The research team at the University of Florida has succeeded in developing a new battery technology that greatly improves the charging time and the number of times of use of the conventional battery. With the technology developed by the research team, it is possible to charge batteries of smartphones in a few seconds and to develop batteries with durability of 30,000 times or more.

The research team at the University of Central Florida Nanoscience Technology Center in the US,Electric double layerWe have been researching the technology to make it possible to use the "electric double layer capacitor" which uses the physical phenomenon called "electric double layer capacitor" by using the physical phenomenon like a general battery for many years. There was a problem that the capacitor itself became too large to use the electricity storage amount of the electric double layer capacitor equal to the lithium ion battery.


However, the research team devised a technology to coat the poles of the battery with two-dimensional nanomaterial typified by graphene. Using this technology, we developed an electric double layer capacitor using wires coated with two-dimensional nanomaterials. As a result, high-speed movement of electrons became possible, high-speed charging was possible, electricity with high energy and energy density The double layer capacitor was completed.

With the technology developed by the research team, it will be able to charge more than 30,000 times, and if it is a smartphone battery, it will be possible to develop batteries that can fully charge in a few seconds.

Associate professor Eric Young who led the research said, "How to combine two-dimensional nanomaterials into existing systems has been a long-standing problem, but if we use chemical synthesis method we developed, existing materials and two-dimensional We can properly combine nanomaterials of various types "," it is revealed that breakthrough of experiment was in chemical synthesis. "

Young Associate Professor Yong said, "In the case of small electronic devices, the technology we developed greatly surpasses existing technologies in terms of energy density, power density, stability", but at the moment writing the article So it is a stage where we succeeded in developing the demonstration model, and it seems that it will take a long time to commercialize.

The research team is applying for the patents on battery technology invented this time.
