Anodic oxidation of metals leads to the formation of ordered nanoporous or nanotubular oxide layers that contribute to numerous existing and emerging applications. However, there are still numerous fundamental aspects of anodizing that have to be well understood and require deeper understanding. Anodization of metals is accompanied by the inevitable phenomenon of anion incorporation, which is discussed in detail in this review. Additionally, the influence of anion incorporation into anodic alumina and its impact on various properties is elaborated. The literature reports on the impact of the incorporated electrolyte anions on photoluminescence, galvanoluminescence and refractive index of anodic alumina are analyzed. Additionally, the influence of the type and amount of the incorporated anions on the chemical properties of anodic alumina, based on the literature data, was also shown to be important. The role of fluoride anions in d-electronic metal anodizing is shown to be important in the formation of nanostructured morphology. Additionally, the impact of incorporated anionic species, such as ruthenites, and their influence on anodic oxides formation, such as titania, reveals how the phenomenon of anion incorporation can be beneficial.

Sparking voltage is a vital parameter of the working electrolytes for aluminum electrolytic capacitors, which determines the operating voltage of the capacitors. However, the existing methods for measuring the sparking voltage suffer from low accuracy, bad reproducibility, high artificial error, etc. Here, we report a versatile approach for determining the sparking voltage of the electrolytes. By a linear fitting procedure, the voltage-time data acquired from the test experiments were transformed into a correlation coefficient-time curve. Because the abrupt correlation coefficient change due to the occurrence of sparking could be more readily identified in the correlation coefficient-time curve, the limit voltage of the electrolyte was accurately determined. Thus, this voltage was subtracted from the infrared drop in the solution to get the true sparking voltage of the electrolyte. This method prevented artificial errors arising from the direct observation or listening of sparking features, by which reliable and reproducible results can be gained by a computer program. This study provides an active support for the development of high-performance working electrolytes.
