Silicon Salt Battery

[jeanna]

Gary,
Is this a car battery you refer to as optima battery?

The idea to switch seems like one to pursue. but first, I want to address what is happening with the lead.

If this alkalinization of the acid battery produces better electricity and can be used after the acid battery has lost its usefulness, then this would double the life of one battery and one amount of lead etc.

However, one guy in his description was dumping the liquid out of his almost dead lead-acid battery in order to change its chemistry to alkaline with the addition of alum.

So, it may be a dreadful thing to do to your backyard (I won't even go on from there  , ) and may not justify its use at all.

This is why I am asking for understanding of the chemistry.

Is there lead in the acid liquid of an almost used up lead acid battery?

I remember the liquid turns to water at some part of its cycle. Is it when it is flat?

I will be checking it out later. I just realized I did not make my question very clear.

Thank you,

jeanna

Yes the one I was talking about is in my car .    .      http://www.optimabatteries.com/optima_products/

good  questions
I am not  going to  try  changing the electrolyte in  a battery .
I  remember  something about lead  leaching into  the  soil  from lead based  paint .     if livestock  eat   grass growing over  a disposal  site they can ingest  dangerous amounts of lead . 

I  don't think it will be easy  to get  details on exact chemistry of lead acid batterys .  The  chemistry is what makes them  better or worse than their  competition .

OK folks, this is it for me.

wiki says

). In the discharged state both electrodes turn into lead(II) sulfate (PbSO4) and the electrolyte loses its dissolved sulphuric acid and becomes primarily water

In the next paragraph it says that the lead paste eventually drops into the liquid part of the battery and builds up a lead sludge from the bottom.

So, for me this is way too dirty a technology.

Yes, Gary lead causes   nerve damage to all and brain damage to children whose brains are rapidly growing.

NO THANK YOU ON THIS ONE!

I though this was pretty interesting.  Pretty dam expensive though.  If you electrolyze water with a solar panel and create your own hydrogen, the energy would be dirt cheap.  Not sure the about the lifetime of the pack though, or if you could even replenish the cell on your own.

Another reference to the salt battery

"Their Magnetic Air Car uses a silicon salt battery having 30% more mass power than a lead acid storage battery, and it can completely charge in one hour. The battery is also environmentally friendly: it’s 95% recyclable, and it can be used in almost extreme conditions: from -40 to +50 degrees Celsius. I say almost, because the temperatures inside a car during summer exceed 50 degrees. "
