The electrolyte in vanadium flow batteries consists of an aqueous solution of vanadium ions in dilute sulfuric acid.. The electrolyte in vanadium flow batteries consists of an aqueous solution of vanadium ions in dilute sulfuric acid.. A flow battery is an electrochemical battery, which uses liquid electrolytes stored in two tanks as its active energy storage component. For charging and discharging, these are pumped through reaction cells, so-called stacks, where H+ ions pass through a selective membrane from one side to the. . ed network. Flow batteries (FB) store chemical energy and generate electricity by a redox reaction between vanadium ions dissolved in the e ectrolytes. Through the process of charging and discharging, the battery enables the conversion between electrical energy and chemical energy. . This paper presents a performance study of a VRFB battery operating with different charge and discharge currents and different electrolyte flow rates. The experiments were carried out using numerical models that model the mass transfer dynamics, the hydraulic system to calculate pressure losses and. . Commercial electrolyte for vanadium flow batteries is modi ed by dilution with fi sulfuric and phosphoric acid so that series of electrolytes with total vanadium, total sulfate, and phosphate concentrations in the range from 1.4 to 1.7 M, 3.8 to 4.7 M, and 0.05 to 0.1 M, respectively, are prepared.
