I don't know about the battery you're referencing but as far as phones go: I once cooked a Li battery from a Galaxy S5 under a thermostream at 200C (totally not by accident guys!) and it outgassed a lot, but there was no signs of fire. The battery was certainly warped and distended, and no doubt it got hot! Further, I've seen videos of people piercing phone batteries, and it outgasses, but there was no fire. Not saying it's impossible, but at least with phones, it's less likely.

Did it still hold a charge after you were done?

  I confess I didn't try it. The whole casing had ruptured and was warped / distended. It wouldn't have even been close to fitting back in the phone. Also, passing current through it was the furthest thing from my mind. I assure you, it's not because I was embarrassed by my screwup and trying to clean up my mess as quickly as possible (plus feeling a little loopy from being gassed out).

    I hope you went to a hospital to get checked out after that. Some of the gases from cooking li-ion batteries are poisonous, and can cause long-term damage. Honestly, if you see a li-ion battery on fire, probably the best thing to do is to run. Throw it somewhere not-very-flammable if convenient, but get the heck out of there. And hold your breath.

      I didn't go to the hospital. It was in a large well-ventilated room, so it was bad, but not awful (mostly could just smell something bad). And it never actually caught fire. I did however throw it in a chamber we had fashioned for tests that might explode a battery (which this one was not supposed to be). One of my co-workers got the worst of it, and I think he ended up calling out sick the next day. I felt really bad about that. *edit: Just wanted to add that your advice is still sound. I strongly advise against inhaling that stuff. Better yet, don't cook them, and don't deviate from your procedure just because someone came and asked you for help at precisely that moment.
