The present invention relates to a method of preparing a NiCo 2 O 4 nanostructure having a mesoporous structure. When the NiCo 2 O 4 nanostructure having a mesoporous structure prepared by the above method is used as an electrode active material, , Respectively. The storage capacity after 1,500 times of use was only 4.7% lower than that of the initial capacity, thus exhibiting excellent cyclic stability. In particular, the composite is a very simple and efficient method . |
