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.

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 is a zinc-bromine battery?

The leading potential application is stationary energy storage, either for the grid, or for domestic or stand-alone power systems. The aqueous electrolyte makes the system less prone to overheating and fire compared with lithium-ion battery systems. Zinc–bromine batteries can be split into two groups: flow batteries and non-flow batteries.

Are zinc bromine flow batteries better than lithium-ion batteries?

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 the second type of zinc flow battery, zinc metal is plated on the negative electrode on charge. The favorable electronic conductivity of zinc together with a very good interface means they have better power densities compared to other flow batteries.

How is zinc bromide stored in a battery?

A solution of zinc bromide is stored in two tanks. When the battery is charged or discharged, the solutions (electrolytes) are pumped through a reactor stack from one tank to the other. One tank is used to store the electrolyte for positive electrode reactions, and the other stores the negative. Energy densities range between 60 and 85 W·h/kg.
