“…We previously demonstrated that no additional side reactions are observed with NaOAc addition in SLFBs and that the quality of deposited PbO 2 film is shown to be highly related to the cycle life of SLFBs. 12 The beneficial effects of NaOAc additive on SLFBs is manifested by comparing two different electrolytes: a standard electrolyte with 50 mM NaOAc addition and one without NaOAc. Table 1 summarizes the life span of the aforementioned two SLFBs under various COE, whereas we previously defined the parameter COE as the ratio of the actual-to-theoretical conversion of the electrolyte to indicate material utilization in SLFBs.…”

“…Previously, we reported that with adequate amounts of NaOAc additive in methanesulfonate electrolyte, the serviceable life and capacity of SLFBs can be materially enhanced. 12 This paper focuses on rationalizing how NaOAc can enhance electrodeposit quality, reduce undesired oxygen evolution, and also improve the mechanical properties of platted PbO 2 . In addition, the homogenized PbO 2 grain orientations induced by NaOAc is further linked to the shedding of PbO 2 slurries during SLFB operation.…”

Soluble lead flow batteries (SLFBs), a potential form of large-scale energy storage, are currently facing the challenge of short cycle life. We previously demonstrated that by adding sodium acetate (NaOAc) in the electrolyte, the life span of SLFBs can be significantly extended. Here, we aim to elucidate the effect of acetate additive on SLFBs. We find that the mechanical strength of the PbO 2 layer plated by acetate-assisted electrolyte is materially enhanced. Through electron backscattering diffraction, certain preferred orientations of deposited PbO 2 are observed when plated without acetate additive, while random orientations are better preserved when plated with acetate additive. Via Brunauer−Emmett−Teller measurements, we find that porosity and surface area are both comparatively smaller in the acetate-assisted PbO 2 deposits, while the rate of oxygen evolution reaction (OER) is shown to be drastically reduced on PbO 2 plated with NaOAc-assisted electrolyte. We further propose that the OER pathway is suppressed by the additive due to acetate-ion adsorption at superficial PbO 2 sites, and in turn facilitates PbO 2 plating. These further discoveries are of critical value for further extending cycle life and enabling SLFB technology.

Shunt currents in membraneless soluble-lead-redox-flow-batteries (SLRFB) are observed in open-circuit condition and found to depend on size of the stack, manifolds, flow rates and charge/discharge parameters. Ramifications of shunt currents on the performance of membraneless SLRFB stacks with internal and external manifolds are reported. In the case of stacks with 3, 5 and 7-cells and internal manifold design, the charge current for the middle cell decreases by 3.3%, 6%, and 8.5%, while the discharge current increases by 2.6%, 5.5%, and 6.6% , respectively, for 3 A charge/discharge current. By contrast, no such adverse effect is observed for external manifold design. The current – potential studies show that while the stacks comprising 3 and 5-cells deliver a maximum power density of 35 mW/cm2, which declines to 15 mW/cm2 for the 7-cell stack with internal manifold design, while the power density remains invariant at 50 mW/cm2 for stacks with external manifold design. An 8-cell stack of 12 V, 50 mAh/cm2 specific capacity and 273 Wh energy storage capacity with 64% energy efficiency is also reported which shows good cyclability over 100 cycles with 95% coulombic efficiency when cycled at 20 mA/cm2 current density for 1h duration.

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.
