Co/Ni-MOF-74-derived CoNi2S4 nanoparticles embedded in porous carbon as a high performance anode material for sodium ion batteries

In this study, Co/Ni-MOF-74-derived CoNi₂S₄ nanoparticles embedded in porous carbon (CoNi₂S₄@C) were successfully prepared using Co/Ni-MOF-74 as precursor. And, CoNi₂S₄@C exhibits excellent electrochemical performance as an anode material for sodium ion batteries.
