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

Abstract

On account of its low cost, non‐toxicity and high theoretical capacity, ZnS has been considered as one of the most potential anode materials for the following generation lithium‐ion batteries. However, the shortcomings that ZnS shows, such as low conductivity and large volume changes, make its wide application difficult. Herein, we combined ZnS with metal‐organic framework material (ZIF‐8) to form a carbon layer on the surface of nitrogen‐doped zinc sulfide, and obtained a new material ZnS@NC with a specific surface area of 191 m2 g−1. The results show that the reversible specific capacity of the composite is 853 mAh g−1 when the current is 500 mAg−1, which is caused by the increase of specific capacity with nitrogen doping and the effective adjustment of the volume of the carbon layer coated on the periphery of the ZnS particles during charging and discharging process. Promisingly, the performance of ZnS@NC composite is far superior to that of the bare ZnS.

MOF-Derived ZnS Nanodots/Ti3C2Tx MXene Hybrids Boosting Superior Lithium Storage Performance

“…For pure ZnS, the lithiation capacity decreases sharply to 190 mAh g −1 after 20 cycles. The rapid capacity fading may be ascribed to the pulverization of ZnS due to its large volume change during charge-discharge [58]. In contrast, the ZnSMX64 exhibits the best cycle stability and a high capacity of 650.6 mAh g −1 is remained after 100 cycles.…”

“…As a contemporary energy storage rechargeable battery equipment, LIBs have been diffused utilized in energy storage power systems (such as solar power plants), electric vehicles, military equipment, aerospace and other fields. [1][2][3] Metal oxide anode materials (such as ZnO, SnO 2 , CuO, etc.) can provide superior specific capacity through conversion reaction to achieve efficient energy storage, which makes up for the imperative bottleneck problem of low specific capacity of existing commercial graphite anodes.…”

Preparation of ZnS@N-doped-carbon composites via a ZnS-amine precursor vacuum pyrolysis route

“…5,6,9,10 In general, the ZnS/C nanocomposites can be prepared by compositing ZnS with a pre-prepared carbon source such as graphite, 11 graphite oxide, [12][13][14] reduced graphene oxide 15 and carbon nanotubes. [16][17][18] Another method is to carbonize a specic precursor such as a metal organic framework (MOF) [19][20][21][22] and polymerize with embedded nano ZnS. 9,[22][23][24] Although much progress has been made, there are still some limitations in the preparation of ZnS/ C nanocomposites, such as harsh experimental conditions and laborious synthetic procedures.…”
