Graphene battery
Graphene battery, a new energy battery developed by utilizing the characteristics of rapid ion transport of lithium ions between the graphene surface and the electrode.
The success of the experimental phase of the new graphene battery will undoubtedly become a new development point of the battery industry. Battery technology is the biggest threshold for the promotion and development of electric vehicles. The battery industry is in the stage of bottlenecks in the development of lead-acid batteries and traditional lithium batteries. After the successful development of graphene energy storage equipment, if it can be mass-produced, it will be The battery industry and even the electric vehicle industry have brought about new changes.
Because of its unique characteristics, graphene is called "magic material", and scientists even predict that it will "completely change the 21st century." Professor Colin Bailey, vice president of the University of Manchester, said: "Graphite has the potential to revolutionize a wide range of applications, from smartphones and ultra-high-speed broadband to drug delivery and computer chips."
Recently, researchers at the University of California, Los Angeles, developed a graphene-based micro-supercapacitor that is not only small in size, but also 1000 times faster than ordinary batteries, and can charge mobile phones and even cars in seconds. It can also be used to make smaller devices.
The breakthrough of micro graphene supercapacitor technology can be said to bring revolutionary development to the battery. The main method of manufacturing microcapacitors is lithography, which requires a lot of manpower and cost, and hinders the commercial application of the products. And only need a common DVD burner, even at home, using cheap materials for 30 minutes to make more than 100 micro graphene super capacitors on a single disc.
It is the application prospect of graphene. Many countries have established graphene-related technology research and development centers, trying to use graphene commercialization, and then obtaining potential application patents in industrial, technical and electronic related fields. The European Commission has set up a special R&D plan as a “new future flagship technology project” and will allocate 1 billion euros in the next 10 years. The UK government has also invested in the National Graphene Research Institute (NGI) in an effort to bring this material from the laboratory to the production line and market in the coming decades.
China also has unique advantages in graphene research. From a production perspective,
As a raw material for graphene production, graphite is abundant in energy storage in China and has low price. In addition, mass production and large-scale production are the most important factors hindering the large-scale commercial use of graphene. The first 15-inch single-layer graphene was successfully fabricated by chemical vapor deposition, and the graphene transparent electrode was successfully applied to a resistive touch screen to prepare a 7-inch graphene touch screen.
Researchers at the Chongqing Institute of Green and Intelligent Technology of the Chinese Academy of Sciences are demonstrating the superior light transmission and flexibility of single-layer graphene products.
Because graphene has an unimaginable conductivity, the graphene battery concept has become a life-saving straw that breaks through the bottleneck of battery technology. Especially in the domestic electric vehicle industry, all technical breakthroughs are linked to graphene batteries.
With the deepening of research, the technical problems have been successively overcome, and the scope of application has been continuously expanded. It is believed that the era of graphene devices is not far away, and we can also expect some surprises from this "21st century magic material".
"The graphene battery will be reformed: charging 1000 kilometers for 10 minutes"
Report: Spain's Grapheno Company (a company that produces graphene on an industrial scale) has collaborated with the University of Corvado in Spain to develop the first graphene polymer material. The battery, which has three times the storage capacity of the best products in the market, can travel up to 1000 kilometers with an electric vehicle that provides electricity, and its charging time is less than 8 minutes. Although this battery has various excellent properties, its cost is not high. According to the person in charge of Graphenano, the cost of this battery will be 77% lower than that of lithium batteries, which is completely within the consumer's tolerance. In addition, in the field of automotive fuel cells, graphene is expected to bring revolutionary progress.
