摘要

MoS2被认为是钠离子电池（sib）的阳极，其理论存储容量为670 mAh g−1。然而，它的不足降低了循环稳定性和容量保持。因此，本工作采用水热结合高温处理制备MoS2@C纳米片来改善这些问题。研究结果表明，MoS2@C电极在2.0 a g−1下，在第150次循环时获得227 mAh g−1的容量。

Optimized preparation of MoS2/C nanosheets for enhanced sodium-ion battery anode

MoS₂ has regarded as the anode for sodium-ion batteries (SIBs) with a theoretical storage capacity of 670 mAh g⁻¹. Nonetheless, its deficiencies reduce the cycle stability and capacity retention. Therefore, this work uses hydrothermal combined with high-temperature treatment to prepare MoS₂@C nanosheets to improve these problems. The study results demonstrate that the MoS₂@C electrode obtains a capacity of 227 mAh g⁻¹ at the 150th cycle at 2.0 A g⁻¹.
