What is a zinc bromine flow battery?
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.
When were zinc-bromine flow batteries first patented?
Zinc-based batteries aren’t a new invention—researchers at Exxon patented zinc-bromine flow batteries in the 1970s—but Eos has developed and altered the technology over the last decade. Instead, the primary ingredient is zinc, which ranks as the fourth most produced metal in the world.
Are zinc-bromine flow batteries suitable for large-scale energy storage?
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.
What is the main challenge of zinc-bromine flow batteries?
One of the main challenges is to increase this storage beyond 4h in order to decrease the kWh cost. The most common and more mature technology is the zinc-bromine flow battery which uses bromine, complexed bromine, or HBr3 as the catholyte active material.
What is a non-flow electrolyte in a zinc–bromine battery?
In the early stage of zinc–bromine batteries, electrodes were immersed in a non-flowing solution of zinc–bromide that was developed as a flowing electrolyte over time. Both the zinc–bromine static (non-flow) system and the flow system share the same electrochemistry, albeit with different features and limitations.
What are static non-flow zinc–bromine batteries?
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.
