New Graphene Quantum Batteries Break Through The Traditional Battery Limit

- Mar 15, 2017-

In recent years, the momentum of new energy is very fierce, whether it is related to its projects or products, casually can cause a topic of concern, new energy graphene quantum battery is a good example.

Today, China's new energy battery market with the rapid growth of the national economy and the rapid development of graphene industry Dongfeng, graphene battery market is developing steadily, and continue to attract foreign investment. Opportunities and challenges coexist, China's graphene battery companies can win this development opportunities? Market prospects are promising.

In addition to industrial applications, the current popularity of the battery is mainly used for mobile phones and electric vehicles in two ways. However, for a long time, the traditional lithium-ion batteries are energy-consuming, high cost, the use of conditions are limited, long charging time, short life time and other issues. Especially the use of time, I believe most people are more or less encountered a critical moment of the phone or the car suddenly no electricity embarrassment. With the development of the industrial age, the battery as a source of power in the world market share of the growing share of the traditional battery of these problems will become its own "criticism", need to be resolved. Technology and materials is the main breakthrough point, aware of the battery industry will be a huge market, the past few years, a large number of domestic and foreign enterprises and institutions have put into research, are hoping to find a perfect material development of new batteries, Limited.

At the same time, has been committed to the development of polycrystalline graphene found that the traditional lithium-ion batteries are used graphite anode material, in the case of similar negative performance, lithium-ion battery performance depends largely on the cathode material. Therefore, polycarbonate composites think of the use of new energy materials on the battery graphene. The experimental results show that by adding the graphene in the positive and negative materials of the lithium battery, one is as the conductive agent and the other is the lithium electrode as the negative electrode. At the same time, the battery internal resistance can be reduced, Greatly improve the battery cycle life and enhance the battery to withstand the role of high and low temperature performance.

Graphene battery has achieved a revolutionary success at the same time, polycarbonate meta-ferrite quantum battery research has also made brilliant research and development results. Recently, the chief scientist of polycarbonate composites, Professor Wang Dianlong of Harbin Institute of Technology in the field of graphene quantum battery made a major breakthrough. Through the experimental and theoretical calculations, they found that the self-developed nano-graphene / LiFePO4 battery in the aqueous solution with ultra-fast charge and discharge speed, 200C (3600/200 = 18 seconds) charge and discharge magnification, the capacity can maintain the theoretical capacity of 92% The This magnification is more than the fastest charge and discharge rate reported in 2006 by Professor MIT Ceder in Nature (56% capacity at 150 ° C), and found that the charge and discharge rate of organic electrolytes is about 10 times faster than that under the same conditions.
