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.
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.
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.
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).
Currently, the technology of the zinc-bromine batteries uses microprocessors to measure and control a range of operational parameters such as pH, temperature, electrolyte pressure pump, electrolyte levels and flow, state of charge, and stack and cell voltages.
Gao et al. demonstrated a zinc bromine static battery with a glass fibre membrane as the separator to control the self-discharge and improve the energy efficiency (Figure 10). This static battery was achieved by using tetrapropylammonium bromide (TPABr) as the complexing agent.
