摘要
通过共沉淀法制备了Mn_3O_4,再通过多巴胺包覆烧结得到碳包覆的MnO@C,并将其用作锌离子电池正极材料。结果表明,组装电池在0.2 A/g下比容量达到282.9 mAh/g。在1 A/g下循环500次后,比容量为80.2 mAh/g。碳包裹MnO可为Mn基锌离子电池开发提供新思路。
Mn3O4 was prepared by co⁃precipitation method,which was then coated with dopamine and subjected to sintering process,generating carbon⁃coated MnO@C.It can be used as a cathode material for zinc⁃ion batteries.The test results show that the assembled battery with this material has a specific capacity of 282.9 mAh/g at 0.2 A/g.After 500 cycles at 1 A/g,the specific capacity is 80.2 mAh/g.It is concluded that MnO@C can provide new ideas for the development of Mn⁃based zinc ion batteries.
