Ebike catches fire....

This report is just like the 30mph ebikes story in that it bears no relation whatsoever to ebikes that are available for sale but tends to offer the view that all ebikes are iffy to say the least. After all if they will do 30mph it's no surprise that they all catch fire...

Not sure that throwing water on a lithium battery is a good idea, especially one still connected up to the mains!

Yes water is fine on a lithium battery. No water is not fine on a connected charger. Immersion in salt water is the recommended way to fully discharge and neutralise LiPo batteries I am guessing that it may be more complicated with Li-ion which are in metal cans.

so if one sets itself alight on a plane, it will be neutralised when it lands in the sea!!

Note: Beware which type you're dealing with. Pouring water on a burning Li-metal battery can make it worse. The recommended method for that is a dry powder extinguisher. I read that here

[Edit: Sorry, just to be clear, you can using any extinguisher (including water) for a burning Li-ion battery. If you can, get it outside and well away from anything it could ignite.]

Yes sorry wasn't clear I meant extinguisher.

I always thought Lithium was like Sodium, reacts violently with water?.
Lithium in metallic form doesn't exist in rechargeable lithium batteries, it's just an intercalated lithium compound. In fact it's when poor manufacturing standards result in the formation of metallic lithium crystals that fires occur. This is due to the growing crystals having a jagged formation which penetrates the internal insulations causing shorts and localised heating, building to fires.

Metallic lithium is used in primary (non-rechargable) cells.
