论文2:Formation of CuMn Prussian Blue Analog Double-Shelled Nanoboxes Toward Long-Life Zn-ion Batteries 图3 Mn2p分峰拟合结果 这篇论文发表在了Angewan上,而且作者中也有不少大牛,说明整体工作是非常好的,我们这里只对XPS部分进行简单的分析。本文中,作者制备了一种CuMn普鲁士蓝类似物,为了表征材料中Mn的...
当放电到 1.5 V 时,该峰消失,证明了氧氧化还原反应具有良好的可逆活性。此外,非活性 Mn4+的存在导致阳离子氧化还原的减少,这可能导致氧化还原反应中氧的高参与。 参考文献 Li, Y., Hu, Y., Zhao, Y., & Zhang, J. (2020). In situ and operando X-ray photoelectron spectroscopy studies of electrode...

首先,掺杂元素在钠电池正极材料中的作用是多种多样的。它们可能用于提高材料的导电性、增加钠离子的存储容量或改善材料的结构稳定性。常见的掺杂元素包括铝(Al)、锰(Mn)、钴(Co)、镍(Ni)等。这些元素在化合物中的价态取决于其化学环境和配位数,并且可能受到电池充放电过程中的化学变化影响。

Presents a study which focused on the 2p3/2 X-ray photoelectron spectra (XPS) of Mn2+, Mn3+, and Mn4+ ions of some Mn-bearing oxides and oxyhydroxides, including manganite and synthetic birnessite. Information on experimental procedures used; What controls the formation rate of birnessite; ...

Calculated Mn(2p3/2) X-ray photoelectron spectra (XPS) of Mn2+, Mn3+, and Mn4+free ions are strikingly similar to Mn(2p3/2) spectra of Mn2+-, Mn3+-, and Mn4+-oxides and oxyhydroxides, indicating that these ions adopt high spin states in MnO, manganite, and birnessite. The Mn...
