The ability of an electrolyte to conduct ions is evaluated by its ionic conductivity. The ionic conductivity is defined in Eq. (1) [19], where μ i is the ion mobility of different ions, n i is the free-ion number, e is a unit charge, and z i is the charge valence. It can be concluded from Eq. (1) that the conductivity of electrolytes is mainly affected by μ i, z i, and n i.
