I toss mine in the trash and hope he makes it to the dump before she blows up..Ha!

That said, I've had success with the salt water bath. It discharged a cell from ~3V down to a few tenths of a volt in 4 weeks.

I've read this too, my theory is that it probably used to be true on older packs but given the higher C ratings of today's batteries, I would imagine the tabs are much more robust. Of course, it's only a theory.

If you're draining the cells below 3V or so, make sure that you don't ever accidentally attempt to recharge the pack!
Honestly, once the cells are discharged to 3V or thereabouts, there is very little electrical energy left in the pack, and I'm unconvinced that it's necessary to drain it any further.

You have to remember most packs are not single cell. A 3s or 4s pack would still have 9 - 12 volts of energy and I'm guessing wouldn't have any issue starting a fire.

It's the reason most recycling places wont pay you for your old lipo batteries.

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

The story is somewhat different once we start talking about recycling millions of 50kWh packs from electric cars.

There is a trivial amount of lithium carbonate in a hobby battery. The stuff is only worth about $3/lb, and you're talking about ounces at most in the typical pack.

Not trying to put you on the spot, I work for a scrap yard and $3/lb materiel is getting into copper prices, and we don't deal in lithium batteries because the value is so small for the head ache they cause.

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.

My main concern with scrap lithium batteries is the risk of fire, and once again, simply discharging them down to 0% SOC (<3V/cell) largely takes care of that concern.

Yeah, that's for clean "virgin" material. It has some significant value, but there isn't much in a small battery. You've got maybe a couple dimes worth of the stuff in a hobby pack (or power tool, or cell phone), and so by the time you look at the cost of the recycling process, it's a fool's errand. The situation is totally different from the value contained in a scrap lead-acid battery. There also isn't the toxicity concern that one had with NiCad batteries (which we really didn't want going into landfills).
