Synergy unleashed: NiMoO4/WO3/NF nanoflowers elevate for supercapacitor performance

Nickel molybdate oxide (NiMoO4) and tungsten trioxide (WO3) are becoming progressively more commonly suitable as electrode materials for supercapacitors owing to their chemical stability, peculiar layered structure, and significant capacitance. Unfortunately, most of the published works based on NiMoO4 and WO3-based electrodes show lower electrochemical performance due to their poor conductivity and fast capacitance fading. Here, we reveal methods to build hierarchical nanoflowers formed from NiMoO4/WO3/NF for the very first time, which enhances the supercapacitor's electrochemical performance. The potential benefits of the NiMoO4/WO3/ NF suitable to be a binder-free electrode material for supercapacitor utilization seem very fascinating. In com-parison to the pristine NiMoO4/NF (263.75 F g-1) and WO3/NF (197.91 F g-1) materials, the NiMoO4/WO3/NF nanocomposite exhibits remarkable precise capacitance of 429.46 F g-1 at 1 A g-1, exceptional reliability alongside over 89.9 % the capacitance preservation after 10000 cycles, and low charge transfer resistance. NiMoO4/WO3/NF nanocomposite exhibits outstanding electrochemical performance and is mainly allocated to the beneficial synergistic effect of its peculiar structure, which may offer additional routes for the movement of electrons and maximize the efficiency of the utilization of the electrode material. The findings imply that these kinds of nanocomposite electrodes have a lot of promise for application in energy storage.

Automated summary

Nickel molybdate oxide and tungsten trioxide have potential as electrode materials for supercapacitors, but their poor conductivity and fast capacitance fading limit their performance. By building a hierarchical nanoflower structure, the electrochemical performance of the supercapacitor is enhanced.
