Abstract
Nanomaterials have special properties, and have important applications in energy storage and many other devices. For energy storage, supercapacitors have attracted great interest and development. Supercapacitor have found a lot of applications in electric cars and other equipment. Different materials have been proposed and used for supercapacitors. In this presentation, high performance supercapacitors based on nanoscale Ni-based materials, which show very high specific capacitance and energy density, are focused. The energy storage performance of such materials and devices are examined and the very high energy storage ability is discussed. Energy storage performance, microstructure, morphology and surface area are found strongly related to Ni and Co oxide structures and morphologies, and the incorporation of some other active materials also enhance performance. 3D core-shell structures contributing to energy storage is presented and discussed. Charged small full supercapacitors prototype will be shown to light up bulb and turn fans for a long time in this presentation.
