I'm not chemist, but I would suspect that batteries go "bad" for lots of
different reasons. I know a few tidbits here and there, but it seems in
general chemicalreactions are not perfectly reversable because of unwanted
byproducts and side effects. I don't believe this can ever be completely
eliminated, only
reduced. Molecules can always arrange themselves lots of different
ways...good and bad.
Where is a good source for literature about such things battery related?
(especially Lifepo4 related)
You'd think this was a highly important subject.

Reason why cells go broken today is the liquid electrolyte and passivation
layers it needs. Function of time and temperature and voltage.
In theory LFP cell with solid, e.g. cellulose, electrolyte can provide
millions of cycles. Cathode already is stable enough to support that but
for anode we need some more stable 3D steuctures. Doable and plenty of good
ideas to be tested.
