Making a 12V soluble lead flow battery.

This video shows the construction and testing of a 12V soluble lead flow battery. This is the largest battery of its kind in any published research at the time of publishing, with an overall energy efficiency of 52.6%. The work was carried out by the cohort 3 of the EPSRC CDT for Energy Storage and its Applications at the University of Southampton.

Great explanation

[@dkjawahar-techexpt671]

Thank you for sharing the technical information and valuable inference 👍🙏thanks from Jawaharlal Bharath India

[@laurenceperkins7468]

If this design relies on material deposition on the plates, then doesn't that fail at decoupling capacity from reaction area? Especially where lead dioxide becomes highly resistive as its grain size becomes smaller? It might let you reduce incidental corrosion by using a less concentrated electrolyte, but the capacity is still going to be limited by plate surface area.

I wonder if your system might work better in a horizontal orientation

[@podarok_ua]

Interesting. Thank you for sharing.
Is it possible to add mechanical removal of leftovers after each cycle in order to improve cycling?

[@en2oh]

have you considered shunt current at all in your design? Those plates don't seem to have anything that could be seen as a modified flow path to reduce the shunt effects associated with all flow batteries - ie an electrically common cell electrolyte solution.

Hey, did you publish any research paper on this? any links? thanks.

Why you did not use oxidized graphite felts?
And use an external collector for pump the electrolyte.
I used sulfamic acid instead of MSA.

[@en2oh]

did it work with sulfamic acid? what were your aH v Voltage values?

[@Karabetter]

Question: Are the "cells" arranged electrically in series or parallel? It seems they are in series, yet the electrolyte is being circulated through all the cells in common. Wouldn't that mean 5 of the 6 cells would short out via the common electrolyte???
In contrast, a typical car battery is constructed so that each of the six cells has its own compartment. That's why each has a separate plug to check the water/electrolyte level.

[@98fraserej]

That is correct, the cells are arranged electrically in series and the same electrolyte is circulated through the each cell. In this battery, there may have been some charge transfer between the cells via the electrolyte (this is known as a shunt current), but the resistance of the electrolyte is high enough for it not to make a huge difference - especially when compared to some of the other problems with the battery. In an optimised cell, however, the resistance between cells via the electrolyte could be increased, for example by splitting the flow to each cell earlier so there is more electrolyte between each cell and hence a higher resistance and a lower shunt current.

are you using bipolar electrodes?

[@phoebemurray1359]

Who's the hottie with the long hair and beard?! 😍

[@oceanhouse8080]

considering that lead likes to form insoluble lead dioxide im fairly sure that this battery is mostly a self clogging failure.

[@Hclann1]

This is just one chemistry for potential flow batteries. They hold great promise and are cheap. The only downfall is size. The only potentially cheaper energy storage on the horizon is compressed air.

[@absolute___zero]

this battery design is unbelievable complex. Vanadium Redox Flow battery is much simpler and it has 50 year lifetime for every day charge/discharge cycle

[@ericlotze7724]

...but requires vanadium

[@Lawiah0]

"a 12V dc? bahaha

[@michaeld954]

Seems like and hho fuel cell

[@Hclann1]

It is a battery, refillable, not a energy source like fuel.

[@garethbaus5471]

The prencipal is similar, but this system has some advantages such as not needing to store hydrogen gas.

[@erik9549]

dude talk slower we might follow u then.

[@bobjones1131]

All of the voices in this video made me want to have a seizure !

[@tigertunertuner]

I will try to use lead-acid batteries at home, penetrate and circulate lead-acid by charging solar cells. Investment still costs a lot less. Ha ha ha. Tempted to play dangerous.

[@evilplaguedoctor5158]

if I'm understanding you correctly, that would not work, in a lead acid battery the active ions are in the solid electrodes, the electrolyte (the acid) is just a conduit for those ions to flow. increasing the amount of that acid won't increase the amount of charge you get.

[@laurenceperkins7468]

​@@evilplaguedoctor5158 No, the sulphur in the electrolyte plays an active part in the chemistry. That's why you can measure the charge level of a lead-acid battery by checking the concentration of the acid.
But he'd need to design the battery for such a usage. The plates will need to be thicker, and buildup of non-conductive lead-sulphate will be a significant problem. Just adding electrolyte tanks to a standard lead-acid battery would provide marginal gains at best.
