4 FAQs about Sulfuric acid consumption of vanadium redox flow battery

Which electrolytes are supported in a vanadium redox flow battery (VRFB)?

A comparison study was conducted for various supporting electrolytes of sulfuric acid (H 2 SO 4), hydrochloric acid (HCl), and mixed acids (H 2 SO 4 + HCl) in a vanadium redox flow battery (VRFB).

What are the advantages of vanadium redox batteries?

Vanadium redox batteries have the unique advantage of using only one electrolyte, which dissolves V2O5 in H2SO4, to provide the potential redox reaction and the reversed reaction, allowing the battery to be circularly charged and discharged. This feature brings a wide range of applications, including the Wind Energy Market.

Are vanadium redox batteries suitable for electric vehicles?

Vanadium redox batteries are suitable for electric vehicle power supply due to their huge charge acceptance ability to adapt to fast high-current charging and high current depth of discharge. This makes them a viable solution for electric vehicles to help address vehicle emissions air pollution problems.

How does sulfuric acid affect a VRB battery?

Sulfuric acid solutions, the electrolyte used in current VRBs, can only hold a certain number of vanadium ions before they become oversaturated, and they only allow the battery to work effectively in a small temperature window.
