"description": "The zinc-ion battery is one of the promising candidates for next-generation energy storage devices beyond lithium technology due to the earth abundance of Zn materials and their high volumetric energy density (5855 mA h cm-3). To date, the formation of Zn dendrites during charge-discharge cycling still hinders practical application. It is, therefore, crucial to understand the formation mechanism of the zinc dendritic structure before effectively suppressing its growth. Here, the application of operando digital optical microscopy and in-situ lab-based X-ray computed tomography (X-ray CT) is demonstrated to probe and quantify the morphologies of zinc electro-deposition/dissolution during multiple galvanostatic plating/stripping conditions in symmetric Zn||Zn cells. With the combined microscopy approaches, we directly observed the dynamic nucleation and subsequent growth of Zn deposits, the heterogeneous transportation of charged clusters/particles, and the evolution of ‘dead’ Zn particles via partial dissolution. Zn electro-deposition at the early stage is mainly attributed to activation, whilst the subsequent dendrite growth is dominated by diffusion. A high current not only facilitates the formation of sharp dendrites with larger mean curvature at their tips, but also leads to dendritic tip splitting and thus generating the hyper-branching morphology. This approach offers a direct opportunity to characterise dendrite formation in batteries with a metal anode in the laboratory.",
