I accidentally made a small puncture in an old li-ion battery while replacing it in my phone (it's stuck on pretty tightly with adhesive). A couple of sparks, but no flames. It has been safely disposed of.
The damaged battery emitted a sweet smell after it was punctured, so I immediately went outside to complete the removal. I feel fine and everything, I just want to be sure; is there any potential harm that could come from briefly inhaling the fumes?

Not that I'm aware of. I've done the same from time to time. Acute exposure has never been problematic. What's inside is some kind of organic solvent that's proprietary. Knowing that and what we know about toxicity of organic solvents, your body may accumulate these over time if you have repeated exposure resulting in illness years down the line. If this is a one time thing, don't sweat it. Just don't make it a habit.
