Nataliya Roznyatovskaya et al. published a new paper on studies about the “power drop effect” in vanadium redox flow batteries. Free acid content in electrolytes for vanadium redox-flow batteries is a hardly accessible parameter in practice. If it can be roughly linked to electrolyte conductivity within the series of electrolytes with varied free acid content, such reversible or irreversible degradation phenomena as „power drop“ effect during discharge and thermally-induced aging of catholyte are shown to be dependent on electrolyte acidity. https://onlinelibrary.wiley.com/doi/full/10.1002/ente.202000445
