“…12 Despite having been in development since 1970s, RFBs have had limited penetration into the energy storage market. 15,16 Since the initial RFB chemistry, several different redox systems have been studied, including aqueousand non-aqueous electrolytic systems, [17][18][19] metallic or non-metallic electrodes and/or current collectors, membranes as well as means for scalingup. 20,21 The most widely studied aqueous inorganic systems include the all-vanadium redox ow battery (VRFB), the zincbromine redox ow battery (ZFB), ICFB and the polysuldebromine redox ow battery (PSB).…”

“…sites, favoring stable lateral growth instead of unstable outgrowth, but they also impact a number of other processes related directly or indirectly with electrocrystallization, in a way that still escapes rationalization. Among the various families of organic compounds that have been considered, non‐ionic polymers, such as PEG 800, show interesting performances in terms of charge and half‐cell efficiencies, in addition to dendrite growth inhibition .

Electrodeposition of Zinc from Alkaline Electrolytes Containing Quaternary Ammonium Salts and Ionomers: Impact of Cathodic‐Anodic Cycling Conditions

Dendrite suppression capabilities are key factors for the practical deployment of rechargeable Zn-based batteries. We propose a systematic electrochemical investigation, accompanied by SEM imaging, of the impact of representative quaternary ammonium (QA) salts and ionomers on Zn electrodeposition. Both cathodic and anodic processes were considered, because insoluble corrosion products can impact subsequent electrodeposition during cycling. We used simple cyclic voltammetry methods and developed a framework for their quantita-tive interpretation in terms of physically legible descriptors. QAbased additives tend to suppress the accumulation of anodic products, favoring symmetric cathodic and anodic activation. Poly di-allyl di-methyl ammonium chloride (PDADMAC), a polymer with limited cathodic reactivity, was found to be a promising additive that minimizes cathodic and anodic irreversibility and stabilizes mass transport, possibly owing to the formation of a single-ion conducting cathodic film.

choices for such systems due to their attractive features of high safety, low cost, and long cycle life. [3] In a typical ZFB, metallic zinc (Zn) plating/stripping, processing low electrochemical potential (−0.762 vs the standard hydrogen electrode (SHE)), rapid reaction kinetics, and environmental friendliness, is well suitable for anodic electrochemical reaction. [4] However, the realization of high cycling stability and long life of a ZFB has to face the intricate challenges from Zn anode: dendrite formation, as a result from inhomogeneous Zn plating during the process of charging, leads to internal short circuit failure and increase in surface area of Zn anode, which accelerates corrosion and decreases the utilization of Zn deposited onto anode; during the process of discharging. The dendrite formation will aggravate the uneven Zn stripping and the formation of dead Zn, and then decrease the coulombic efficiency (CE). [5] Therefore, uniform and dense Zn deposition is of great necessity for a long life ZFB. However, it is extremely challenging to obtain an even and dense deposition of Zinc for rechargeable ZFBs. [6] To overcome this problem, the addition of inorganic, organic, and polymeric additives is proposed to control the dendritic growth. [7] Unfortunately, these usually increase polarization, or are expensive and even environmentally hazardous. On the other hand, these proposals mostly address the problem from the perspective of electrolyte. It is full of strategic importance to explore other methods (for example, anode modification), which may work better in combination with additives. Moreover, many methods related to aqueous Zn-based battery system have been provided, e.g., 3D architecture Zn, backsideplating Zn, water-in-salt electrolyte, construction of artificial solid-electrolyte interface, ionic liquid containing nickel triflate and metal-organic framework host. [8] Much progress has been made in the aspect of inhibition of dendrite growth. However, considering their real medium and the state-of-art configuration, these methods cannot be transplanted to ZFBs. Therefore, there is an urgent need to propose effective methods to inhibit dendrite growth especially focusing on ZFBs.Herein, we propose and fabricate a multifunctional binderfree tin (Sn) modified 3D carbon felt anodic host (SH) for zinc deposition via a facile and scalable strategy by magnetron sputtering. The results demonstrated that: according to the experimental and computational simulation results, the Zinc (Zn) plating/stripping is a promising anodic electrochemical reaction for aqueous batteries because of its high safety, low cost, two electron transfer, and rapid reaction kinetics. However, the notorious dendrite growth of Zn has become one of the biggest obstacles hindering its further commercialization. A multifunctional binder-free tin (Sn)-modified 3D carbon felt anodic host (SH) is constructed for aqueous zinc-based flow batteries (ZFB) via a facile and scalable strategy. Compared with the pristine carbon felt host (...
