| 二次电池由于具循环寿命长，成本低廉，绿色环保等优点受到科研工作者的广泛关注，而电极材料对整个电池系统的性能起着至关重要的作用。二硒化钼由于具有独特的层状结构、电导率高、带隙较窄等特点，被认为是储能领域的明日之星。然而，金属硒化物在循环过程中体积变化严重，导致动力学和电化学稳定性较差，限制了其在二次电池中的进一步实际应用。因此，通过调整合成方法、与碳质材料复合、设计独特的结构等手段来缓解金属硒化物电极的稳定问题。本文综述了二硒化钼材料的制备工艺、复合改性方法及其在二次电池中应用现状，最后对该材料在二次电池中所面临的挑战和应用前景进行了总结。 |
| 英文摘要: |
| Secondary charge batteries (SCBs) have captured numerous attentions, owing to their long cycle life, low cost and environmental protection, and the electrode materials serve vital roles on the properties of whole battery system. Currently, MoSe2 is regarded as rising star of transition metal dichalcogenides, displaying unique layered structure, high electronic conductivity, as well as narrow energy band. However, as conversion/alloying based electrode materials, metal selenides suffer from a severe volume change during cycling, thus leading to kinetic problems and poor electrochemical stability, which restrain their further application in SCBs. Therefore, modification strategies such as adjust the synthesis method, coupling with carbonaceous material, designing unique structure etc. have been adopted to alleviate the volume change issue of metal selenides electrodes. In this article, the research summarizes the MoSe2 as electrodes for SCBs contains the synthesis methods, modification methods for performance improvement. Finally, a conclusion with the challenges and outlook of MoSe2 in the field of SCBs is also presented. |
