I was going to just throw it away. What if it was sorted as recyclable waste at the garbage sorting place?
Maybe someone will dispose of it well.
It may depend on your location but generally speaking, if you throw something away as bulk waste, it is not sorted through at all, unless the collector spots something that cannot be put in the landfill then it is left and not picked up at all.
If you want to recycle it, make sure Google can approximate your location in a browser then search "battery recycling near me", or without location awareness for the browser, enter a local city name in the search, the among the search hits, check which ones do bare Li-Ion.
Personally, I have a metal ammo box and I put old batteries into it (making sure they can't short out against each other or the box), so I can take several batteries to a recycler at once instead of a separate trip for each. I keep the ammo box in the garage on a concrete floor so if it were to ever achieve thermal runaway, it is self contained and the heat won't do harm to anything else.
