I accidentally punctured a maybe 30% charged battery while attempting a display swap on my phone a couple years back. The thing started a nasty hissing sound and smoked like crazy. I was glad to live on ground level and was able to throw the thing onto concrete tiles in the backyard. Lithium battery energy density is no joke.
Battery fires are exotherm AFAIK and get very hot, flame retardants can probably only slow everything down.
Right I’m saying they work hella good
Not to mention if it was sitting around it was probably pretty full.
