Commercial cell formats such as 18650 cylindrical cells or 2032 coin cells represent a reproducible and well-tested standard regarding the electrochemical performance. However, their size, geometry (jelly-roll), and the materials used (stainless steel casing), make it challenging if not impossible to collect meaningful synchrotron characterization data – except when using very high energy beams. Therefore, for synchrotron measurements the battery community heavily relies on custom-built operando cells and setups, that are optimized to reduce background signals and other spurious artifacts.
