Plate‐like ZnS/C composite with the uniform combination of ZnS and carbon is obtained by pyrolyzing the metal–organic framework precursors which consist of Zn 2+ and sulfur‐containing organic ligand and is used for high‐performance anode materials in Li‐ion batteries. The carbon in the composite synthesized cannot only improve the conductivity, but also efficiently buffer the large volume change of ZnS during the charge/discharge process, meanwhile the ZnS in composite mainly provides the specific capacity. Typically, after 80 cycles, the reversible capacity of the composite can maintain at 624 mAh g −1 under 0.3 A g −1 current density.
