4 FAQs about Croatia New Energy All-vanadium Liquid Flow Battery Electrolyte Pump

Are chloride ions an electrolyte additive for high performance vanadium redox flow batteries?

Chloride ions as an electrolyte additive for high performance vanadium redox flow batteries Appl. Energy, 289(2021), 10.1016/j.apenergy.2021.116690 Google Scholar M.Skyllas-Kazacos, L.Goh Modeling of vanadium ion diffusion across the ion exchange membrane in the vanadium redox battery

What is a commercial vanadium electrolyte?

Currently, commercial vanadium electrolytes are primarily H 2 SO 4 (2.5–3.5 mol/L) solutions dissolving 1.5–2 mol/L vanadium, with energy densities typically around 25 Wh/L, significantly lower than Zn mixed flow batteries, which can achieve energy densities up to 70 Wh/L [10, 20].

What electrolytes are in a vanadium battery?

Besides sulfuric acid, there are other supporting electrolytes in the vanadium electrolyte. The electrolyte of vanadium batteries usually consists of sulfuric acid as the main component. However, to enhance the conductivity and stability of the electrolyte, other supporting electrolytes may be added, such as ammonium salts and chlorides.
