What other materials? And like Darkgenerals said, the amount of USED lithium in an R/C battery isn't anywhere near enough to make it worth the effort needed to get it out.

BestBuy just gives tree huggers a place to feel good about themselves. In reality the "battery recycling" bin probably just gets emptied into the garbage dumpster with the rest of the trash at the end of the day

Only battery I know of with enough value to recycle is the one likely in you car. That's because it's full of lead, and a lot of it..that's why they PAY you for it.

Like I said before, toss it in the trash and hope the garbage truck turns the corner before you see smoke
