Interestingly, the Lithium content is the, in theory, valuable part of
it. There's not actually much Li in a typical Li-Ion rechargeable
battery (much less than a Li metal primary cell), but my understanding
is that it's enough to have people interested considering that we're
already basically consuming the world's Lithium supply just about as
fast as we can economically mine and refine it. However, that may
account for the apparently low recyleable content of a given battery.
By mass and volume, it's mostly electrodes, which are common metals, and
paper separator which is worthless.
I would imagine that, as "dead" Li-Ion cells become more available and
demand presumably continues to rise (absent a better battery tech),
folks will get more serious about recycling the electrolyte.
