【摘要】 通过共沉淀法制备了Mn₃O₄,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。更多还原

【Abstract】 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.更多还原
