Electrochemical energy storage and conversion is of critical importance for our future sustainable, environmentally friendly energy supply. Due to this importance, significant research and development efforts are undertaken worldwide in order to improve our understanding of electrochemical processes at electrolyte/electrode interfaces and to develop more efficient electrochemical devices such as electrocatalysts, fuel cells and batteries. Many concepts still used today in electrochemistry are rooted in insightful thermodynamical concepts developed more than one century ago. Thermodynamics is a field that deals with measurable macroscopic physical quantities, but a full understanding of the nature of these quantities requires a connection to microscopic properties via statistical mechanics. In this talk, I will try to illustrate this connection using recent examples of first-principles studies addressing structures and processes in electrocatalysis and batteries on the atomic level.
