Nanosized Ni-3(Fe(CN)(6))(2)(H2O) Was prepared by a simple co-precipitation method. The electrochemical properties of the sample as the electrode material for supercapacitor were Studied by cyclic voltammetry (CV), constant charge/discharge tests and electrochemical impedance spectroscopy (EIS). A specific capacitance or 574.7 Fg (1) was obtained at the current density of 0.2 A g(-1) in the potential range from 0.3 V to 0.6 V in 1 M KNO3 electrolyte. Approximately 87.46% of specific discharge capacitance was remained at the current density of 1.4 A g (1) after 1000 cycles. (c) 2008 Published by Elsevier B.V.
