Electrochemistry consists of two core fields: electrodics and ionics. Electrodics mainly deals with the charge transport at the electrified interface, while ionics concerns on the ion transport and speciation in ionic media. For the last century, the electrochemistry society has focused on electrodics with appreciable achievements, whereas ionics has seen no noticeable progress since the theory of Debye and Huckel. This indifference to ionics seems to be partly due to the misunderstanding that ionics is an old-fashioned, no-further-jobs-to-do history. Also, it may be ascribed to our relinquishment to conquer the super-complex area, obviously due to the absence of the appropriate tools and theories. However, over the past decades, we have had to confess our ignorance on the ion conduction and solution structure in the concentrated electrolytes of the energy storage/conversion devices (e.g., batteries, fuel cell, capacitors). At the same time, we have witnessed remarkable advances in the analytical instruments and computing power, which can provide us with magnificent gadgets to tackle the impregnable topic.
In this talk, as a humble first-step of the long journey toward ionics, we’ll introduce some of our recent findings on the ionic conduction behaviors in the Li-ion battery electrolytes, in an association with the ion-solvent interaction as investigated using dielectric relaxation spectroscopy as well as conventional ones including Raman and pulse-field-gradient NMR.
