A scaled-up soluble lead-acid flow battery has been demonstrated, operating both as a single cell and as a bipolar, two-cell stack. Using short charge times (900 s at ≤20 mA cm −2) the battery successfully runs for numerous charge/discharge cycles.
MSA is a well understood acid that has become very popular in electroplating applications. Because of this, its high conductivity, high metal salt solubility and overall safer nature, it is clear that MSA is the acid of choice for the soluble lead flow battery. 3.4. Electrolyte density and viscosity
A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
Conclusions and future work The soluble lead flow battery offers some advantages over other chemistries due to the single active species, Pb 2+.
Following a large number of charge/discharge cycles, a soluble lead-acid flow battery could fail due to cell shorting caused by the growth of lead and lead dioxide deposition the negative and positive electrode, respectively.

The lead–acid cell can be demonstrated using sheet lead plates for the two electrodes. However, such a construction produces only around one ampere for roughly postcard-sized plates, and for only a few minutes. Gaston Planté found a way to provide a much larger effective surface area. In Planté''s design, the positive and negative plates were formed of two spirals o…
