Lithium Ion Batteries and Salt Water

A recipe for "energetic chemistry... Exploding Electric Bicycles | Power Line

John Hinderaker recently got an email because he purchased an electric bike. It starts as follows:

PLEASE BE AWARE: if partially or totally submerged in water, the lithium-ion battery pack used to power many electric devices and vehicles will suffer damage that will compromise its safety and stability. This damage can be even more severe if your battery pack was submerged in salt water.

Go read the rest, and follow the link to the electric bus fire video from China. Those are always exciting.

How many electric vehicles got submerged in Hurricane Ian? Of those, how many were engineered to account for submersion in salt water?

Sparky vehicles and salt water...

Energetic chemistry is a euphemism for explosion.
