6 FAQs about [Working principle of zinc-bromine flow battery]

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.

How do no-membrane zinc flow batteries work?

In no-membrane zinc flow batteries (NMZFBs) or iterations of the ZBFB that does not use a membrane to separate the positive and negative electrolytes, the electrolytes are separated by a porous spacer that allows ions to pass through but prevents the two electrolytes from mixing.

What is a zinc flow battery?

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 does a znbr battery work?

In a ZnBr battery, two aqueous electrolytes act as the electrodes of the battery and store charge. The electrolyte solutions contain the reactive components, zinc and bromine, and as these solutions flow through the battery's cells, reversible electrochemical reactions occur, and energy is either charged to the battery or discharged.

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.

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.
