Aqueous zinc-ion batteries have drawn increasing attention due to the intrinsic safety, cost-effectiveness and high energy density. However, parasitic reactions non-uniform dendrite growth on Zn anode side impede their application. Herein, a multifunctional additive, ammonium dihydrogen phosphate (NHP), is introduced regulate uniform zinc deposition suppress reactions. The results show that NH
Abstract Routine electrolyte additives are not effective enough for uniform zinc (Zn) deposition, because they hard to proactively guide atomic‐level Zn deposition. Here, based on underpotential deposition (UPD), we propose an “escort effect” of at the atomic level. With nickel ion (Ni 2+ ) additives, found that metallic Ni deposits preferentially and triggers UPD Ni. This facilitates firm nucleation growth while suppressing side reactions. Besides, dissolves back into after stripping with...

Abstract Sodium super‐ionic conductor (NASICON)‐structured phosphates are emerging as rising stars cathodes for sodium‐ion batteries. However, they usually suffer from a relatively low capacity due to the limited activated redox couples and intrinsic electronic conductivity.

Aqueous zinc-ion batteries (AZIBs) have experienced a rapid surge in popularity, as evident from the extensive research with over 30 000 articles published past 5 years. Previous studies on AZIBs showcased impressive long-cycle stability at high current densities, achieving thousands or tens of cycles. However, practical low densities (<1C) is restricted to merely 50-100 cycles due intensified cathode dissolution. This genuine limitation poses considerable challenge their transition...
