Technical FAQs 4

What is a flow battery?

Flow batteries are a type of electrochemical ES, which consists of two chemical components dissolved in liquid separated by a membrane. Charging and discharging of batteries occur by ion transferring from one component to another component through the membrane. The biggest advantages of flow batteries are the capability of pack in large volumes.

How much discharge can a flow battery have?

Considering the distribution of volumes of typical flow batteries between volume in stacks and volume in tanks, then most often the potential volume for discharge is far less than 1%. Flow batteries may vary inside their own technology community but usually they work in ambient temperature ranges.

How does a flow battery differ from a conventional battery?

In contrast with conventional batteries, flow batteries store energy in the electrolyte solutions. Therefore, the power and energy ratings are independent, the storage capacity being determined by the quantity of electrolyte used and the power rating determined by the active area of the cell stack.

How long does a flow battery last?

Flow batteries can release energy continuously at a high rate of discharge for up to 10 h. Three different electrolytes form the basis of existing designs of flow batteries currently in demonstration or in large-scale project development.
