Abstract:

Constructing hybrid heterostructures of transition-metal dichalcogenides is an effective strategy to enhance their electrochemical performance and stability as anode materials in lithium-ion batteries. In this work, a facile in situ strategy was developed to engineer lattice-mismatched MoS2-ZnS together with C into hierarchical nanostructures. The three-dimensional architecture was constructed using few-layer MoS2 nanosheets as the building block, and ZnS and C coexisted among the MoS2 nanosheets with a mesoporous structure. By the synergy effect of integrated interfaces and hierarchical configuration, as-formed heterostructures exhibit increased conductivity, enhanced Car transfer efficiency, and retarded volume expansion during the electrochemical process. All of these contribute to the greatly increased lithium storage capability and well-preserved stability. Impressively, as-obtained materials exhibit a high lithium storage capacity of 961.9 mA g(-1) at 100 mA g(-1) after 100 cycles (about 3.1 times higher than pristine MoS2 after 35 cycles), good rate retention, and superior cycling stability with 9.5% decay. Therefore, the proposed strategy provides a favorable direction for developing high-activity and low-cost electrode materials with potential applications in electrochemical fields.
