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.
Lead is relatively low cost, readily available and recyclable within existing commercial supply chains, while methanesulfonic acid is less aggressive to component materials than sulfuric acid or strong alkaline electrolytes (for example KOH) typically found in other flow batteries.
The saturation solubility of the lead methanesulfonate salt, Pb (CH 3 SO 3) 2, in water is 2.6 M, which is a sufficiently high storage capacity limit for battery operation. The solubility of lead methanesulfonate falls with increasing MSA concentration, from approximately 2.2 M at 0.9 M MSA, to almost zero near 8 M MSA.
Which acid is best for soluble lead flow battery?
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
Is slfb a soluble-lead flow battery?
Scalability of the system is considered, involving a description of the 1000 cm 2 flow cell stack only available as a DTI technical report. The soluble-lead flow battery (SLFB) utilises methanesulfonic acid, an electrolyte in which Pb (II) ions are highly soluble.
What is a novel flow battery?
A novel flow battery: a lead acid battery based on an electrolyte with soluble lead (II) Part IV. The influence of additives J. Collins, G. Kear, X. Li, C.T.J. Low, D. Pletcher, R. Tangirala, et al. A novel flow battery: a lead acid battery based on an electrolyte with soluble lead (II) Part VIII. The cycling of a 10 cm × 10 cm flow cell
The supporting electrolyte and operational principle of the standard lead-acid battery (LAB) are fundamentally different to the SLFB. The simplest form of the LAB is known as a flooded cell, which consists of solid lead (negative) and lead dioxide (positive) electrodes immersed in a static sulfuric acid solution.
