Lead-acid flow batteries offer a high energy density and cell voltage when compared to vanadium or zinc flow batteries. The cost of producing a lead-acid battery is much lower than most flow batteries as the electrolyte is easily obtained and no proton exchange membrane is required.
Very few analytical studies have been done on the soluble lead-acid flow battery. Experimental work was performed to validate simulation results. Gu, Nguyen, and White developed a mathematical model of a lead acid cell .
The electrolyte flow rate was 2.3–6.9 cm s −1 at a current density of 10 mA cm −2 . Analytical parameters used by Shah et al. closely match those used in this study. A good correlation was found between analytical and experimental work . Oury et al. studied a lead acid battery from a mathematical standpoint .
It can be seen clearly that the chemistry of this battery differs from the traditional lead-acid battery as Pb (II) is highly soluble in the methanesulfonic acid electrolyte and the electrode reactions do not involve insoluble Pb (II).
The biggest challenge in lead-acid flow battery technology is lead deposition on the electrodes. Overtime the process of deposition and removal degrades the electrode efficiency reducing the performance of the flow battery. Life cycle is very important to grid-scale energy storage.
Simulations are of a single cell lead-acid flow battery during a charge, discharge, and charge cycle. The simulations are 2D and include both anode and cathode electrodes and the fluid region between them. The electrodes are 10 cm long with an active area of 100 cm 2 and the electrode depth out of the plane is 10 cm.
