Summary: The rational construction of active materials with hierarchical structure is an effective strategy for achieving high electrochemical performance in supercapacitors. In this study, ultra-thin nickel hydroxide nanosheets were grown directly on the external surface of Ni3S2 nanorod arrays on nickel foam using a simple hydrothermal method to form Ni3S2/Ni(OH)2 hierarchical nanoarrays. The Ni3S2 nanorod arrays not only served as the main pathway for charge transport and supported the growth of active materials, but also participated in the electrochemical energy storage process. The external ultra-thin nickel hydroxide nanosheets increased the contact area with the electrolyte and enriched the electrochemical active sites. The Ni3S2/Ni(OH)2 composite showed excellent electrochemical performance due to its hierarchical structure, which increased the effective specific surface area of the electrode materials and induced a synergistic effect between the components.
