| 通过比较和分析制备的氧化锰电极材料的电化学测试结果，发现影响氧化锰电容性质的因素是多方面的，如材料的晶相、结晶性、比表面积和形貌等。通常，层状氧化锰和具有较大孔道尺寸的隧道型氧化锰的比电容较高，而具有较小孔道尺寸的隧道型氧化锰由于电解质离子难以进入隧道而具有很低的比电容。低结晶性氧化锰材料由于晶格松弛，离子嵌入/脱出反应容易进行，因而比高结晶性材料电容性质优异。大比表面积氧化锰材料往往可以提供更多的氧化还原反应活性位点而具有更高的比电容。氧化锰材料的形貌与其比表面积相关，而且会影响离子嵌入/脱出的路径，因而也是决定材料电容性质的重要因素之一。分级结构氧化锰材料在进行能量存储时具有很大优势，因为其兼具纳米尺寸构筑单元和亚微米尺寸堆积结构的优点。 |

| By analyzing the electrochemical test results of prepared manganese oxide electrode materials, it's discovered many factors attribute to the nature of the manganese oxide capacitance, like phase structure, crystallinity, specific surface area, morphology and so on. Typically, layered manganese oxide and tunnel-type manganese oxide with larger pore size obtain higher capacitance, the tunnel-type manganese oxide with a smaller pore size has a very low specific capacitance due to the electrolyte ions’ difficulty to enter the tunnel. Because of the lattice relaxation, in Low-crystallinity manganese oxide material, ion embedding/escaping reaction take place easily, and thus offer excellent high capacitance compared to the crystalline material. The manganese oxide of large surface area materials can often provide a more redox reactive sites, which has a higher specific capacitance. Manganese oxide material morphology are not only affected by its specific surface area, but also will affect the the ions embedding/escaping path, therefore it’s another one of the important factors that decide the material capacitance. The hierarchical structure of the manganese oxide material has a great advantage in energy storage, because it has both advantages of nanometer size building unit and sub-micron size stacking structure. |

Revised based on L1, ref. only: By comparison and analyses of the electrochemical test results of the prepared manganese oxide electrode materials, it is found that there are many factors affecting the capacitance properties of the manganese oxide, including crystal phases, crystallinity, specific surface area and morphology, etc. Usually, tunnel type manganese oxides with layered structure and those with relatively large pore sizes have higher specific capacitance, while those with relatively small pore sizes have relatively low specific capacitance due to difficulty of the electrolyte ions in entering into the tunnels. Due to lattice relaxation allowing ease of embedding/escaping reactions of ions, the low crystallinity manganese oxide exhibits superior capacitance performance compared to the crystalline material. The manganese oxide materials with large surface area usually can offer more redox active sites so that they have higher specific capacitance. The morphology of the manganese oxide material affects not only its specific surface area, but also the path of the ions embedding/escaping, therefore it is also one of the important factors determining the material’s capacitance. The hierarchical structured manganese oxide materials have a great advantage in energy storage due to their advantage features of nanometer size building unit and sub-micron size stacking structure. |
