Soluble lead redox flow battery (SLEFB) is attractive for its undivided cell configuration over other flow battery chemistries, which require an expensive membrane/separator. In the 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 SLRFB 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 mainly focuses on the present status and major challenges of the SLRFB. 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 have been 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 has been extensively reviewed. Besides, the modification to the electrolyte in terms of the additive chemistry improving the electrochemical performance and cycle life of SLRFB has been discussed in this review. Finally, the aspects of cell design on improving the performance at a lab-scale as well as stack level are highlighted.

Redox flow batteries are energy storage devices that have successfully been commercialised and demonstrated on the MW/MWh scale for various power applications, such as renewables capacity firming. The vanadium and zinc-bromine systems, having been developed over several decades, are currently the most advanced. However, their respective limitations have invited research into other chemistries. Soluble lead is one such alternative, in which both electrode reactions involve just one active species, Pb²⁺. The electrolyte is inherently safer than many other systems, and proof-of-concept studies have highlighted its suitability for scale-up. In this thesis, the next stage of this process is reported. Fundamental gaps in electrolyte properties, such as conductivity and viscosity, are explored before extensive charge/discharge cycling experiments are carried out in order to optimise the electrolyte, which includes a novel combination of additives. Traditional soluble lead flow cells did not require a separator, which greatly reduced the cost and complexity of the system. However, by inserting a separator and exploring both a standard division and a novel semi-divided configuration, significant improvements to cell efficiency and lifetime are achieved compared to the literature. A flow cell with 100 cm² electrodes is used to investigate the cell power at different states of charge, peaking at 12.5 W. The results also infer that higher currents on discharge can be drawn than from other well-established chemistries. A method of regenerating a failed cell is also shown, where a series of maintenance cycles brings the system close to its initial conditions. The improvements in this project are used to model a flow battery stack, using another commercial device as a benchmark. Unaddressed gaps in the research for the next stage of scaling-up are also discussed.

Les batteries redox à circulation d'électrolyte constituent une solution prometteuse pour le stockage de masse de l'électricité. Parmi elles, la technologie au plomb soluble dans l'acide méthanesulfonique est intéressante pour son architecture de cellule simplifiée et son faible coût potentiel. Ses performances sont toutefois limitées par l'électrode positive de PbO2 qui implique un faible rendement énergétique et une courte durée de vie des cellules. Le premier objectif de cette thèse est de mieux comprendre les mécanismes électrochimiques en jeu à l'électrode positive. La cinétique de la réaction parasite de production d'oxygène est étudiée. Des mécanismes de dissolution du PbO2 sont proposés et des additifs sont testés pour améliorer sa cyclabilité. Les réponses complexes du potentiel de l'électrode en cyclage galvanostatique sont également interprétées. Le second objectif est de proposer un réacteur innovant comprenant une électrode positive de grande surface spécifique. La structure " nid d'abeilles " est en particulier étudiée. Un réacteur utilisant cette structure est proposé, ses caractéristiques principales sont simulées avec un modèle électrochimique ad hoc, et des prototypes sont fabriquées et testés en cyclage.

Continued emission of green house gases has energized research activity worldwide to develop efficient ways to harness renewal energy. The availability of large scale energy storage technologies is essential to make renewal energy a reliable source of energy. Redox flow batteries show potential in this direction. These batteries typically need expensive membranes which need replacement be-cause of fouling. The recently proposed soluble lead redox flow battery (SLRFB), in which lead ions deposit on electrodes in charge cycle and dissolve back in discharge cycle, can potentially cut down the cost of energy storage by eliminating membrane. A number of challenges need to be overcome though. Low cycleability, residue formation, and low efficiencies are foremost among these, all of which require an understanding of the underlying mechanisms. A model of laminar flow-through SLRFB is first developed to understand buildup of residue on electrodes with continued cycling. The model accounts for spatially and temporally growing concentration boundary layers on electrodes in a self consistent manner by permitting local deposition/dissolution rates to be controlled by local ion transport and reaction conditions. The model suggests controlling role for charge transfer reaction on electrodes (anode in particular) and movement of ions in the bulk and concentration boundary layers. The non-uniform current density on electrodes emerges as key to formation of bare patches, steep decrease in voltage marking the end of discharge cycle, and residue buildup with continuing cycles. The model captures the experimental observations very well, and points to improved operational efficiency and decreased residue build up with cylindrical electrodes and alternating flow direction of recirculation. The underlying mechanism for more than an order of magnitude increase in cycle life of a beaker cell battery with increase in stirrer speed is unraveled next. Our experiments show that charging with and without stirring occurs identically, which brings up the hitherto unknown but quite strong role of natural convection in SLRFB. The role of stirring is determined to be dislodgement/disintegration of residue building up on electrodes. The depletion of active material from electrolyte due to residue formation is offset by “internal regeneration mechanism”, unraveled in the present work. When the rate of residue formation, rate of dislodging/disintegration from electrode, and rate of regeneration of active material in bulk of the electrolyte becomes equal, perpetual operation of SLRFB is expected. The identification of strong role of free convection in battery is put to use to demonstrate a battery that requires stirring/mixing only intermittently, during open circuit stages between charge and discharge cycles when no current is drawn. Inspired by our experimental finding that the measured currents for apparently diffusion limited situations (no external flow) are far larger than the maxi-mum possible theoretical value, the earlier model is modified to account for natural convection driven by concentration gradient of lead ions in electrolyte. The model reveals the presence of strong natural convection in battery. The induced flow in the vicinity of the electrodes enhances mass transport rates substantially, to the extent that even in the absence of external flow, normal charge/discharge of battery is predicted. The model predicted electrochemical characteristics are verified quantitatively through voltage-time measurements. The formation of flow circulation loops driven by electrode processes is validated qualitatively through PIV measurements. Natural convection is predicted to play a significant role in the presence of external flow as well. The hitherto unexplained finding in the literature on insensitivity of charge-discharge characteristics to electrolyte flow rate is captured by the model when mixed mode of convection is invoked. Flow reversal and wavy flow are predicted when natural convection and forced convection act in opposite directions in the battery. The effect of the presence of non-conducting material (PbO on anode) on the performance of SLRFB is studied using a simplified approach in the model. The study reveals the presence of charge coup de fouet phenomenon in charge cycle. The phenomenon as well as the predicted effect of depth of discharge on the magnitude of charge coup de fouet are confirmed experimentally.

