Abstract
AbstractTi–Ni–Si glassy alloy supercapacitors, devices that store electric charge on their TiO2 surfaces that contain many nanometer‐sized cavities, display many advantages over other power‐source technologies. The use of de‐alloying and anodic oxidization methods has made possible the synthesis of a TiO2 surface accessible to electron trapping. Until recently, no studies have addressed the “dry” electric storage in light glassy alloys. Our device realizes AC electric storage from 193 to 453 K with a voltage variation from 10 to 150 V, and DC capacitance of ∼4.8 F (∼52.8 kF/cm3), on the basis of electric double layers, deep electronic trapping sites and Shottky barriers. Further gains could be attained with surface optimization.magnified image(© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
