Basal Plane Graphene Coated Zn Powder for High Performance Aqueous Zn Metal Batteries. [PDF]
Adv Sci (Weinh)A mechanofusion‐driven dry coating forms a hydrophobic graphene shell on Zn powder, stabilizing the electrode‐electrolyte interface. This basal‐plane‐rich protective layer modifies the Zn2+ solvation environment and promotes preferential growth along the (002) plane, suppressing dendrite and parasitic reactions.
