Electrochemical energy storage is a key component for electromobility and the efficient use of renewable energy sources. Pushing batteries to higher energy and power densities is full of challenges. This talk will compile the different points of view from physicists, chemists and engineers. Selected examples are shown to demonstrate how modern characterisation techniques can bridge fundamental physics with the development of new materials for a sustainable energy technology. The high level of complexity and the huge number of structural and chemical degrees of freedom in the design of electrochemical cells require a solid understanding of the most relevant underlying working and degradation mechanisms for a systematic optimization of such energy storage devices. Most of the lessons learned from Li-ion batteries also apply for the so-called “post-Li” battery concepts and are discussed.
