Mark-T said:I was talking to someone about batteries the other day.
He said when you bring certain metals together, the
potential appears 'naturally', i.e. merely by the action
of sandwiching them. I answered that's impossible,
it would be free energy, entropy contradicts it. It has
to be charged, after bringing them into proximity.
Assuming I am correct - that raises the question of
how the manufacturer charges them up in the first place,
for the non-rechargeable types.
Conversion of the raw metal ores into metal. Takes a *lot* of energy.
Most metals (gold is an exception) don't like to remain metal - in our
wet, oxygen atmosphere, they will revert to the ore phase.
e.g. alkaline batteries (what does that mean anyway?)
IIRC, potassium hydroxide (alkaline base) as the electrolyte in
alkaline batteries.
