AB - Metal sulfides with high theoretical capacities have gradually gained attention as preferable anode materials for sodium-ion batteries. Tetragonal Cu3SbS4/rGO was synthesized by solvent thermal and ball milling and evaluated for the first time as lithium/sodium/potassium-ion battery anode material via constant current charge/discharge, rate charge/discharge, cyclic voltammetry, and electrochemical impedance spectroscopy. Ex-situ XRD revealed the lithium/sodium/potassium-ion mechanisms of the Cu3SbS4 anode, indicating that its capacity was mainly provided by the alloying reaction and conversion reaction. Due to high electrical conductivity of rGO, the Cu3SbS4/rGO electrode exhibited lower charge transfer resistance and more stable structure during charge/discharge process, reversible capacity and cycle performance of the Cu3SbS4/rGO were significantly improved compared with pristine Cu3SbS4. Therefore, the Cu3SbS4/rGO showed a discharge capacity of 283.9 mAh g−1 after 500 cycles at 1 A g−1 in lithium-ion batteries, a discharge capacity of 243.4 mAh g−1 after 300 cycles at 1 A g−1 in potassium-ion batteries and a discharge capacity of 193.0 mAh g−1 at 9 A g−1 in sodium-ion batteries. The results showed that Sb-based bimetallic sulfide have a certain development prospect as the anodes for lithium/sodium/potassium-ion batteries.Graphical abstractEx-situ XRD patterns and discharge/charge curves of the electrodes in initial cycle for LIBs/SIBs/PIBs[graphic not available: see fulltext]
