This work summarizes state-of-the-art results achieved by combining, in a synergetic approach, the outcome obtained by electrochemical, spectroscopic and theoretical methods. A number of selected case-studies are reported, where such a synergetic approach enables to draw a complete picture of complex experimental systems.
Finally, the relevance of the combined experimental and theoretical approach in solid-state electrochemistry, a territory amidst novel concepts in solidstate electronics, is recapped.
