20.500.12556/DiRROS-23596 Formation and discharge of Zn aponge anodes, followed by synchrotron hard X-ray Imaging The fabrication of engineered Zn anodes often relies on different forms of ZnO as the material in direct contact with the alkaline aqueous electrolyte in the pristine assembled cell state. Of course, in this case, the as-assembled cell is in the discharged state and requires an initial charging step, or “formation”, to generate active metallic Zn. The formation of ZnO-based anodes is a complex process the control of which calls for an in-depth understanding of electrochemical phase growth. In fact, formation gives rise to morphochemical imprinting, profoundly impacting the electrode functional performance. The present work contributes to the understanding of the formation of Zn sponge electrodes, combining electrochemistry and synchrotron-based X-ray imaging. Specifically, we employed dynamic in operando radiography to select the potentiostatic formation conditions that exclude hydrogen-induced damaging of the sponge structure. Subsequently, formation and the subsequent first discharge are followed by time-lapse in situ tomography, allowing to track the early structural evolution of the sponge electrode and the Zn/ZnO phase distribution. zinc anode zinc battery zinc sponge X-ray microtomography synchrotron radiation in situ in operando cinkova anoda cinkova baterija cinkova goba rentgenska mikrotomografija sinhronsko sevanje in situ in operando true false true American Chemical Society Angleški jezik Slovenski jezik © 2025 The Authors Neznano 2025-09-11 07:48:01 2025-09-11 07:58:26 2025-10-24 03:54:36 0000-00-00 00:00:00 2025 0 0 str. 10265-10276 iss. 14 Vol. 8 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-07-13 621.35/.36 2574-0962 10.1021/acsaem.5c01110 247762691 https://pubs.acs.org/doi/10.1021/acsaem.5c01110 1 e2c1b7a5-8ed2-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=34908 RAZ_Bozzini_Benedetto_2025.pdf RAZ_Bozzini_Benedetto_2025.pdf 1 01557A065FF34B53487D9BB07606765A 3c7d8aff5ab7b038cba9c2d7422f2b06deaff0bcddb2b879cd4a03a6f4e91eea 464bcad8-8ed4-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=34909 Zavod za gradbeništvo Slovenije 0 0 0
