source and more detail: Safety Concerns with Li-ion Batteries – Battery University

which also says " Water-based products are most readily available and are appropriate since Li-ion contains very little lithium metal that reacts with water."

and slightly contradicts (re lithium quantity):

and ... "Despite their name, lithium-ion batteries used in consumer products do not contain any actual lithium metal." source: How Do You Put Out a Lithium-Ion Battery Fire?
 

and if you can't. (e.g. can't get to it / nothing appropriate to pick it up with / already ablaze etc ....)

reason for the post is that in the other thread there's a some incorrect thoughts in the best techniques to fight a li-ion battery fire.
 
RC car world, drop it in a bucket of water. Battery alone, or the whole car.
Last RC car battery I bought had disposal instructions, drop in salt water. Once battery voltage is zero it can be thrown away with normal trash.
I have popped a battery once. It was a failing pack. So I took a good cell and put a power supply to it and just turned it up until it popped. I've lit piles of black powder (gun powder) that were less energetic.

Lithium battery isn't a block of Lithium metal. As noted above, Lithium salt. Much like Sodium is very reactive in water, but sodium salt (Sodium Chloride) is what makes salt water salty.
 
I just bought a Lipo bag for charging
 
What about our homes? Kind of makes you think. I wonder if there are any stats on home fires caused by these batteries?
