Abstract: Electrode materials based on NiCo2O4 associated with CoNi-LDH are interesting in the area of energy storage. In this work, the obtaining of CoNi-LDH from ZIF-67, according to XRD data, was successful. The association of NiCo2O4 and CoNi-LDH proved to be efficient, where the NiCo2O4@CoNi-LDH material presented superior electrochemical results when compared to its precursors individually. Furthermore, are observed for NiCo2O4@CoNi-LDH specific capacitance of 586.96 F g-1 and coexistence of charge storage mechanisms controlled by diffusion and capacitive processes, emphasizing the excellent potential of this material in the composition of positive electrodes of energy storage devices.
