Recent Progress in High‐voltage Aqueous Zinc‐based Hybrid Redox Flow Batteries

“…[29] However, the intrinsically slow reaction kinetics of organic solvent often regulated the rate performance of non-aqueous RFBs. [30] As an alternative solution to the tradeoff between cell voltage and rate performance in liquid-liquid based RFBs, many researchers have been focusing on the aqueous hybrid redox flow batteries (HFBs) using that metal deposition/dissolution-based metal redox couples by using the heterogeneous chemistry between solid-liquid interfaces. [31,32] To date, HFBs have gained great attention due to their safe, abundant resources, and environmental friendliness.…”

“…For instance, modifying the molar structure of benzene‐based organic active species showed good cycle life for 1,000 cycles and a cell potential of 2.5 V in the non‐aqueous RFBs [29] . However, the intrinsically slow reaction kinetics of organic solvent often regulated the rate performance of non‐aqueous RFBs [30] .

A Method to Inhibit Disproportionation of Mn3+ for Low-Cost Mn–Fe All-Flow Battery

“…15−18 Efforts to mitigate these problems include adding additives to zinc electrolytes to suppress the growth of zinc dendrites and constructing composite membranes to hinder crossover of polysulfide anions. 19,20 These efforts are commendable but do not outright solve problems inherent with the design of these flow battery architectures.…”

“…ARFBs are safe and possess high salvage value, and costs of operation and maintenance are considerably lower compared to the competition. − Among ARFBs, the vanadium flow battery (VFB) which utilizes VOSO 4 as its active species is the most mature and well-studied technology. , Although VFBs are efficient, mining and extracting vanadium is costly and environmental harmful. Alternatives such as zinc–iron, zinc–iodine, iodine–sulfur, and aqueous organic flow batteries have been considered, yet they are not without limitations. − To provide some examples, dendrite formation occurs extensively in Zn metal anodes used in zinc-based flow batteries, polysulfide anions cause crossover effects, and redox-active organic molecules are notorious for structural degradation leading to capacity decay. − Efforts to mitigate these problems include adding additives to zinc electrolytes to suppress the growth of zinc dendrites and constructing composite membranes to hinder crossover of polysulfide anions. , These efforts are commendable but do not outright solve problems inherent with the design of these flow battery architectures.…”
