Technical FAQs 4

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 S/Fe redox flow battery (RFB)?

An alkaline S/Fe redox flow battery with long cycle life over 3153 h. The capacity decay rate of S/Fe redox flow battery as low as 0.0166 % per cycle. The S/Fe redox flow battery (RFB) with abundant sulfide and iron as redox-active species shows promising applications for energy storage.

What is the capacity decay rate of S/Fe redox flow battery?

The capacity decay rate of S/Fe redox flow battery as low as 0.0166 % per cycle. The S/Fe redox flow battery (RFB) with abundant sulfide and iron as redox-active species shows promising applications for energy storage. It exhibits advantages including low cost, high safety, and flexible operation.

Are flow batteries suitable for large-scale energy storage?

Flow batteries have long been considered as a competitive candidate for large-scale energy storage owing to their advantages of high power density, long lifespan, and decoupling of energy density/power. However, high membrane and maintenance costs hinder their further development and application.
