The cobalt sulfide (CoS2) and nickel cobaltite (NiCo2O4) nanostructures are individually prepared and layered one over the other in reverse order to explore their effects on energy storage applications. The physicochemical characterization is conducted using X-ray diffraction, Raman spectroscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy, and transmission electron microscopy. The water contact angle of these nanostructures is also measured to assess their affinity toward aqueous electrolytes. The electrochemical performance and the contribution from surface-limited to diffusion-limited charge storage are measured. Among all the prepared nanostructures, cobalt sulfide grown over nickel cobaltite (CS/NCO) exhibited the highest specific capacity of 508.6 mAh⸳g−1 at a specific current of 1 A⸳g−1 using three electrode system. The same electrode demonstrated the highest specific power of 115.1 W⸳kg−1 in combination with a specific energy of 226.4 Wh⸳kg−1. Moreover, asymmetric device was also fabricated that exhibited maximum specific capacity of 49.8 mAh⸳g−1 at the specific current of 1 A⸳g−1, and specific energy of 93.0 Wh⸳kg−1 at specific power of 774.8 W⸳kg−1. The specific capacity of the full cell is retained up to 78.9 % after 5000 cycles. The post-electrochemical evaluation of CS/NCO is performed and the outcomes suggested that fabricated CS/NCO‖AC has promising future in the energy storage applications. Additionally, It is proposed that reversing the growth order of nanostructures in a hybrid electrode material is a potential pathway to optimize its electrochemical performance for energy storage applications.
