CV curves at different rates and CV comparison between Ni foam and Co-Mn composite oxide nanostructures/Ni foam. (a) CV curves at different scan rates recorded from Co-Mn composite oxide hierarchical structures/Ni foam electrode. (b) CV comparison of the treated Ni foam and Co-Mn composite oxide nanostructures/Ni foam at the scan rate of 20 mV s-1.
