Synthesis of ZnS/C Composites by Metal‐Organic Framework as High‐Performance Lithium‐Ion Batteries

Abstract

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. Conflict of InterestThe authors declare no conflict of interest.

Zinc Sulfide Decorated on Nitrogen‐Doped Carbon Derived from Metal‐Organic Framework Composites for Highly Reversible Lithium‐Ion Battery Anode

“…Hence, low‐cost, non‐toxic and high theoretical capacity zinc sulfide has been studied as an alternative anode material. However, it still exists many defects, such as poor conductivity, weak stability, small specific surface area and so on . Urgently, it is vital to design and improve the performance of ZnS.…”
