Understand the architecture and specific zinc-bromine chemistry that enables safe, long-lasting, and highly scalable grid energy storage.
In contrast to conventional aqueous batteries constrained by sluggish ion diffusion through solid-state materials, ZBBs leverage the liquid-phase redox activity of bromine to achieve
Flow batteries are promising for renewable energy storage due to their safety and scalability. Zinc/bromine flow batteries (Zn/Br) are popular due to their high energy densities and
Zinc‐bromine flow batteries are a type of rechargeable battery that uses zinc and bromine in the electrolytes to store and release electrical energy. The relatively high energy density and long
These features make zinc-bromine batteries unsuitable for many mobile applications (that typically require high charge/discharge rates and low weight), but suitable for stationary energy storage

A zinc-bromine battery is a rechargeable battery system that uses the reaction between zinc metal and bromine to produce electric current, with an electrolyte composed of an aqueous solution of zinc bromide. Zinc has long been used as the negative electrode of primary cells. It is a widely available, relatively inexpensive metal. It is rather stable in contact with neutral and alkaline aqueous solutions. For this reason, it is used today in zinc–carbon and alkaline primaries.
Aqueous zinc-bromine batteries (AZBBs) gain considerable attention as a next-generation energy storage technology due to their high energy density, cost-effectiveness and intrinsic safety.
Here, we discuss the device configurations, working mechanisms and performance evaluation of ZBRBs. Both non-flow (static) and flow-type cells are highlighted in detail in this review.
Like all flow batteries, ZFBs are unique in that the electrolytes are not solid-state that store energy in metals. They store energy in electrolyte liquids held in two tanks one containing a
Known for their high energy density and scalability, these batteries are ideal for large-scale energy storage applications, such as stabilizing power grids and storing renewable energy.
