Graphene - super battery is the future
In the field of electronics, the battery is a very important part, after all, without the battery can not drive electronic products, the battery is equivalent to a person's heart. Therefore, improving battery performance has become very important. The current mainstream lithium battery has dominated the battery for many years, but the lithium battery technology has not been greatly improved. The charging speed, battery capacity, environmental pollution and safety have severely restricted high-tech applications. Therefore, graphene batteries have been favored by scientific researchers, and they have been researched to replace lithium batteries.
Graphene is a two-dimensional material. It is the thinnest and hardest material in the world. Its conductive thermal conductivity is also the best in the world. Its hardness exceeds that of masonry and its breaking strength is 100 times that of steel. At present, many countries are actively developing graphene battery technology, and a research institute like China has developed an aluminum-graphene battery. This battery has a long life, charging 5 times a day, can also charge for 140 years, charging speed is super fast, safety is good, can work normally at minus 40 ° C to high temperature 120 ° C, the battery will not explode in the open flame The fire also has very good flexibility and has great potential in flexible electronics. Like the graphene ball battery in Korea, the battery capacity has increased by 45%, the charging speed has increased by 5 times, and it can be fully charged in 12 minutes. Like the Fisker luxury electric car in the United States, it uses a graphene solid-state battery, which can drive 208 kilometers in 9 minutes and 640 kilometers in full power. This electric car will be launched in 2019. According to relevant personnel, Fisker has been able to upgrade the battery life to 800 kilometers and fully charge in one minute. Of course, this is just laboratory data, and it will take some time to apply it to the actual situation.
Graphene batteries, although using the most excellent and most potential materials, but want to go out of the laboratory, it takes time to implement it, how to stabilize the large-scale performance of graphene materials needs to be improved. Graphene, considered to be the most promising material in the future, is not only used in batteries, but also in other desalination, aerospace, flexible displays, hypersensitive sensing, biotechnology, composites, chips, etc.
