Hopefully never. If they ever do, it means the local government truly doesn't care about you anymore.

Na is basically Li times 30. This is good in that they make really effective batteries. This is bad in that when the battery malfunctions, the energy is released at 30x the rate. So remember when that Telsa caught fire and the driver walked away very scared but ok. If those were Na-ion, they wouldn't be ok...or alive...or recognizable as human. Basically, these are far too dangerous for consumer use. And any grid scale battery will need about a mile of gravel around them to prevent any fires or deaths from explosions.

Pretty that’s just not true.

Sodium ion batteries are less energy dense than lithium ion and are not prone to dendrite formation. They are also more thermally stable and less likely to do thermal run away reactions.

Also, since they are less energy dense they don’t store the same potential energy.

You are probably thinking of metallic sodium batteries which are completely different.

You have this flipped backwards

What? All the data suggests that sodium ion batteries are safer than lithium ion batteries: it is harder to set them into thermal runaway and they are less violent when they do so.

What bullshit are you spouting sodium batteries are safer and do not have the same thermal runway concern that lithium batteries do.
