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.
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. Despite these advantages, challenges such as the polybromide ion shuttle effect, self-discharge, and zinc anode instability hinder their widespread applications.
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.
In this context, aqueous rechargeable zinc-based batteries (AZBs), which employ metallic zinc as the anode, have garnered considerable attention as promising candidates for large-scale energy storage applications.
