摘　　要：以钼酸钠为钼源,硫代乙酰胺为硫源,通过水热法制备了由纳米片组成的三维花状结构的二硫化钼,并利用XRD、SEM、TEM对产物的微观结构和形貌进行了表征;同时用该材料制备了锂离子电池,最高放电比容量达1342.8mA.h/g,二硫化钼独特的结构使其成为锂离子电池负极材料较好的选择。Three-dimensional flowers-like molybdenum disulfide composed of nanoflakes were synthesized by hydro- thermal process using sodium molybdate and thioaeetamide as reactants. The morphology and microstructure of the prod- ucts have been characterized by XRD, SEM, TEM, HRTEM. Besides, we prepare Li-ionic battery with the obatined prod- ucts, Which exhibited the highest specific capacity of - 1342.8mAhg-1. The unique structure of molybdenum disulfide made it became the most promising alternative cathode material for lithium ionic batteries.
