Tuesday publication post! 📖 In this newest publication from Walid Dachraoui, Ruben Simon Kühnel, Corsin Battaglia and Rolf Erni, the Poseidon AX 💧 system was used to investigate the nucleation and growth mechanisms of zinc dendrites in aqueous zinc #batteries (AZBs). By directly observing Zn deposition dynamics in liquid environments, the authors reveal how early-stage crystallographic evolution governs the formation of hazardous dendritic structures.
Key highlights:
🔬 The Poseidon AX system enabled real-time EC-LC-STEM visualization of Zn dendrite evolution during electrochemical cycling
⚡ Reveals a multistep dendrite growth pathway beginning with localized nucleation of hexagonal Zn species at the electrode–electrolyte interface
🔋 Findings provide new insight into the mechanisms driving unsafe Zn growth in aqueous zinc-ion battery systems
This work establishes a deeper understanding of zinc dendrite formation by connecting early nucleation behavior with large-scale dendritic evolution. The findings offer valuable guidance for developing safer and more stable aqueous and hybrid zinc battery technologies.
