene, many countries have established graphene-related technology research and development centers, tried to use graphene for commercialization, and then applied it in industry, technology and other fields. The European Union and the British government have spent a lot of money to build graphene-related scientific research institutions .
Moreover, my country’s graphene mineral reserves are very rich, and the price is very low, so we can see that the application of graphene in my country will certainly be very extensive in the future. At present, Huawei mobile phones have started research on graphene batteries in 2015, and the application of graphene in my country will also be very extensive in the future. At present, Huawei can directly apply the research results of this project to Huawei’s consumer electronics products and mobile communication equipment. The latest Huawei mate20pro is equipped with this technology.
With the continuous deepening of research, technical problems will be overcome one after another, and graphene batteries are expected to be popularized rapidly, bringing new changes to the industry. At that time, maybe the power bank will gradually disappear and only exist in the memories of a generation.
