With the development of electronic equipment and new energy vehicles, batteries have become an indispensable product in life. Battery power consumption and lifespan have become urgent problems today. Graphene, as a "black gold" material with wide applications and excellent performance, has high hopes from the scientific community, and domestic and foreign researchers have never stopped researching it.
Recently, the research group of the University of Electronic Science and Technology of China has made a breakthrough in graphene supercapacitor technology. This technology uses simple preparation methods to effectively reduce production costs and promote industrial development. This good news has stimulated the research enthusiasm of scientific researchers and also provided new graphene research directions.
How does the University of Electronic Science and Technology of China research team use graphene to improve the cost performance of supercapacitors?
Members of the research team used an electric field-assisted method to assemble graphene oxide sheets to prepare a 3D graphene network. As expected, the supercapacitor based on the 3D graphene network achieved high specific capacitance and good rate performance, significantly improved due to the large electrolyte accessible surface area and high conductivity.
What is the connection between the technological breakthrough of supercapacitors and batteries?
Supercapacitor is an electrochemical physical component that does not have chemical reactions of its own. Supercapacitors store energy by injecting electrolytes. Under the action of electrodes, the surface charge of the electrolytes absorbs surrounding heterogeneous ions and adheres to the electrode surface to form a double charge layer. It uses a special electrode structure to produce a huge capacitance.
The research technology of the University of Electronic Science and Technology of China has improved the energy storage problem of supercapacitors to a certain extent, reduced battery power consumption and extended service life. Looking to the future, with the advancement of science and technology, the application of graphene in the battery field will become more and more in-depth and will be widely used in the battery industry.
