Abstract

Porous MoO₃ films with an ultra-short relaxation time used for supercapacitors have been prepared in acid peroxo-polymolybdate solution by electrodepositing on Ni foam directly in this study. Electrochemical measurements indicate that, the films behave an ideal supercapacitor characteristic in Na₂SO₄ electrolyte. The electrochemical impedance spectroscopy results demonstrate that, the films have a very low relaxation time constant (1 ms), which reveals a potential application prospect in filtering voltage ripple.
