Bromine-Side Electrode Functionality

The mechanisms and kinetics of reactions at the bromine-side electrode are generally agreed to be more complicated than those at the zinc-side electrode. This complexify is primarily attributed to the presence and interactions of multiple versions of bromide species (Br , Bri, Brs, etc.) in the electrolyte solution, as well as the electrochemical and possibly surfactant-like effects of the particular BSA used. The structures and bonding present in polybromides have been studied using periodic density functional theory and found to have closed-shell interactions between the Br anion and multiple Br2 species [16]. A recent smdy has shown that high-order bromide anions can exist in ionic hquid systems, including a polymeric [17]. [Pg.82]

Additives might also affect the maximum obtainable efficiency from the electrolyte as a whole. For instance, hypochlorite and hypochlorous acid can assist in Br oxidation [54], although carefiil pH control would be required to avoid deviating out of the narrow working range required for ZBB operation. Furthermore, additional in-depth studies of the mechanism and kinetics of the Br2/Br redox couple are required at various types of untreated and functionalized carbon-based electrodes, both with and without the use of additives. Comprehensive modelling with experimental validation of O2 evolution at the bromine-side electrode and consequent impacts on ZBB efficiency also need to be carried out. [Pg.92]
