Zinc ion batteries are promising candidates for large-scale energy storage systems. However, they suffer from the critical problems of insufficient cycling stability due to internal short-circuiting by zinc dendrites and zinc metal orphaning. In this

Aqueous zinc (Zn)-based flow batteries are an attractive option for energy storage systems due to their inflammability and high energy density. However, Zn dendrite formation, which causes internal short circuiting and capacity drop, limits the long-
