MoWS2 Nanosheet Composite with MXene as Lithium-Sulfur Battery Cathode Material

Due to their superior theoretical specific capacity and energy density, lithium-sulfur (L‒S) batteries are gaining popularity in order achieve the growing terms for more power generation. However, drawbacks such as low electrical conductivity of active ingredient sulfur, severe volume expansion shuttle effect polysulfides, rapidly decaying battery capacity, short life have hampered development. A MoWS2@MXene@CNT composite material is used main cathode L-S this study. MoWS2 can improve electrochemical reaction rate by accelerating polysulfide conversion, whereas MXene suppress electrode expansion. Furthermore, addition carbon nanotubes (CNT) with high improves reaction. Therefore, composites good versatility materials enhance behavior batteries.
