摘　　要：二硫化钼(MoS2)材料作为下一代可充镁电池的正极材料,目前正在成为能源领域的一个研究热点。为了降低可充镁电池的制造成本,提高商品化MoS2材料的性能,采用超声处理方法对商品化MoS2材料进行了超声振荡处理,然后将其作为正极材料与纯镁片组装成可充镁电池进行了充放电性能测试。实验结果表明,与未经过处理的商品化MoS2材料相比,超声处理可以有效地改善商品化MoS2材料片层结构单元的分散性,能够为镁离子的嵌入和嵌出提供了更多的扩散通道,从而提高了商品化MoS2电极材料的充放电比容量和循环稳定性。MoS2 as cathode materials of the next generation rechargeable battery is becoming a research focus in the field of energy industry. In order to reduce the manufacturing cost of rechargeable magnesium batteries and improve the electrochemical performance of commercial MoS2 materials, the commercial MoS2 materials were processed by an ultrasonic treatment and assembled into a rechargeable magnesium battery as the cathode material for charge-discharge testing. The testing results show that the ultrasonic treatment can effectively improve the dispersion of laminated structure units in commercial MoS2 cathode materials and provides more intercalation channels of Mg2＋ in commercial MoS2 materials. It is evident that the ultrasonic treatment of commercial MoS2 cathode materials can increase both the specific capacity of charge/discharge and the cyclic performance of rechargeable magnesium batteries.
