Silicon Salt Battery

[Thaelin]

Hi all:   
   Starting to see reference to this new type of battery but can find no real info on it.
I am converting an E-Bike and this extra punch would help out on distance. Thanks

This is very interesting. I wonder what the chemistry is.

Some links promised to tell, but I didn't see any chemistry info.

This sodium aluminate should be easy to get from clay which is mostly just that sodium/aluminum/silicates.

Do you have the info to publish here to make this easy, Thaelin?

thank you,

   Sadly no I have nothing to go on at the moment. I did hear that an e-bike company
in germany ships it with this type of battery. All the battery companies here in the
US have no info on them or heard of them.

  Maybe Stephan has a lead???

OK I will study up a little to refresh.

I am pretty sure the lead acid battery has one kind of lead in a paste squished into a grid made of lead of another type and the sulphuric acid makes the reaction. I have never seen the explanation that "sticks".

This question gives me good reason to really look for it.

So, then for now conceptually at least, I suppose that with these 2 kinds of lead still in place, the Na/Al//Si in this alkaline environment will react with the lead and give it new life? maybe as some reports said, more peppy.

I'll have a look.

Maybe someone else can help?

A paste is not always used .

I remember around  15 or 20 years ago  they switched  the  stuff they add to the plates .   at  the time thecalled batterys with the   new  chemistry   "low maintanance "   

Another   variation is  the  optima  battery .   It  has  its  plates in the form  of a  mats  of lead  threads .
the  mats are  sandwiched   between  layers of  fiberglass ......the  whole thing is  rolled up into  a  cylinder  .  Because   the  plates are  tightly  rolled between  layers of fiberglass   the plates themselves need little or no mechanical  strength  so the  chemistry  can be optimised   for  electrical   properties rather than a combination of  electrical and mechanical   properties .
Optima  batterys  cost   around  3 times more than  regular batterys  but  are said to last  4 times longer .   Mine is  4 years old  and  seems  to be as good as new .

There  is  only one  small  vent  on my  optima  and no place where water could be added .
