      abstract     = {Poly(ethylene oxide) (PEO)-based composite electrolytes
                      (PCEs) are considered as promising candidates for
                      next-generation lithium-metal batteries (LMBs) due to their
                      high safety, easy fabrication, and good electrochemical
                      stability. Here, we utilize operando grazing-incidence
                      small-angle and wide-angle X-ray scattering to probe the
                      correlation of electrochemically induced changes and the
                      buried morphology and crystalline structure of the PCE.
                      Results show that the two irreversible reactions, PEO-Li$^+$
                      reduction and TFSI– decomposition, cause changes in the
                      crystalline structure, array orientation, and morphology of
                      the PCE. In addition, the reversible Li plating/stripping
                      process alters the inner morphology, especially the
                      PEO-LiTFSI domain radius and distance between PEO-LiTFSI
                      domains, rather than causing crystalline structure and
                      orientation changes. This work provides a new path to
                      monitor a working battery in real time and to a detailed
                      understanding of the Li$^+$ diffusion mechanism, which is
                      essential for developing highly transferable and
                      interface-stable PCE-based LMBs},
