The use of such parameters makes the search for ions with desired properties a lot easier. First of all, such descriptors can be relevant in the field of catalysis, especially for catalyst surface composition control and in surface chemistry, for example, when searching for ions with the highest adsorption for a given material to solve the problem of heavy metal binding by different sorbents. An example of possible practical application of the descriptors was clearly demonstrated by aqueous electrolytes for batteries. Li + was used as the cation, the anion parameters were estimated by the previously obtained expressions, the task was to select an anion the use of which would minimize the degree of water coverage of the electrode surface.
