The Cover Feature represents a roadmap to the optimisation of Li‐ion batteries for electromobility applications. As the positive electrodes (i. e., cathodes) currently represents the bottleneck for increasing the energy density of a Li‐ion system, in order to enable the next‐generation of high energy density Li‐ion batteries, more attention needs to be focused on the investigation of the surface layer (or interphase) formed on these electrodes. Such interphase might behave as a protective layer allowing higher operating potentials, and therefore higher energy density of the battery, without compromising the stability of the electrolyte and the cycle life of the Li‐ion cell. Thus, it is of fundamental importance to combine the knowledge obtained from many diverse analytical tools, both established and novel, in order to gain a broader and more comprehensive view of the role and the nature of such surface layers.
