摘　　要：MoS_(2)是一种典型的具有类石墨烯结构的二维层状材料,高纯MoS_(2)的热分解温度可达800℃左右,表现出极好的热稳定性。选用超临界水体系制备MoS_(2),并对其微观形貌、热稳定性以及作为热电池正极材料的放电性能等方面进行分析。研究结果表明,通过超临界水体系可以制备出花瓣形貌的MoS_(2),并且1T-MoS_(2)组分可占据整个晶相的30.8%,作为热电池正极材料时,表现出优异的电化学性能。MoS_(2)is a typical two-dimensional layered material with grapheme-like structure,the ther‐mal decomposition of high-purity MoS_(2)can reach about 800℃,showing outstanding thermal stabil‐ity.The supercritical water system is used to synthesis MoS_(2),and its microstructure,thermal stability and discharge performance as a cathode material for thermal battery are analyzed.The results show that the flower-shaped MoS_(2)can be prepared by supercritical water system,and the 1T-MoS_(2)compo‐nent can occupy 30.8%of the total crystalline phase.When used as the cathode materials of thermal battery,MoS_(2)shows satisfied electrochemical performance.
