A New, Friendlier Methodology to Determine the Average Manganese Valence in LixMn2O4 Spinels Using Atomic Absorption Spectrometry and Molecular Absorption Spectrophotometry
(Soc Brasileira Quimica, 2018-04-01)
An alternative, friendlier methodology for the determination of the average manganese valence (nu) of manganese oxides (mainly pure and doped spinels) is presented. This methodology is based on the facile determination of ...
Effect of x on the Electrochemical Performance of Two-Layered Cathode Materials xLi2MnO3–(1−x)LiNi0.5Mn0.5O2
(MDPI, 2022-06-29)
In our study, the cathodic material xLi2MnO3–(1−x)LiNi0.5Mn0.5O2 was synthesized by means of the co-precipitation technique. The effect of x (proportion of components Li2MnO3 and LiNi0.5Mn0.5O2) on the structural, ...
