Technical FAQs 4

What are the different types of flow batteries?

Some of the types of flow batteries include: Vanadium redox flow battery (VRFB) – is currently the most commercialized and technologically mature flow battery technology. All iron flow battery – All-iron flow batteries are divided into acidic and alkaline systems, and acidic all-iron flow batteries are relatively mature in commercial development.

Are flow batteries based on electrolyte chemistry?

There are several variations of flow batteries based on electrolyte chemistry. The electroactive materials are redox pairs, i.e. chemical compounds that can reversibly undergo reduction and oxidation.

What are the characteristics and benefits of flow batteries?

The major characteristic and benefit flow batteries is the decoupling by design of power and energy. Power is determined by the size and number of cells, energy by the amount of electrolyte. Their low energy density makes flow batteries unsuited for mobile or residential applications, but attractive on industrial and utility scale.

What is the difference between a battery and a flow battery?

Batteries and flow batteries/fuel cells differ in two main aspects. First, in a battery, the electro-active materials are stored internally, and the electrodes at which the energy conversion reactions occur are themselves part of the electrochemical fuel. The characteristics of the negative and positive electrodes determine both the power density
