Electrolyte composition in all-vanadium liquid flow solar container battery
The electrolytes are novel, in that they contain additives of ammonium phosphate dibasic and magnesium chloride, which act to stabilize and improve the all-sulfate solution.. The all-vanadium redox flow battery is currently one of the most advanced battery systems because of the symmetric design of its positive and negative electrolyte solution. However, the thermal and chemical instabilities of V (V) species as well as the permeation problem have caused incompatibility. .
