This is why we need sodium-based battery solution out of the lab ASAP.
There is a catch with using sodium metal in batteries. Much like lithium metal, sodium metal reacts exothermically with water. During the reaction process, hydrogen gas is generated. With sodium, the amount of energy released can be enough to ignite the hydrogen gas if a large enough piece reacts at one time, causing an explosion. I used to show this situation as a lab demo to my students. (Potassium metal is even more reactive, it floats on the water on fire even in small pieces. It generates enough heat to ignite the hydrogen gas as it forms.)
As long as the sodium metal can be properly contained, the battery would be ok to use. But, how often would a crack form on the outside seal of the battery and cause an issue? People do really dumb things with batteries. The containers would have to be engineered to be fool proof. That issue would have to be resolved before sodium batteries have a chance of going on the consumer market.
