Cover Picture: Electrochemical Fabrication of Coaxial Wavy-Channel NiIIIO(OH)/Ni Nanocomposites for High-Performance Supercapacitor Electrode Materials (Energy Technol. 8/2013)
Making Waves—Wavy-Channel Supercapacitor Electrodes: The cover image illustrates a NiIIIO(OH)/Ni coaxial nanocomposite with NiIIIO(OH) wrapped around a conductive Ni scaffold. The electrode could be prepared electrochemically with vertically oriented nanochannels and periodically corrugated channel walls. The Full Paper by Jian Lu and Yang Yang Li with colleagues at the City University of Hong Kong on page 478 demonstrated that this type of nanocomposite readily serves as a supercapacitor electrode with a remarkable specific capacitance of 2372 F g−1 at 1 A g−1 and excellent cyclability.
