A novel flow battery: A lead acid battery based on an electrolyte with soluble lead(II) - Part I. Preliminary studies

This series of papers will describe the chemistry, electrochemistry and performance of a flow battery with no separator and a single electrolyte, lead(II) in methanesulfonic acid. Voltammetry at rotating disc electrodes is used to define the conditions for the high rate deposition and dissolution of lead and lead dioxide in aqueous methanesulfonic acid. The determination of lead methanesulfonate solubility and solution conductivity as a function of lead methanesulfonate and methanesulfonic acid concentrations was carried out in order to aid the selection of the electrolyte for the battery.
