Abstract
MoS3 nanoparticles as well as MoS3 on graphene and multiwalled carbon nanotubes were synthesized by a solvothermal method and the prepared samples were employed as cathode material in zinc-ion batteries. With distinct advantages like low price, high safety, no environmental pollution, and high power, these batteries have promising properties for future generation battery systems. The microstructure and elec-trochemical properties of the prepared composite cathodes were investigated by XRD, TG, and XPS. The MoS3/MWCNTs have a discharge specific capacity of 368 mAh g-1 at the current density of 500 mA g(-1) and stable cycling performance, and the discharge specific capacity of MoS3/MWCNTs can still reach 321 mAh g-1 at the current density of 1 A g(-1). Making use of the outstanding mechanical, electrochemical and electronic properties of MWCNTs, the coated composite of MoS3 nanoparticles on MWCNTs can sig-nificantly improve the electrical conductivity of the materials, and enhance the charge-discharge capacity and high rate characteristics of MoS3 as aqueous zinc-ion cathode material.
