摘要：
Metal sulfide represents one of the most promising anode materials for sodium-ion batteries (SIBs). In this study, we report the design and synthesis of nitrogen-doped carbon coating mesoporous ZnS nanospheres (m-ZnS NSs@NC) via a simple hydrothermal reaction, followed by a carbonization process. Systematic electrochemical studies demonstrate the as-developed m-ZnS NSs@NC exhibits good cycling stability and high rate capability as anode materials of SIBs. The excellent electrochemical performance can be attributed to the synergistic effect of the special mesoporous structure of ZnS nanospheres and the polydopamine-derived N-doped carbon coating.
