In article number 2000276, Gennady Cherkashinin and co‐workers describe an experimental approach to predict interfacial chemical reactions in battery systems. This new approach is of particular interest for the development of a new generation of all‐solid‐state 5 V Li ion batteries. The key parameters are the electrochemical and ionization potentials of the involved materials. Interface stability is achieved by pulling apart the ionization potentials of cathode and electrolyte as indicated by the two hands. The experimental investigation of the internal interface of a typical solid‐state battery is sketched on the right side. The suppression of detrimental interface reactions is an important step in the development of high energy density batteries for e‐mobility.
