K19.03 - Graphene/Carbon Nanotubes Hybrid for Energy Storage 
December 4, 2014   4:00pm - 4:30pm

One-dimensional carbon nanotubes and atomically thin two-dimensional graphene, as a brother in nanocarbon family, have themselves superior material properties such as high mechanical strength, high electrical conductivity, high surface area, and excellent chemical stability, which are certainly beneficial for energy storage. Nevertheless, when they are used for energy storage for instance, supercapacitor, battery, and hydrogen storage, their performance is still limited due to different processibilities. In spite of such different processibilities, the performance can still be maximized by appropriately forming carbon nanotube-graphene hybrid structures. The current sophistigated electronics industry and technology require often versatile types of devices for energy storage. I will demonstrate several examples of such hybrid structures and sometimes with other materials which could be useful for different purposes of energy storage devices.
