Introduction

Electrical mobility determines a set of physical chemical properties that reflect an inherent ability of charged particles, such as electrons, protons, and generally ions, to move through certain condensed medium in response to the action of external electric fields. Application of an external electric field allows to spatially separate ions in electrolytes (see electrochemical devices) [1,2,3]. In general, higher ionic mobility is considered to be a favorable property of an electrolyte, irrespective of the latter being a purely ionic liquid at room temperature (RTIL) or an ion-molecular system, in which an ionic concentration is sufficiently high to merit practical applications [4]. While many RTILs exhibit promising physical and chemical properties (low volatility, thermal stability, suitable electrochemical windows, wide liquid ranges, etc.), their charge mobility and particle mobility are, at best, mediocre [5]. Enhancement of charge mobility of RTILs is a sensible...
