Electrochemical intercalations of divalent ions inside Ni/Zn co-doped cobalt sulfide nanoparticle decorated carbon spheres with superior capacity

Different kinds of CoS₂ nanoparticles incorporated into carbon spheres synthesized by hydrothermal method were employed as cathode materials in MIBs and MLIBs to achieve the capacities of 158 mA h g⁻¹ and 667 mA h g⁻¹, respectively.
