In article number 1902915, Kaili Zhang, Wenjun Zhang and co‐workers investigate the impacts of anions and concentrations of a variety of Zn‐containing aqueous solutions on Zn stripping/plating efficiency. It is demonstrated that dendrite growth and byproduct formation can be suppressed during Zn plating, and the competitive hydrogen evolution reaction is restrained by using a 3 m Zn(CF 3 SO 3 ) 2 electrolyte. As a result, a high Zn stripping/plating efficiency is achieved. Furthermore, based on this electrolyte, a novel hybrid supercapacitor comprising Zn foil and porous carbon derived from chemically activated graphene is developed which delivers high energy density and an ultra‐long lifespan.
