“…28 Recently, the effect of the binary additives (SLS & NaF) on the electrochemical performance of an undivided SLRFB has been studied and reported. 29 The electrochemical performance has been compared in terms of the individual electrode performance, kinetic parameters (limiting current density, exchange current density & Tafel slope), crystallographic phases and surface morphology of the electrodeposits. It has been observed that NaF additive improving the kinetics of Pb 2+ /Pb and Pb 2+ /PbO 2 reaction significantly as compared to the primitive electrolyte or with SLS additive.…”

“…The slope of the voltammogram through the reduction potential (as shown in the inset) being lower for SLS additive compared to that of the without additive case reflects the slow kinetics of electron transfer when the additive is present in the solution. Recently, the effect of SLS additive on the electrode kinetics of Pb 2+ /Pb redox couple was studied by Shukla et al 29 The CVs of Pb 2+ /Pb redox couples with and without additive were recorded in a three-electrode undivided flow cell as shown in Fig. 4.…”

“…17 Suman et al have also observed the electrolyte's discoloration while cycling the SLRFB in the presence of SLS. 29 At the end of 200 charge/discharge cycles, a thick layer of SLS was deposited on the cathode, decreasing SLS concentration in the electrolyte, leading to the formation of Pb dendrites with further cycling of SLRFB. SLS, an anionic surfactant having a negatively charged hydrophilic end, tends to migrate towards the cathode due to the electrophoretic effect and gets irreversibly adsorbed at the cathode.…”

“…Shukla et al have also studied the effect of NaF as an electrolyte additive on the physicochemical and electrochemical performance of cathode. 29 All the experiments were performed in an undivided flow cell comprised of carbon felt as electrodes with an active area of 24 cm 2 and electrolyte 1 M lead methanesulfonate salt + 0.5 M MSA + 100 mM NaF. It has been reported that NaF improves the kinetics of Pb 2+ /PbO 2 redox couple compared to that in the absence of additive.…”

“…Recently, Shukla et al have reported SLRFB with >100 charge/ discharge cycles with CE > 90% by using NaF and SLS additives. 29 They have extended the cycle life to 300 by employing the auxiliary gas diffusion electrode. 56 The auxiliary electrode was operated as an air electrode to dissolve back the remaining Pb present on the anode in the discharged state of the cell.…”

Soluble lead redox flow batteries (SLEFBs) are attractive for their undivided flow channel design over other flow battery chemistries, which require an expensive membrane/separator. In an SLRFB, lead metal and lead dioxide are plated on the negative and positive electrodes from a single electrolyte reservoir containing soluble lead(II) species. Although the membrane-less cell configuration bestows SLRFBs cost-effectiveness over other flow batteries, there are challenges associated with the plating of PbO2, Pb dendrite formation, and the presence of parasitic reactions. This review focuses mainly on the present status and major challenges of SLRFBs. The solutions to prevent the dendritic growth of Pb metal, accelerate the redox kinetics of Pb2+/PbO2 redox couple, and suppress the oxygen evolution at cathode are discussed in detail. The role of electrolyte concentration, electrolyte additives, current density, charging time, and temperature on the phase change and surface morphology of the PbO2 electrodeposit are extensively reviewed. In addition, the modification to the electrolyte in terms of the additive chemistry improving the electrochemical performance and cycle life of SLRFBs are discussed. Finally, the aspects of cell design on improving the performance at a lab-scale as well as stack level are highlighted.

Daniell cell is the first battery to be used in practice and is considered to be the first practice of electrometallurgy, which is the bridge connecting electrometallurgy and electrochemical energy storage. Although Daniell cell is later replaced by other batteries due to the unrechargeable characteristic and the self‐discharge side reaction, the research on the electrode based on the deposition/dissolution mechanism inspired by Daniell cell has never been stopped due to its incomparable advantages compared with the electrodes based on the ion insertion/extraction mechanism and the solid‐phase redox reaction mechanism. In recent years, increased focus has been placed on the research of deposition/dissolution battery (DDB), in which two deposition/dissolution chemistries are coupled. In this review, the evolution process from the origin of electrometallurgy to the discovery of energy storage batteries of DDBs is briefly introduced. Furthermore, two main types of DDBs, including Pb‐based DDBs and Mn‐based DDBs, are analyzed systematically, and the critical issues and solutions are outlined and discussed in depth. Finally, personal perspectives on the future research directions are highlighted, aiming to provide guidance for performance improvement and the practical application of DDBs.
