In the S-Br batteries, electrolyte solutions are separated by cation exchange membranes preventing the diffusion of sulfide anions from the negative to the positive half-cells, which would cause the reaction between sulfide and bromine shortening the lifetime of the battery .
The most general classification of flow batteries is based on the occurrence of the phase transition distinguishing two main categories, ‘true’ RFBs, the most studied option, and hybrid systems (HFBs). . Flow batteries are named after the liquid electrolyte flowing through the battery system, each category utilizing a different mechanism.
The viability of a flow battery based on an all-metal containing ILs was proved with the copper-based species [Cu (MeCN) 4] [Tf 2 N]. This IL can act both as the solvent and redox couples due to the copper ion incorporated in its structure. As pointed out before, these types of compounds are characterized by high metal concentrations.
On the other hand, additives are intended to perform other specific functionalities such as the role of sequestrating agents. In this sense, ILs have shown to be effective as sequestrating agents in zinc-based RFBs (Table 2). Table 2. Assessment of Ionic liquids used as supporting electrolytes and additives in redox flow batteries.
Redox flow batteries (RFBs) have emerged as a prominent option for the storage of intermittent renewable energy in large and medium-scale applications.
