The North Carolina State University research team has presented the unusual nanoflower structure that might in future result in more efficient batteries and solar cells. In fact, the flower-like shape is ideal for improving energy storage cells: the more layers you work with, the greater is the surface area and capacity to hold the energy. The new technique is based on creating multi-layered nanostructures as a result of heating powdered germanium sulfide (GeS) until it vaporizes and then turns into a layered sheet 20 to 30 nanometers thin, and up to 100 micrometers long. GeS is good at absorbing solar energy and converting it to power fit to be used, furthermore the material is relatively cheap and non-toxic. Dr. Linyou Cao, an assistant professor of materials science and engineering at NC State reports, that the nanoflower structure could be used for increasing the capacity both of lithium-ion batteries and supercapacitors.
