Technical FAQs 4

What is a redox-flow battery?

An aqueous, polymer-based redox-flow battery using non-corrosive, safe, and low-cost materials. Nature 527, 78–81 (2015).

What is redox flow battery (RFB)?

Inspired by the advancements in proton exchange membrane fuel cells and direct methanol fuel cells, ongoing research primarily concentrates on Redox Flow Battery (RFB) systems. The primary objective is to substitute costly Nafion membranes, which contribute approximately 40% to the total cell stack cost.

How does a redox flow cell work?

The redox flow cell thus stores energy in the solutions, so that the capacity of the system is determined by the size of the electrolyte tanks, while the system power is determined by the size of the cell stacks. The redox flow cell is therefore more like a rechargeable fuel cell than a battery.

Are redox flow batteries a viable solution for large-scale energy storage?

Redox flow batteries (RFBs) have emerged as a promising solution for large-scale energy storage due to their inherent advantages, including modularity, scalability, and the decoupling of energy capacity from power output. These attributes make RFBs particularly well-suited for addressing the challenges of fluctuating renewable energy sources.
