The increase of global Earth’s temperature is linked generally to greenhouse gas emission that never ceased to increase during the last century. E-mobility and storage are the leitmotif to reduce directly the amount of CO₂ emission. In both cases, batteries might play a key role to reduce the greenhouse emission. To date, Li and post-Li ion batteries are intensively studied and their deep investigations by sophisticated techniques, in particular operando, are crucial to solve all the issues. Data gathered from advanced operando techniques, at large scale facilities or in-house, are crucial only if they are obtained from reliable electrochemical cells that mimic properly the real operation of battery materials, which is never an easy task. Hence, the design of such cells has to be fit to the technique of choice and meet all the necessary requirements. Once a proper design is found, the surface, the bulk, the interfaces, and finally the combination of those can be studied simultaneously and lead to the elucidation of complex reaction mechanisms, thus further improving the battery technology. This symposium will focus on the current progress made in the field of advanced in situ and operando characterizations (experimentally and theoretically) with a special focus on the understanding and improvement of bulk-to-interfacial issues including also safety aspects. Worldwide specialists will present new science, techniques, data analysis and propose a deeper understanding of electrochemical energy-based system beyond the state-of-the-art.
