摘要：

Present study reports the electrochemical behavior of BiNi0.6Mn0.4O3 nanostructures synthesized via citric acid and ethylene glycol assisted hydrothermal process at low temperature calcination of 400(o)C. Raman spectroscopy and Rietveld refinement have confirmed BiNi0.6Mn0.4O3 to crystallize in tetragonal phase with 2(1)c space group symmetry. X-ray photoelectron spectroscopic analysis showed the presence of 'B' cations, Ni and Mn in (+2) and (+4) oxidation states, respectively, which mainly contributed to faradaic reactions as observed in CV curves. The specific capacitance of BiNi0.6Mn0.4O3 electrodes has been found to be similar to 243 F g(-1) at the current density of 1 A g(-1) in a 6 M KOH aqueous solution. The nanostructured electrodes showed a cyclic stability of similar to 70% after 4000 charge-discharge cycles at the current density of 6 A g(-1) .
