Controllable Synthesis of Two-Dimensional Molybdenum Disulfide (MoS₂ ) for Energy-Storage Applications

Lamellar molybdenum disulfide (MoS₂ ) has attracted a wide range of research interests in recent years because of its two-dimensional layered structure, ultrathin thickness, large interlayer distance, adjustable band gap, and capability to form different crystal structures. These special characteristics and high anisotropy have made MoS₂ widely applicable in energy storage and harvesting. In this Minireview, a systematic and comprehensive introduction to MoS₂ , as well as its composites, is presented. It is aimed to summarize the various synthetic methods of MoS₂ -based composites and their application in energy-storage devices (lithium-ion batteries, sodium-ion batteries, lithium-sulfur batteries, and supercapacitors) in detail. Based on recent studies, this Minireview provides important and comprehensive guidelines for further study and development efforts in the MoS₂ in energy-storage field.
