Battery special graphiteApplication

With the gradual breakthrough of mass production and scale problems, the pace of industrial application of graphene is accelerating. Based on the research and development achievements of China's existing technology, the first batch of commercial applications may be in the fields of mobile electronic equipment, aerospace and new energy batteries.

Flexible screens have attracted much attention at the Consumer Electronics Show and become the development trend of mobile device displays in the future. The future market for flexible displays is huge, and the future of graphene as a basic material is also promising.

On the other hand, the commercialization of graphene for new energy batteries is an important area. The college can successfully develop flexible photovoltaic panels with Chinese graphene nanolayers on the surface, which can greatly improve and reduce the cost of manufacturing transparent deformable solar cells, and can be used for small system applications in digital technology equipment such as night vision goggles and cameras. In addition, the successful research and development of graphene batteries has also solved the problems of insufficient battery capacity and long charging time for new energy vehicles, and greatly accelerated the development of the new energy battery industry. This series of research and development results paved the way for the application of graphene in the new energy battery management industry.

Graphene for battery has high conductivity, high strength and ultra-thin properties, and has been widely used in aerospace and military fields. A graphene sensor used in the aerospace field can detect trace elements in the upper atmosphere of the earth and structural defects on spacecraft. Graphene will also play a more important role in potentially developing applications such as volume materials for ultraltweight aircraft.

From a microscopic point of view, the charging and discharging process of a battery is actually a process in which cations are "embedded" and "separated" in the electrode. Thus, the process proceeds faster if there are more pores in the electrode material. From a macro point of view, the faster the charge and discharge speed of the battery.

The microeconomic structure of graphene for batteries is a network structure that can be composed of carbon atoms. Because it is very thin (only one layer of atomic thickness), the movement of cations is very limited. At the same time, due to the mesh structure, the electrode material made of graphene also has enough holes.

From the development of this problem, graphene is undoubtedly a very ideal electrode material.

The technological breakthrough of micro-graphene capacitors can be said to have changed the development of batteries. The main method of manufacturing microcapacitors is photolithography, which requires a lot of labor and cost, and hinders the commercial application of the product. It only takes an ordinary DVD burner, even at home, to make more than 100 tiny graphene capacitors on a single disc in 30 minutes using cheap materials.
