It's not the lithium that's burning - it's first the electrolyte, typically ethylene carbonate, which decomposes the cathode - a process that releases oxygen, which in turn fuels the fire.
There's actually very little lithium by weight in li-ion batteries.
That is not true. Please don't spread misinformation that could lead to deaths or people losing everything they own.
You can put out a Lithium battery fire with a class-D fire extinguisher. If you don't have one available, you can isolate the burning battery by surrounding it with sand or other inert, dry substances to keep it from spreading until the fire department arrives with proper equipment to dispose of or extinguish it.
You forgot having a fume hood, or halon foam system. Or just a silver heat resistant suit and SCBA. Please don't hold back on the pedantry and "you can"s. People might miss these valuable options and not know they can just coexist with the lithium fire right next door!
Instead of being upset and lashing out when someone corrects you and offers important advice that can save lives, you can just say "Thank you for the information." - or even say nothing at all.
There's no curiosity or intellect featured here anymore. It's just bickering about semantics or pedantry. If that doesn't anger you, great. That's like a toddler saying they don't mind sharing a pool with other kids who urinate in it. That's your preference, not mine. Sorry for rubbing your face in your own drivel.
Water won't put it out but putting it in a big enough container of water and leaving it there long enough works. You just need a big enough energy sink + containment.
