NiMoO₄/MnCo₂O₄ for high-performance positive electrodes of supercapacitors

Abstract

Abstract To discover more effective energy storage materials, it is crucial to investigate the impact of composite properties. The composite material NiMoO 4 /MnCo 2 O 4 was synthesized on a nickel foam substrate through hydrothermal and annealing methods. Physical and electrochemical performance tests were subsequently performed on the product. The X-ray diffraction analysis revealed a blend of NiMoO 4 and MnCo 2 O 4 peaks. The microscopic morphology of the composites yielded both nanosheet arrays and nanoflowers. Furthermore, the EDS patterns demonstrated inconsistent elemental distributions, which confirm a composite material nature. The material exhibits promising electrochemical properties, offering a viable solution for incorporating composites into the anode of supercapacitors.
