“…As is known, much effort has been devoted and numerous approaches have been developed, such as constructing a functional layer on the Zn surface to regulate the interfacial electric field, − optimizing the current collector to facilitate Zn 2+ nucleation, , modulating the electrolyte composition to adjust the Zn 2+ solvation shell, , modifying the composition of the separator to promote Zn 2+ diffusion, , etc. Among these strategies, the operation on current collectors, Zn anodes, and separators is complicated and costly, and optimizing the electrolyte composition is much more promising, because it can directly modulate the solvation shell of hydrated Zn 2+ and effectively suppress the H 2 O-induced side reactions.…”

The attractive advantages of the Zn metal anode and water-based electrolyte, such as inherent safety and low cost, endow the zinc-ion batteries (ZIBs) with great potential in the future energy storage market. However, the severe surface side reactions and dendrites affect the service lifespan and electrochemical performance of ZIBs. Herein, a bifunctional electrolyte additive, L-ascorbic acid sodium (LAA), has been added into ZnSO 4 (ZSO) electrolyte (ZSO + LAA) to settle the above issues of ZIBs. On the one hand, the LAA additive tends to adsorb on the Zn anode surface to generate a H 2 O-resistive passivation layer, which can effectively isolate the H 2 O corrosion and regulate the Zn 2+ ion 3D diffusion, thus inducing a uniform deposition layer. On the other hand, the strong adsorption capacity between LAA and Zn 2+ can transform the solvated [Zn(H 2 O) 6 ] 2+ into [Zn(H 2 O) 4 LAA], thus reducing the coordinated H 2 O molecules and further suppressing side reactions. With this synergy effect, the Zn/Zn symmetric battery with the ZSO + LAA electrolyte can deliver a cycle life of 1200 h under 1 mA cm −2 , and the Zn/Ti battery also presents an ultrahigh Coulombic efficiency of 99.16% under 1 mA cm −2 , greatly superior to the batteries with the ZSO electrolyte. Additionally, the effectiveness of the LAA additive can be further verified in the Zn/MnO 2 full battery and pouch cell.

The Zn metal anode suffers from uncontrollable dendrite formation and intricate parasitic reactions that dramatically impede the commercialization of aqueous Zn metal batteries (AZMBs). This st proposes synergistic strategies for facilitating Zn 2+ migration kinetics and regulating surface energy to achieve dendrite-free Zn deposition and suppressing self-corrosion by covering Zn anode with multifunctional covalent organic frameworks possessing sulfonate-rich (SO 3 H) covalently-tethered nanochannels (SCOFs). Benefiting from the vital interplay between SO 3 H and Zn 2+ , the SCOFs coatings form ample Zn 2+ accelerated transport channels to extract Zn 2+ from the electrolyte quickly, thereby promoting rapid desolvation of hydrated Zn 2+ , enhancing ion replenishment capability, and guaranteeing a steady stream of Zn 2+ flux for endowing uniform and compact nucleation. Additionally, the zincophilic SCOFs significantly reduce the surface energy of the Zn (002) crystal plane, inducing preferentially crystallographic (002) orientation electroplating growth. Consequently, the SCOFs-coated Zn anodes (SCOFs@Zn) demonstrate an excellent lifespan up to 4000 h at 5 mA cm −2 , 1 mAh cm −2 , and 3000 h at 5 mA cm −2 , 2 mAh cm −2 . Meanwhile, the full cell paired with the MnO 2 cathode sustains remarkable reversibility within 1000 cycles. The synergistic approach to manipulating ion migration and surface energy provides new insights into developing highly stable AZMBs.
