We have an exciting playground for the development of many green and sustainable technologies by using electric potential to drive thermodynamically demanding and kinetically hindered reactions to occur under mild, nearly ambient conditions. These electrochemical technologies have already advanced significantly, which is encouraging new, intense research in the field on a variety of subjects, from conventional electrowinning and chlor-alkali electrolysis to potential future developments in electrosynthesis and energy-transformation processes. We can only just barely quench our curiosity, which will keep us breathless for many years to come, thanks to instrumental and theoretical innovations that push the limits of our knowledge and produce insights into the electrochemical systems. Innovative techniques, such as those utilising artificial intelligence, sophisticated simulation techniques, and operando analysis with light, electrons, and neutrons, help us understand, for example, the activity of peculiar molecules that arrive at the electrode surface (transport), settle down (adsorption), and shake hands (reaction), or the shifting of ions from the anode side to the cathode side when storing energy in a battery.
