Medium-entropy is a material design concept that has emerged in recent years.The medium-entropy materials possess unique properties.Medium-entropy molybdate (MnCoNiZn)MoO4 was synthesized by a facile solid-state reaction method.The microstructure,crystallinity,and elemental composition were characterized and analyzed by scanning transmission electron microscopy,polycrystalline powder X-ray diffractometer and X-ray photoelectron spectroscopy.The electrochemical performances of (MnCoNiZn)MoO4 as supercapacitor electrodes were investigated.At a current density of 1A/g,the specific capacitance of (MnCoNiZn)MoO4 electrode was 407F/g.When the current density increased to 15A/g,the specific capacitance of the electrode was 321F/g.After undergoing 10000 charge-discharge cycles,(MnCoNiZn)MoO4 retained 73.4% of its initial specific capacitance,thereby proving an impressively high capacitance retention rate.
