6 FAQs about [Greek chromium flow battery]

What is iron chromium redox flow battery?

Iron-chromium redox flow battery was invented by Dr. Larry Thaller's group in NASA more than 45 years ago. The unique advantages for this system are the abundance of Fe and Cr resources on earth and its low energy storage cost. Even for a mixed Fe/Cr system, the electrolyte cost is still less than 10$/kWh.

How to improve the performance of iron chromium flow battery (icfb)?

Iron–chromium flow battery (ICFB) is one of the most promising technologies for energy storage systems, while the parasitic hydrogen evolution reaction (HER) during the negative process remains a critical issue for the long-term operation. To solve this issue, In³⁺ is firstly used as the additive to improve the stability and performance of ICFB.

Which electrolyte is used for iron chromium ow battery?

performance of the electrolyte with indium ion for iron–chromium ow battery. Electrochimica Acta 368: 137524. 52 Ahn, Y., Moon, J., Park, S.E. et al. (2021).

Why do we need a flow battery?

The flow battery can provide important help to realize the transformation of the traditional fossil energy structure to the new energy structure, which is characterized by separating the positive and negative electrolytes and circulating them respectively to realize the mutual conversion of electric energy and chemical energy [, , ].

How is a flow battery assembled?

The flow battery was assembled with a piece of Nafion 212 membrane, two pieces of CF (3 cm × 3 cm × 0.3 mm) with a compression ratio of 50% and two graphite plates (Fig. S1). The anolyte (30 mL) and catholyte (30 mL) were stored in airtight tanks and pumped into the flow battery at 50–60 mL/min.

How do divalent chromium ions react?

As reactants, divalent chromium ions are replenished at the inlet branches. Consequently, the concentration of these ions decreases gradually from the inlet to the outlet branches, illustrating the consumption of the ions as they react along the flow path.
