Cu₂MoS₄ Nanotubes as a Cathode Material for Rechargeable Magnesium-ion Battery

Identification of efficient cathode materials represents a huge challenge for development of reversible Mg-ion batteries (MIBs). Herein, we report on the preparation of copper molybdenum sulfide (Cu₂MoS₄) in a novel microstructure, namely nanotube with the square-cross-section, and its use as a cathode material for Mg-ion battery. The Cu₂MoS₄ nanotube was prepared via a one-pot hydrothermal method using Cu₂O nanocubes as a sacrificial template. The Cu₂MoS₄ nanotube belongs to the top-tier MIBs cathode materials that shows a remarkable specific capacity of 390.5 mAh g⁻¹.
