I believe they experience all of those. But yes, there are many secondary uses, especially in situations where high energy density isn't required.

After the last economically viable use for electricity storage, however, there has to be an economic incentive to actually recycle the raw materials. Presumably this is when value of the raw materials exceeds the cost of their reclamation.

> I believe they experience all of those.

Hmm...would that explain the CPU performance loss of an aging cell phone battery? Lower discharge efficiency = less power available for the CPU = CPU throttles itself to lower power usage?

That is exactly what happened, yes. Without the throttling, the battery can't deliver peak power, and the device crashes.
