Almost certainly a larger percentage than you'd imagine. LI ion batteries are composed mostly of Nickel and Steel. Both of which are highly recyclable. The fact that they are also able to pull out the lithium is really pretty impressive. The structure of a LI ion battery is essentially a steel case with a metal foil (iron or nickel) coated with a lithium/cobalt/silicon/carbon/phosphorous powder.
