This paper introduces the working principle and main components of zinc bromine flow battery, makes analysis on their technical features and the development process of zinc bromine battery was reviewed, and emphasizes on the three main components of zinc bromine battery, and summarizes the materials and applications of electrolyte, membrane and electrode.
Zinc bromine flow batteries or Zinc bromine redux flow batteries (ZBFBs or ZBFRBs) are a type of rechargeable electrochemical energy storage system that relies on the redox reactions between zinc and bromine. Like all flow batteries, ZFBs are unique in that the electrolytes are not solid-state that store energy in metals.
While zinc bromine flow batteries offer a plethora of benefits, they do come with certain challenges. These include lower energy density compared to lithium-ion batteries, lower round-trip efficiency, and the need for periodic full discharges to prevent the formation of zinc dendrites, which could puncture the separator.
Zinc-bromine flow batteries (ZBFBs) offer great potential for large-scale energy storage owing to the inherent high energy density and low cost. However, practical applications of this technology are hindered by low power density and short cycle life, mainly due to large polarization and non-uniform zinc deposition.
Lee et al. demonstrated a non-flow zinc bromine battery without a membrane. The nitrogen (N)-doped microporous graphene felt (NGF) was used as the positive electrode (Figure 11A,B).
Static non-flow zinc–bromine batteries are rechargeable batteries that do not require flowing electrolytes and therefore do not need a complex flow system as shown in Fig. 1 a. Compared to current alternatives, this makes them more straightforward and more cost-effective, with lower maintenance requirements.
Zinc–bromine rechargeable batteries are a promising candidate for stationary energy storage applications due to their non-flammable electrolyte, high cycle life, high energy density and low material cost. Different structures of ZBRBs have been proposed and developed over time, from static (non-flow) to flowing electrolytes.

Flow battery technologies may be applied to provide modular, configurable, and scalable energy storage. Flow battery energy storage systems (ESSs) can support renewable energy generation and increase energy efficiency. Applications may include providing power to remote, off-grid locations (e.g., military sites or remote communities).
Flow battery developers must balance meeting current market needs while trying to develop longer duration systems because most of their income will come from the shorter discharge durations. Currently, adding additional energy capacity just adds to the cost of the system.
The principle of the flow battery system was first proposed by L. H. Thaller of the National Aeronautics and Space Administration in 1974, focusing on the Fe/Cr system until 1984.
The flow batteries in the system contain a zinc-bromine complex that, depending on state of charge, presents varying chemical safety concerns. Under normal operating conditions, the liquid is contained within the flow battery tank.

Notable exceptions include the models developed by Shah et al. 24 and by Li and Hikihara 25 for the all-vanadium system and by Scamman et al. 3 for the bromide–polysulphide battery. There are no models, as far as the authors are aware, of the soluble lead-acid flow battery, even in the simplest cases.
Self-discharge was also observed in the case of the soluble lead-acid flow battery when it was left open-circuit for a long time period. To test the self-discharge characteristic of a soluble lead-acid flow battery, a series of charge/discharge cycles were performed.
There is little work regarding the flow rate in the soluble lead flow battery. Understanding the relationship between flow rate and cell performance is important, as this could minimise the pump power whilst maintaining good electrochemical performance.
Following a large number of charge/discharge cycles, a soluble lead-acid flow battery could fail due to cell shorting caused by the growth of lead and lead dioxide deposition the negative and positive electrode, respectively.
Conclusions 1. The electrochemistries of the soluble lead-acid flow battery and the static lead-acid battery are distinctly different; in the soluble lead acid battery lead is highly soluble in the electrolyte of methanesulfonic acid, while lead is a solid paste in the static lead-acid battery.
The flow battery was found to have a better charge efficiency than the static one, but the cells were found to have comparable energy efficiencies. The self-discharge characteristics of the soluble lead-acid battery were also measured and compared to reported values for a commercial static battery.
