The fluidity of aqueous electrolytes and undesired H2 evolution reaction (HER) can cause severe interfacial turbulence in aqueous Zn metal batteries (ZMBs) at deep cycling with high capacities and current densities, which would further perturb ion flux and aggravate Zn dendrite growth. In this study...
