摘      要：Zn-based electrochemical energy storage(EES)systems have received tremendous attention in recent years,but their zinc anodes are seriously plagued by the issues of zinc dendrite and side reactions(e.g.,corrosion and hydrogen evolution).Herein,we report a novel strategy of employing zincophilic Cu nanowire networks to stabilize zinc anodes from multiple *** to experimental results,COMSOL simulation and density functional theory calculations,the Cu nanowire networks covering on zinc anode surface not only homogenize the surface electric field and Zn^(2+)concentration field,but also inhibit side reactions through their hydrophobic ***,facets and edge sites of the Cu nanowires,especially the latter ones,are revealed to be highly zincophilic to induce uniform zinc nucleation/***,the Cu nanowire networks-protected zinc anodes exhibit an ultralong cycle life of over 2800 h and also can continuously operate for hundreds of hours even at very large charge/discharge currents and areal capacities(e.g.,10 mA cm^(-2)and 5 mAh cm^(-2)),remarkably superior to bare zinc anodes and most of currently reported zinc anodes,thereby enabling Zn-based EES devices to possess high capacity,16,000-cycle lifespan and rapid charge/discharge *** work provides new thoughts to realize long-life and high-rate zinc anodes.
