Theoretical Specific Capacity and Metal Ion Diffusion Pathway of NiMoO₄ Microspheres for Hybrid Supercapacitors.

ABSTRACT: Transition metal molybdates are one of the most prominent materials for energy storage devices. The present investigation establishes a strong correlation between the structure and electrochemical performance of NiMoO₄ through Density Functional Theory (DFT). Initially, the NiMoO₄ microspheres are directly deposited on nickel foam using a hydrothermal method by tuning experimental parameters. When employed as electrode materials, the NiMoO₄ microspheres deliver a specific capacity of 168.9 mAh g^-1 at 1 A g^-1. In addition, the material retains 80% capacity over 7000 charge-discharge cycles with 98.3% coulombic efficiency, implying its excellent stability. DFT calculations are used to determine specific capacity and potassium ion diffusi
