Exploring the influence of pH and current density on zinc morphology via the electrodeposition method — •Dharani Madhavi Bundhooa, Jiajia Qiu, Huaping Zhao, and Yong Lei — Fachgebiet Angewandte Nanophysik, Institut für Physik & IMN MacroNano, Technische Universität Ilmenau, 98693 Ilmenau, Germany

This study investigates the impact of pH and current density on the morphology of zinc electrodeposits, intending to fabricate a dendrite-free anode. Characterization through SEM and XRD demonstrated that lower pH levels fostered more uniform growth, resulting in reduced dendritic formations. Moreover, tuning the current density for optimal values further enhanced homogenous growth, providing essential insights for the design of composite anode materials. The findings highlight the connection between zinc deposit morphology and superior electrochemical performance in relation to the applied electrodeposition current density and the pH of the electrolyte.