This thesis focuses on material and component development and system expansion of a lead acid redox flow battery, a promising large scale energy storage device. We aim to reduce the cost of this energy storage device, so as to facilitate its commercialization. Through integration of power grid and the developed energy storage device, we expect to achieve better load leveling and efficient energy utilization. In this research we concentrated on materials development, electrochemical analyses, additives study, and system expansion for a lead acid redox flow battery. With this research effort, the electrodes are found to be able to endure higher current density and cyclability of the battery is extended. Better battery performance is achieved by using graphite electrode as the positive electrode, nickel plate as the negative electrode, hexadecyl trimethyl ammonium hydroxide as the leveling agent to prevent the growing of lead dendrite, and sodium fluoride as the surface smoother to restrain oxygen evolution. In order to further reduce formation of oxygen on the positive electrode, a layer of β-PbO2 is pre-deposited on the positive electrode before cycling. We found this pretreatment extends the cycle life of the battery to 140 times and maintains the energy efficiency at above 50%, which is much better than a reference system with commercialized composite carbon electrode utilized in fuel cell systems.

Increasing the volumetric energy density of redox flow batteries beyond that of the archetypal all-vanadium system requires the development of highly soluble charge carriers that can store multiple electrons per charge cycle. In this review article we will describe the design and performance of a range of new charge carriers for flow batteries, with an emphasis on those with multi-electron redox properties. These include fullerene derivatives, multifunctional organic systems, metal coordination complexes, and polyoxometalates. Our discussion will include an evaluation of the fundamental physical and electrochemical properties of the charge carriers and their impact on battery performance and energy density.

Abstract This chapter describes electrochemical storage devices. The chapter starts with an introduction of the general characteristics and requirements of electrochemical storage: the open circuit voltage, which depends on the state of charge; the two ageing effects, calendaric ageing and cycle life; and the use of balancing systems to compensate for these effects. Then the four most common electrochemical technologies are described: the lead acid battery, the lithium ion battery, the sodium sulphur battery and the redox flow battery. The primary and secondary reactions are described for each cell chemistry, alongside the ageing effects that occur and the measures that can be taken to reduce them. The discharging behaviour, which is very important for a cell’s operation, is also given for each cell chemistry. The system components and requirements of each electrochemistry are detailed, and each electrochemistry is then used in an application example.

Abstract Energy storage is entering in the energy distribution supply chain due to the global goal of achieving carbon neutrality in human activities, especially those related to energy production. Renewable energies integrated with energy storage play an important role in this framework [1]. The purpose of the study is to evaluate through simulations the impact of new renewable energy technologies in a microgrid to minimize fossil fuels consumption. The case study considers a hybrid microgrid including: a gas microturbine, organic photovoltaic panels (OPV), a point absorber wave energy converter, a vanadium redox flow battery and a load. The microgrid is placed in an offshore hydrocarbon plant near the northern coast of Australia. Firstly, Australian meteorological data have been studied and three seasons identified (named ST1, ST2 and ST3). Then a correlation has been established between meteorological data and OPVs performances, analyzing data collected on OPVs panels installed. This relationship has been used to assess OPVs potential production at the site of interest. Similar correlation was made between the performances of a wave energy converter placed in the Adriatic Sea and the wave power matrix, to determine a suitable power data reference for the potential production of a wave energy converter to the Australian coast. Finally, the behavior of the microgrid was modeled. Different scenarios have been considered and the best one with optimal meteorological conditions enables lead to drastically decrease of the use of gas micro turbine resulting in lowest CO2 emissions. In fact, the consumption of natural gas has been summarized as follow: Season 1 (ST1): during this season the load is entirely fed by the renewable sources and by the battery, with consequent zeroing of the daily consumption of natural gas. Season 2(ST2): the battery is charged from 09:00am to 07:00pm with the exceeding power from the renewable sources. This configuration involves a daily natural gas consumption of 10.73 Sm3/d, which is equivalent to 987.16 Sm3/ ST2 (accounting for 92 days). Season 3(ST3): the battery is charged from 09:00am to 07:00pm with the exceeding power from the renewable sources. This configuration involves a daily natural gas consumption of 6.58 Sm3/d, which is equivalent to 1006.74 Sm3/ ST3 (accounting for 120 days). The avoided CO2 emissions are 2062 tons/year. This case study showed how the new renewable technologies, such as organic photovoltaics and wave energy converter, coupled with a long duration storage system, can be conveniently applied in sites with limited space for the decarbonization purpose of an offshore platform.
