Nanotek Instruments Company of Ohio, USA, has developed a new battery that uses the characteristics of lithium ions to shuttle rapidly and massively between the graphene surface and electrodes. The new battery reduces charging times from hours to less than a minute. Analysts believe that the industrialization of one-minute fast-charging graphene batteries in the future will bring about changes in the battery industry, thereby also promoting innovation in the new energy vehicle industry.
The success of the new graphene battery experimental stage will undoubtedly become a new development point for the battery industry. Battery technology is the biggest threshold for the vigorous promotion and development of electric vehicles, and the current battery industry is at a stage where the development of lead-acid batteries and traditional lithium batteries has encountered bottlenecks. After the successful development of graphene energy storage equipment, if it can be mass-produced, It will bring new changes to the battery industry and even the electric vehicle industry.
Due to its unique properties, graphene is called a "miracle material", and scientists even predict that it will "completely change the 21st century." Professor Colin Bailey, Vice-Chancellor of the University of Manchester, said: "Graphene has the potential to revolutionize a huge number of applications, from smartphones and ultra-fast broadband to drug delivery and computer chips."
Recently, the University of California, Los Angeles, USA Researchers at the branch have developed a graphene-based micro supercapacitor. The capacitor is not only compact in appearance, but also charges 1,000 times faster than ordinary batteries. It can charge mobile phones and even cars in a few seconds, and can also be used to create volumetric batteries. smaller devices.
The breakthrough in micro-graphene supercapacitor technology can be said to have brought revolutionary development to batteries. At present, the main method of manufacturing microcapacitors is lithography technology, which requires a lot of manpower and cost, hindering the commercial application of the product. Now, more than 100 tiny graphene supercapacitors can be manufactured on a disc using cheap materials using a common DVD recorder or even at home in 30 minutes.
Having seen the application prospects of graphene, many countries have established graphene-related technology research and development centers, trying to commercialize graphene, and then obtain potential application patents in industry, technology and electronics-related fields. The European Commission has designated graphene as a "future emerging flagship technology project" and established a special research and development plan, allocating 1 billion euros in funding over the next 10 years. The British government has also invested in the establishment of the National Graphene Institute (NGI) in an effort to bring this material from the laboratory to the production line and market in the next few decades.
China also has unique advantages in graphene research. From a production perspective, graphite, which is a raw material for graphene production, has abundant energy storage and is cheap in my country. In addition, mass production and large-scale production are the main factors hindering the large-scale commercialization of graphene. The first 15-inch single-layer graphene in China was successfully manufactured using chemical vapor deposition method, and the graphene transparent electrode was successfully applied to the resistive touch screen to prepare a 7-inch graphene touch screen.
Researchers from the Chongqing Institute of Green Intelligent Technology, Chinese Academy of Sciences are demonstrating the super light transmittance and flexibility of single-layer graphene products.
Because graphene has unimaginable electrical conductivity, the graphene battery concept has become a life-saving straw to break through the bottleneck of current battery technology. In particular, any technological breakthrough in the domestic electric vehicle industry is linked to graphene batteries.
With the continuous deepening of research, the continuous overcoming of technical problems, and the continuous broadening of application scope, I believe that the era of graphene devices is not far away, and now we can also look forward to this "miraculous material of the 21st century" "What a surprise it will bring.
