Good pictures.
Immersing a Lithium battery in water, after a fire has started, is probably the ONLY way to (eventually!) putting it out.....

Good pictures.
Good links, many thanks.I had thought that these were under control now but some recent fires

show that human error (using the wrong charger) or unfit knockoff ultra cheap internet batteries seem to be the main cause.
How true.Problem with scooters is the abuse they take and the fact the battery is low to the ground where it takes all the punishment. Also the charging, how many are plugged in and left connected after charging and forgotten about.
The huge amount of energy in a Bike battery, its more like "slow" dynamite, than burning.Would one of these put out a lithium battery fire? One could be kept above the battery while stored or charging. I may well order one:

Charge or store the battery in a sealed steel box filled with carbon dioxide? The gas would have to be kept warm...The huge amount of energy in a Bike battery, its more like "slow" dynamite, than burning.
IMHO only complete immersion in cold water, for some hours, is needed to stop the reaction completely.
Like fill your bath and only charge in the bathroom and have a method of "throwing" the burning battery into the bath!
But of course, having mains voltage and water together are most unsafe anyway!
All good houses have some form of residual current safety devices, or should have:-
But some still don't......Residual-current device - Wikipedia

Some expensive ones do just that, I am told, but some switch back on again too...We sent men to the moon (I wasn't involved) - surely in this day and age it's not beyond the realms of possibility that chargers could be made to stop charging, when the battery is fully charged?
I like it that you are thinking "out of the box", but its not going to help to stop these batteries from burning, as they already have their "OXYGEN" for burning, in the chemical makeup of the cells.Charge or store the battery in a sealed steel box filled with carbon dioxide?

A fire activated liquid nitrogen release system within a steel boxed off battery? It'd buy time to move said box to a swimming pool or garden pond, for the battery to resume burning. It'd burn through my plastic bathtub... maybe I should get an old cast iron bathtub for the garden.Some expensive ones do just that, I am told, but some switch back on again too...
Be careful what you buy!!

What needs to be done is to force cool the battery to stop the chemical reaction. Here in Germany for a time (I do not know if it is still done today), when a Tesla car catches fire in the batteries, it takes around 12 hours to burn out completely. So the German fire department would bring a large tank, fill it with water, and using a crane, dump the burning car in the tank.....it can still take between one and two hours to stop burning under water!
These are dangerous batteries if incorrectly used.....as I said before, "slow dynamite!"
I hope this helps.

There is quite a good case for NOT having batteries inside your house at all....... Somewhere dry, where if the battery does catch fire, it can cause far less damage.....Remember, the fumes are bad for the health of humans and animals....A fire activated liquid nitrogen release system within a steel boxed off battery?
