      abstract     = {The continued expansion of renewable energy sources
                      resulted in an increased demand for safe and affordable
                      energy storage solutions with high volumetric energy
                      density. Alternative battery systems, such as zinc-air
                      batteries (ZABs) and zinc-ion batteries (ZIBs) not only use
                      affordable, safe and highly abundant materials, but their
                      high theoretical capacity and volumetric energy density make
                      them well suited for grid and long-term storage. However,
                      their cyclability and efficiency are negatively impacted by
                      the metallic zinc anodes inherent shape change, produced by
                      uneven deposition and dendritic growth. To advance the more
                      widespread application of zinc-based batteries it is
                      therefore crucial to understand the mechanisms behind
                      nucleation and causes for dendrite formation on the
                      electrode surface.This work presents a correlative study
                      combining tomography and diffraction methods to gain
                      valuable insights into deposition processes at the zinc
                      anode surface. With the information gained from X-ray
                      computed tomography (XCT), diffraction contrast tomography
                      (DCT) and electron back-scatter diffraction (EBSD)
                      conclusions about the impact of the substrate crystal
                      structure on zinc nucleation and dendritic growth could be
                      drawn. The analyzed symmetrical model system included wire
                      electrodes to minimize attenuation by reducing the amount of
                      highly absorbing material in the field of view. The tip of
                      the observed electrode is characterized ex situ using DCT
                      and EBSD to capture the pristine state of the crystal
                      structure. The pristine morphology and its evolution are
                      recorded by means of a custom 2D/3D in-operando XCT imaging
                      protocol to observe deposition and dissolution processes. In
                      post-mortem scans, the state of the electrode is examined
                      using the three techniques to evaluate the effects of
                      electrochemical processes on the morphology and crystal
                      structure. By combining these methods, the locations of
                      nucleation sites and the development of deposits on the
                      electrode surface could be correlated with the initial
                      crystal structure, providing insights into the mechanisms of
                      shape change and dendrite formation.},
