As a battery discharges,
the electrolyte displaces less space. The larger the volume of electrolyte,
the more vacuum is created.
Thanks for correcting me on that Stan. For some
reason I interpreted writings here as meaning the water floated atop the acid
in a seperate layer. Good to know my first notion was correct after
all.
I already understood that the oil filled pod
stopped any water pressure as in your baloon analogy below. Learned that a
long time ago. Drop a barrel totally filled with oil and no air into the ocean
and it will sink to the titanic with no water pressure
affecting it. Water-uncompressable.
Oil-uncompressable. Ergo--no water pressure effect on totally oil filled
container.
But what I do not understand and need help on is
this....
How EXACTLY does that vacuum that Vance
and others mentioned form in a battery pod if you are using hydrocaps? If
the hydrocaps are having to rob the ambient air in the pod
for oxygen to create water because there is not enough oxygen from
the original seperation of the water
into hydrogen and oxygen for them to totally recombine again, then
where did that originally seperated oxygen go and whereever it went, what
is it doing?
I believe someone mentioned it somehow
formed an oxide? But they only briefly mentioned it and did not
elaborate. Is this correct? If it is, then what happens to make the
oxygen bond and get trapped making an oxide so that it can't recombine with
the hydrogen? Does ALL of the oxygen that was seperated go into making an
oxide, or is any of it left to recombine with the hydrogen? I have to
know this before I can understand why the vacuum forms.
Thanks Stan.
Kindest Regards,
Bill Akins.

Hang in there Bill, you were right before...
The water
and the acid are mixed... They do not form separate layers in the
battery. When I refer to the water in the battery, I am referring to
dilute sulfuric acid. Water mixes with the acid and dilutes
it.
In an oil-filled lead acid battery, the oil floats on the dilute
acid....
This is not a complex concept. Take a balloon and fill
it with air. Take it 10 feet underwater. The balloon will shrink
because the water pressure compresses the air inside until the air pressure
inside the balloon equals the water pressure outside. Boyle's law,
pressure and volume of a gas: since the pressure is more, the volume
is less. Now take an identical balloon and fill it with water.
Submerge it 100 feet underwater and it doesn't get any smaller because the
increased pressure doesn't compress the water.
Now, instead of a
balloon, think of a battery box...filled with lead, acid, and oil, all
non-compressible materials...
