In order to realize future energy storage technology development and commercialization, the field must have fundamental knowledge and understanding of materials and material interactions to serve as the foundation. Scientists seek to understand the reaction mechanisms of electrochemical systems in detail at the material level, component level and system level. Such information will help to pin point the mechanisms responsible for outstanding electrochemistry as well as the root causes of unsatisfactory performance of the existing materials. Detailed understanding of the mechanisms taking place within energy storage systems benefit significantly from characterization methods utilizing in-situ and operando approaches. Case studies of Fe, Mn and V based battery systems will be described including characterization methods providing spatially and temporally resolved information.
