Witryna10 kwi 2024 · The O 1s spectra can be fitted with two peaks (Figure S4D), correlated to the O Impurity (531.4 eV) and the O Lattice (529.4 eV). 38 The O Impurity is mainly caused by the active oxygen species O −, O 2−, or CO 3 2− of the impurity layer. The O Lattice is formed by the lattice oxygen (O 2−) of the TM–O bond (TM = Ni, Co, Mn). Witryna3 lis 2024 · The presence of impurities in the crystallization feed can influence these attributes, leading to inferior product quality and manufacturability. When impurities are not rejected during the crystallization and isolation processes, they contaminate the product, decreasing chemical purity.
