Just a word of warning, I had a pair of 18650s go nuclear last week after a manufacturing defect led to a partial buckling of the cylinder as I was snugging up a screw-post. When these things go they go big-time. I'm not swearing them off for life, but they're not the type of thing that would be taken lightly... Never put these in a junk drawer with bits of metal. It's like a white hot, floating estees model rocket engine if anything goes wrong.

Yes, any spare Li-Ion cell should be stored in a flameproof metal, insulated container. That goes for your old cell phones w/battery and cordless tools too. You are playing with fire if you don't.
