Soluble lead redox flow battery (SLRFB) is an allied technology of lead-acid batteries which uses Pb 2+ ions dissolved in methanesulphonic acid electrolyte. During SLRFB charging, Pb 2+ ions oxidize to Pb 4+ ions as PbO 2 at its cathode and concomitantly reduce to metallic Pb at its anode.
Moreover, the conventional lead-acid battery technology over 150 years old has a firmly established worldwide production infrastructure. SLRFBs, an allied technology with reports emerging that spent lead-acid batteries can be utilised to make electrolytes to develop SLRFBs, offer a good supply chain of raw materials.
The mechanism of electrodeposition of lead from acids and alkaline electrolytes has already been discussed in the literature. 51 Two possible mechanisms exist for the electrochemical reduction of Pb 2+ ions to Pb in acidic media. These are as follows: (ii) A two-step 1-electron transfer reaction.
SLRFBs, an allied technology with reports emerging that spent lead-acid batteries can be utilised to make electrolytes to develop SLRFBs, offer a good supply chain of raw materials. In addition to its similarity to the lead-acid battery industry, lead and lead dioxide deposition are known in the electroplating and water treatment industries.
It is observed that the ratio of O : Pb are 1.52, 1.72 and 1.53 for PbO x in these three electrolytes respectively. 71 It is also reported that during cycling of the electrodes the oxygen content on PbO x is further reduced.
Oxygen evolution reaction: OER is relatively slow due to low overpotential compared to lead-acid batteries. Additives like NaF are found to decrease OER. However, NaF gets deposited as PbF 2 at higher concentrations and during long hours of operations.

These lead-acid batteries usually contain an electrolyte that can freely move inside the battery encasement. When it is being charged, its battery acid and lead plates usually react to store electricity. Thus, they are meant to be placed upright so that the electrolyte will not leak out of the caps on top. Also, you must check the levels ...
The electrical energy produced by a discharging lead-acid battery can be attributed to the energy released when the strong chemical bonds of water molecules are formed from H+ ions of the acid O2- ions of PbO2. Conversely, during charging, the battery acts as a water-splitting device.
