Going back 30-odd years, I looked at an Uher portable real-to-reel tape
recorder for an acqauintance.  The battery (a NiCad) would no longer
store a charge.  I removed the battery's seal strip and looked into
the cells through the rubber vents.  The cells had dried out, and
crystals of electrolyte were visible.  I took a hypodermic syringe
and filled the cells with water.  When I tested the battery, its
capacity was about 105% of nominal.

So the water in the electrolyte had been dissociated into hydrogen and
oxygen as a result of the charging regime he had applied.

Whether that has any relevance to today's battery technologies, I
don't know.  (I'm sure water is not involved, but whether any other
constituent can be similarly destroyed...)

All batteries gradually lose their capacity over time and use.
